As indústrias metalúrgicas de diversos segmentos buscam continuamente aperfeiçoar seus processos e reduzir custos de produção de estruturas metálicas. Variações em um processo térmico padronizado ou na configuração do produto podem causar alterações na microestrutura e nas propriedades mecânicas do, bem como, no comportamento mecânico do material. Assim, o presente estudo avaliou os efeitos das variações do ângulo de chanfro da junta em tubos de aço redondos AISI 4130 sem costura, quando soldados no processo TIG (Tungsten Inert Gas). Os tubos foram cortados com arco de plasma e preparados com ângulos, 30°, 45° e 60°, e 1 milímetro de altura da raiz. A soldagem foi realizada em dois passes, sendo o primeiro passe na raiz pelo método autógeno e o segundo de preenchimento com metal de adição arame-eletrodo AWSER80S-B2. As juntas soldadas foram submetidas a análises metalográficas de macrografia e microscopia óptica, para avaliação metalúrgica das zonas fundida e afetada pelo calor. Também foi realizado ensaio mecânico de tração e microdureza Vickers para verificar o desempenho mecânico e a dureza do material. A variável de interesse do estudo foi evidenciada por meio da estabilização do processo de corte e soldagem com uso de uma máquina rotativa digital desenvolvida no presente estudo. Os resultados obtidos evidenciaram uniformidade entre os cordões produzidos, variações nas geometrias dos cordões, no tamanho de grão e nas fases de transformação da microestrutura, com impacto na dureza da ZF (Zona Fundida), assim como no desempenho mecânico verificado com ensaios de tração. Conclui-se que, variações no ângulo da junta alteram a área de contato do arco com a poça de fusão, assim como, da poça de fusão com a ZAC. Com isso têm-se diferentes eficiências de transferência de energia térmica por condução, com diferentes ciclos térmicos que resultam em fases e transformações metalúrgicas distintas.
The metallurgical industries at several segments are continuously looking for improving their process and decrease metallic structures production costs. Modifications in a standardized thermal process or in the product configuration can leads to microstructure changes and in the mechanical properties,as well, in the mechanical behavior from the material. Thus, the current study made an assessment of the angle variation effect in steel round tubes joint AISI 4130 without seam, when welded by mechanized TIG process (Tungsten Inert Gas). The steel tubes were cross cut with plasma and prepared in three different angles 30°, 45° and 60°, with 1 millimeter height of root. The welding was made in two passes, the first one in the root by autogenous methode and the second one for filling using eletrode wire AWS ER80S-B2. The welded joints were submitted to metallographic test of macrograph and optical micrographics for metalurgical assessment in the melted zone and the heat affected zone. In addiction was made traction tests and micro hardness Vickers for verify the mechanical behavior and hardness from the material. The interest variable in this study, was evidenced by cut and welding process stabilization using a digital rotative machine developed in this study. The obtained results showed uniformity between weld beads produced with variation in the geometry, as well, in the grain size and in the fases transformations from the microstructure, with impact in the melted zone hardness profile, and in the mechanical properties verified by traction test. It´s pissible conclude that joint chanfer angle variations cause changes in the contact area size between the arc and the molten puddle, and between the molten puddle with the base metal. With this, diferent energy transfer efficency by conduction are obtained producing diferent thermal cicle, that can result in diferent metallurgical fases and microstructure transformations.

Neste trabalho é apresentado um estudo sobre a susceptibilidade à fragilização por hidrogênio de juntas soldadas de metais dissimilares presentes em equipamentos submarinos da indústria do petróleo, as quais ficam submetidas a condições de uso que envolvem esforços mecânicos severos, em ambientes corrosivos, proveniente da água do mar e do fluido petrolífero. O objetivo dessa pesquisa foi avaliar o efeito da utilização dos processos Plasma Pó (PTA-P) e MIG para a aplicação de "amanteigamentos" com Liga de Ni sobre a susceptibilidade à fragilização por hidrogênio de juntas soldadas de aços dissimilares utilizadas em aplicação offshore utilizando diferentes temperaturas de preaquecimento e interpasse e também comparar os resultados para dois aços para válvula, o AISI 8630M e AISI 4130. O processo de soldagem utilizado para a união das juntas foi o processo MIG utilizando-se como metal de adição o arame eletrodo, Inconel-625 (ER NiCrMo-3) de 1,2 mm de diâmetro. Os dois aços foram submetidos a três diferentes combinações de temperaturas de preaquecimento e interpasse antes dos amanteigados pelos processos PTA-P e MIG. Após a etapa de amanteigamento foram realizadas análises de composição química por EDS, microestruturais por MO e MEV, e de microdureza antes e depois do TTAT. Em seguida foram executadas as soldagens de união pelo processo MIG. As amostras de tração foram previamente hidrogenadas simulando as condições existentes de proteção catódica em ambiente submarino. O aumento das temperaturas de preaquecimento e interpasse resultou em maior refino dos grãos da ZTA, entretanto proporcionou aumento da média de sua microdureza e de sua extensão, e em maior migração de Fe do MB para o MS, resultando em maior fragilização por hidrogênio. Pelo processo PTA-P houve uma menor diversidade e frequência de incidência de zonas parcialmente diluídas (ZPD), sendo encontradas apenas ZPD do tipo contínua, enquanto que pelo processo MIG foram encontradas ZPD do tipo descontínua, com diferentes morfologias. O TTAT proporcionou uma significativa redução de 20% a 44% nos valores da microdureza da ZTA. Com base nos níveis de deformação e Índice de Fragilização (IF), o aço AISI 4130 apresentou os melhores resultados com relação à fragilização por hidrogênio.
This Thesis presents a study about hydrogen embrittlement susceptibility of dissimilar metals welded joints present in oil industry equipment, specifically in valves connections with pipes for the oil transport, which are subject to use conditions involving severe mechanical stresses in corrosive environments, from the seawater and the oil fluid. As the valves steel are martensitic its heat affected zone (HAZ) may be susceptible to hydrogen embrittlement not only from cathodic protection but also from the seawater and H2S. Therefore, to prevent this potential embrittlement and consequently crack formation in these regions of the welded joint, is used as nickel alloy filler metal. Therefore, the part of martensitic steel previously undergoes a "buttering" process which consists of applying layers of Ni deposited by welding. The welding process used for the union of the joints was the MIG process using as filler metal the Inconel-625 (ER NiCrMo-3) wire electrode 1.2 mm in diameter. Two steels were buttering, AISI 8630M and AISI 4130. Both were subjected at the three different combinations of preheat and interpass temperatures. For the buttering realization, the same alloy, in powder form, was used by Plasma powder process (PTA-P). To evaluate the efficiency of the PTA-P process in buttