Abstract:
The performed research focuses on the complete replacement of the pipeline manufacturing process consisting in welding on SAW+MIG / MAG generators with the robotized Tandem MIG / MAG welding procedure, with low energy consumption.The Tandem MAG procedure was experimented on X52 MS steel plates destined for the manufacture of pipelines, measuring 400x150x12 mm, with Y-joints (30o).The welded joints were executed horizontally and unilaterally, with flux bed support, 3 welding seams, using for filler material two wires of the same quality, EN ISO 14341: G 42 4 M G3Si1 (Filcord C), measuring 1.2 mm in diameter, and shielding gas EN ISO 14175 (CORGON 18).The entire technological welding process was carried out in fully robotized, laboratory conditions, using the QIROX -315 welding robot, fitted with Tandem MIG/MAG welding equipment, type QUINTO-GLC 603.The welding seams were executed with the same Tandem MAG welding head, with two wires, taking advantage of the possibility to rotate the welding head so as to obtain welding seams with the wires either positioned one after the other (tandem), or transversally (perpendicular to the welding direction), obtaining, by correlation with the welding speed, optimal linear energies, implicitly, seams of various widths and penetrations.The results of the tests concerning the characterization of the obtained welded joints corresponded to the mechanical – metallographic tests, falling within the ranges provided by the applicable standards.The welding parameters used in the robotized Tandem MAG procedure may lead to remarkable advantages concerning the use of energy and filler metal. Thus, linear energies are about 40% - 45% smaller than in the case of the classical SAW+MIG / MAG process, with positive effects on the mechanical and metallographic characteristics of the welded joints, leading to significant reductions in energy consumption. Furthermore, the use of filler materials (wire, shielding gas) decreases by 10% - 15% as compared to the classical SAW+MIG / MAG process, leading, implicitly, to lower costs.As a consequence of the obtained results, MAG Tandem welding procedure may become an alternative to SAW submerged arc welding and combined SAW and MIG / MAG welding and a classical reference method for the manufacture of pipelines

Abstract:
Welding is one of the most versatile joining methods for constructing products and structures in nearly all industrial fields. Arc has been widely used as a cheap heat source for welding since carbon arc fusion welding was first applied to join Pb plates in about 1880. New welding technologies have been developed according to social needs or changes since 1960. Therefore, half-automated welding, automatic welding and highefficient welding have been developed for saving man-power and afterward full automation. First, tandem one-side SAW (submerged arc welding), high-speed rotational arc, high-heat input SAW, tandem wire MAG, etc. have been introduced as highly efficient welding processes. On the other hand, as gas-shielding arc welding processes, CO2 gas, MAG, man-power saving automatic welding, the use of a flux-cored wire, AC MIG, MIG with two wires, laser-arc hybrid welding, CMT process have been developed and most widely employed in the industries in conjunction with an advance in the welding heat sources from thyristor to inverter and nowadays digital inverter. Furthermore, robotization has been developed from spot welding robot to squire robot, multi-axes GAM robot, mobile robot, portable many-axes robot and 7 axes robot together with the development in welding sensors such as probe sensor, one-touch sensor, magnetic sensor, arc sensor, laser-slit light sensor, stereo CCD, etc. Recently, novel arc sources are not developed, but deep weld penetration and geometry are controllably obtained in TIG welding by active flux pasted on the plate surface, good use of an active gas and narrow oxidation treatment. Clean MIG process for steels is also developed by use of a unique solid-wire of double layers with different melting temperatures, and different hybrid heat sources of plasma and GMA or laser and MIG. Hybrid welding processes with CO2 laser and MAG, disk laser and MAG, fiber laser and CO2 arc or MAG has recently been applied in the shipbuilding industry. I thank the authors for their generous cooperation to the publication of new development in the welding technologies.

Abstract:
Throughout the history of modernization of welding processes, in many cases the research has focused on optimizing the location of energy in the welding area, with the continuous improvement of the quality of welded joints. The welding processes in shielding gas environment with fusible electrode (MIG-MAG) have achieved superior performances regarding the increase of the current density around of the welded joint, simultaneously with the increase of the universality degree of their application. This paper is based on researching the possibilities of concentrating energy in the welding area, seeking to obtain both more favorable energy yields and an increased quality of welded joints. In the paper are shown a some results obtained following a comparative study on 2 welding processes in MIG-MAG protective gas medium, differentiated mainly by the metal drop transfer mode: by spraying (Spray arc), respectively by synergistic transfer (Arc pulsed), applied for corner welding of alloy steel sheets.

Abstract:
Hybrid welding processes belong to a new group of welding varieties that most often combine two classic welding methods, such as laser welding with MIG/MAG welding or plasma welding with MAG welding. Modeling of welding stresses in this type of welding requires the definition of a new type of heat source model that combines a concentrated stream of energy with a classic heat source, which occurs in an electric arc. The paper presents the results of temperature field modeling in conventional MAG welding and hybrid plasma-MAG welding. In the first case, the heat source model described by Goldak was used, and in the second case, the Goldak model was combined with the developed rectangular heat source model with a homogeneous distribution. The temperature distributions obtained from the simulations were verified by spot temperature measurements during welding with thermocouples. A fairly good agreement of the numerical analysis results with the temperature measurements for MAG welding was obtained, while in the case of hybrid welding the discrepancies between the modeling and temperature measurements were greater. The results were discussed, indicating potential causes and factors influencing the obtained test results.

Abstract:
This diploma thesis deals with design of welding power supply for MIG / MAG and MMA technique with continuous output current 120 A. The first, theoretical part is devoted to welding process technology, physical characteristics of electric arc and description of individual welding methods. The thesis also deals with the concept of power converter. The design of the switched-mode power supply is based on a full bridge topology. In order to implement advanced controls of welding power supply, the ARM Cortex M4 microprocessor was selected. Due to the large power consumption of the stepper motor for drive the welding wire, an auxiliary switched-mode power supply was also implemented. The documentation describing the realization of the welding power supply and the results of the measurements are in the last part of the thesis. The welding power supply was successfully revived and reached nominal parameters. Inert gas welding has not been tested yet, due to lack of time caused by extensive work in order to complete mechanical realization.

Abstract:
The development of welding technology is constantly going forward mainly due to the reduction of production costs and the costs of additional straightening of weldments due to the welding distortion. Therefore, the leading producers of welding machine are coming with new methods and technologies. One of the innovations is also the tandem technology CMT Twin from the company Fronius. The experiment carried out in the diploma thesis confirmed that this is a very cost effective process. The CMT Twin is from the point of view of production costs of the weld cheaper variant and bring less heat into the material compared with conventional welding. Application equipment CMT Twin requires industrial robot, so the method is predestined for the series up to mass production. The CMT Twin finds application, for example in the automotive and shipbuilding industry.

Abstract:

This master thesis deals with problems in the arc length control in Pulsed MIG/MAG Welding. The main problem is that it is not possible to measure the arc length. In the present solution the voltage over both the electrode and the arc represents the arc length.

To improve the arc length control a model of the electrode melting has been built. One output from the model is the voltage over the electrode and with this voltage together with the measured voltage it is possible to calculate the voltage over just the arc. Then, having the arc voltage as a value of arc length the arc length control can be improved, which is showed in the end by simulations. Simulations with the present control system are compared with the new one, when the controller is able to control the arc voltage instead of the sum of both the electrode voltage and the arc voltage.

Abstract:
Welding is a common method for joining of metal or plastic construction parts. This report describes several different weld methods in general terms. The report focuses on the GMAW method, specifically MAG welding. A case study has also been performed for the company Wenmec. The task received from the company was to compare the mechanical properties of joints welded with the tube electrode called Nittetsu SM-3A and joints welded with the homogenous electrode called ESAB Aristorod 12.63. Both types of weld joint were welded with the MAG method with an Argon based shielding gas with 18% CO2. The final task of this study is to compare the cost of these electrodes and then help Wenmec to decide which electrode that is the most cost effective. Tensile testing, impact testing and fatigue testing were performed on the weld joint samples. The hardnesses, microstructures, failure zones and chemical composition were examined with optical microscopy and SEM. The weld time, the amount of consumed electrode and the weld energy was measured during welding. These properties were similar and the differences between the different joints could be ignored. Both weld joint types showed similar microstructures and hardnesses. The microstructure was ferrite with carbides or perlite at the grain boundaries. Some silicon oxides were found in the grains. The yield strength, ultimate tensile strength and cycles to fatigue failure were similar in the two joint types, but the Aristorod weld joint showed higher impact strength and elongation at break. The chemical composition showed that the SM-3A electrode was a metal cored electrode with some additions of deoxidizing elements and a Copper coating. The Aristorod 12.63 electrode also showed the presence of deoxidizing elements and likely had a Titanium based coating. The sheet metal used as the work pieces are called Ruukki Laser 355 MC and is steel with low Carbon content, some Manganese and some impurities. The SM-3A electrode was costlier than the 12.63 electrode. This work concluded that the 12.63 electrode was a better alternative for Wenmec due to the lower cost, higher impact strength and higher elongation at break
Svetsning är en vanlig metod för att sammanfoga detaljer av metall och i vissa fall plast. Denna rapport beskriver flera olika svetsmetoder och allmänna fakta kring dem varpå rapporten fördjupas inom GMAW metoden, specifikt MAG. Ett detaljfall studeras också då företaget Wenmec gett uppdraget att jämföra mekaniska egenskaper för svetsfogar svetsade med rörelektroden Nittetsu SM-3A respektive den homogena elektroden ESAB Aristorod 12.63. Båda fogtyperna svetsades med MAG metoden och en argonbaserad skyddsgas med 18 % CO2. Till sist berör detta arbete de svetsekonomiska aspekterna för Wenmec och om företaget bör byta elektrodtyp eller inte. Mekanisk provning som utförts var dragprovning, slagprovning och utmattningsprovning. Mikrostrukturen och hårdheten i svetsfogarna jämfördes samt brottytor och kemisk sammansättning undersöktes med SEM. Vid svetsning jämfördes svetstid och materialåtgång samt den så kallade sträckenergin. Svetstekniskt var de båda svetsfogarna så lika att skillnader kunde ignoreras. Det visade sig att de båda elektroderna gav upphov till svetsgods med likadan mikrostruktur och snarlik hårdhet. Mikrostrukturen visade sig vara ferritisk med vissa mängder karbid eller perlit vid korngränserna. Partiklar i mikrostrukturen visade sig vara främst kiseloxider. Cykler till utmattningsbrott, sträckgräns och brottgräns var snarlika mellan de båda svetsfogarna medan Aristorod 12.63 hade bättre brottöjning och slagseghet. Den kemiska analysen visade att SM-3A var en metallpulverfylld rörelektrod med vissa deoxiderande tillsatser och en ytbeläggning som bestod av koppar. Aristorod 12.63 hade också vissa deoxiderande tillsatser och hade troligen en titanhaltig ytbeläggning. Stålplåten som användes som arbetsstycke var Ruukki Laser 355 MC och är ett lågkolstål med en aning mangan och andra föroreningar. De ekonomiska aspekterna visar att SM-3A är ett dyrare alternativ än 12.63. Sammantaget kom detta arbete fram till att SM-3A inte är ett attraktivt alternativ för Wenmec då slagseghet och brottöjning var sämre och elektroden dessutom var dyrare.

Abstract:
O objetivo deste trabalho é estudar a influência dos parâmetros do processo de soldagem MAG com transferência do metal do tipo Curto-circuito Controlado (CCC) sobre a geometria do cordão de solda. Foi utilizado um dispositivo de soldagem automatizado para realização dos testes de simples deposição sobre um tubo de aço API 5L X65 diâmetro interno 204 mm e espessura 8 mm. Os parâmetros do processo analisados foram a corrente de pico de arco (Ia1), o tempo de atuação desta corrente (ta1), o tempo de atuação da corrente Ia2 (ta2), a velocidade de alimentação do arame (W) e a velocidade de soldagem (v). Tais parâmetros foram ajustados na interface homem-máquina (IHM) de uma fonte de potência microprocessada e do dispositivo de soldagem automatizado. As características geométricas do cordão de solda analisadas foram a largura, a altura do reforço e a penetração. Foi utilizado um Projeto de Experimento Composto de Segunda Ordem para obter a relação entre os parâmetros do processo e as características geométricas do cordão. Os modelos matemáticos obtidos foram considerados adequados, sendo possível determinar estatisticamente o nível de significância de cada um dos parâmetros controláveis – e de suas interações – sobre as respostas analisadas. Foram encontradas sobreposição e falta de fusão lateral em 60% dos corpos de prova avaliados, sendo levantada a hipótese de que a combinação de altos valores da corrente de pico de arco Ia1 com baixos valores do tempo de atuação deste parâmetro – ta1, aliada à utilização de gases de proteção com alta porcentagem de Ar, pode comprometer a eficiência de fusão nas laterais do cordão de solda. Os cordões de solda foram produzidos com quantidade reduzida de salpicos, representando um avanço do processo CCC quando comparado ao processo com transferência do metal por curto-circuito convencional. Os parâmetros controláveis Ia1 e ta1 produziram efeitos muito similares nas respostas de largura e penetração, quando considerados de forma isolada e também quando da interação destes com os demais parâmetros controláveis. A análise dos efeitos das interações principais revelou que Ia1 e ta1 são os parâmetros de maior influência nas respostas da geometria do cordão de solda, porém, com elevada dependência de um ajuste adequado da velocidade de alimentação do arame W para a obtenção de estabilidade do processo.
This work aims to study the influence of MAG welding process parameters with controlled short-circuit (CSC) metal transfer mode on weld bead geometry. The simple deposition weld tests were performed using a micro controlled power supply and an automatized device which enabled achievement of weld beads with standard conditions on API 5L X65 steel pipe whose inner diameter is 204 mm and thickness is 8 mm. The welding process parameters analyzed were the peak arcing current (Ia1), times (ta1) and (ta2), wire feed speed (W) and welding speed (v). Such parameters were set on Human-Machine Interface (HMI) of the micro controlled power supply and automatized welding device. The weld bead geometric features evaluated were width, reinforcement height and penetration depth. A Central Composite Face- Centred Design of Experiment was performed to obtain the relationship between the process parameters and the weld bead geometric features. Statistical analysis allowed development of mathematical models and they were found appropriate to determine the significance level of the process parameters – and their interactions – on output responses analyzed. Overlap and lack of fusion was detected on weld beads side in 60% of all specimens evaluated. The hypothesis formulated states that the origin of these discontinuities is from specific combination of parameters – high values of Ia1 and low values of ta1 together with usage of a shielding gas with high percentage of Ar – which would lead to lower fusion efficiency on weld bead side. The weld beads were produced with low spatter rates so it can be considered an improvement of the CSC process if compared with conventional short-circuit metal transfer mode. The peak arcing current Ia1 and time ta1 yielded similar effects on width and penetration depth, and it was valid when that parameters were taken both isolated and on interactions with other welding process parameters. The present study also revealed that Ia1 and ta1 are the most important parameters on influencing weld bead geometry, however, there is also strong dependence on a proper adjustment of wire feed speed W to obtain process stability.

Conselho Nacional de Desenvolvimento Científico e Tecnológico
The goal of this work is to improve the knowledge of the metal transfer in MIG/MAG welding and supply data to improve the elaboration of its models. In this intention, experiments were accomplished with steel (inverse polarity; Ar+5%O2 shield gas) and aluminum (inverse polarity, Ar shield gas) electrodes, with steel electrode and several shield gases (inverse polarity, Ar+5%O2+ of 0 to 25%He shield gases) and experiments with steel electrode in direct polarity (Ar+5%O2 shield gas). The flat position welds were filmed by a high-speed video camera using the shadowgraph technique. Kinematics and dynamics characteristics of metal transfers in those experiments were obtained experimentally (droplets arrival speed in the weld pool, in flight droplets average acceleration, effective quantity of movement), and the weld geometry, and compared whenever possible with experimental and numeric results available in literature. The results showed that the weld current influences the kinematics and dynamics characteristics of the drops in all of studied conditions, that the arc length influences the cinematic characteristics and dynamics in the welds with steel and aluminum electrodes, and in the steel welds with different shield gasses; that the shield gas doesn't exercise significant influence in the appraised characteristics, and that the current polarity only affects the cinematic characteristics and dynamics in globular transfer mode. Additionally, the welding current affects the weld penetration despite the use of approximately the same heat input, the arc length affect the steel and aluminum weld penetration and with different shield gasses, the shield gas didn't exercise influences in the values of the penetration but it altered the form of the weld and the current polarity didn't exercise influences the weld penetration, but just in width and reinforcement, being more slender the weld bead in direct polarity.
Com o intuito de aprofundar o conhecimento da transferência metálica em MIG/MAG goticular e fornecer dados para aprimorar a elaboração de modelos da mesma, foram realizados experimentos com eletrodos de aço (polaridade inversa, gás de proteção Ar+5%O2) e alumínio (polaridade inversa, gás de proteção Ar), experimentos com eletrodo de aço e vários gases de proteção (polaridade inversa, gases de proteção Ar+5%O2+de 0 a 25%He), e experimentos com eletrodo de aço em polaridade direta (gás de proteção Ar+5%O2). As soldas, em posição plana, foram filmadas em alta velocidade através da técnica da perfilografia. Determinou-se experimentalmente características da transferência metálica (diâmetro das gotas e sua freqüência de destacamento e o comprimento do arco elétrico), bem como as características cinemáticas e dinâmicas das transferências metálicas obtidas nesses experimentos (velocidade de chegada das gotas à poça de fusão; aceleração média das gotas durante a trajetória; quantidade de movimento efetiva das gotas) e a geometria dos cordões de solda, comparados sempre que possível a resultados experimentais e numéricos disponíveis na literatura. Os resultados mostraram que a corrente e o comprimento do arco influenciam as características cinemáticas e dinâmicas das gotas em todas as condições estudadas, que o gás de proteção não exerce influência significativa nas características avaliadas, que a polaridade do eletrodo só afeta as características cinemáticas e dinâmicas no modo de transferência globular e que a quantidade de movimento efetiva das gotas influencia claramente a penetração do cordão de solda apenas quando associada à mudança no modo de transferência de globular para goticular. Adicionalmente, a corrente de soldagem afetou a penetração das soldas, mesmo utilizando-se aproximadamente o mesmo calor imposto, o comprimento do arco afetou a penetração das soldas de aço e alumínio e com diferentes gases de proteção, o gás de proteção não exerceu influência nos valores da penetração, mas alterou a forma do cordão e a polaridade não exerceu influência na penetração da solda, mas apenas na sua largura e reforço, sendo mais esbelto o cordão de solda em polaridade direta.
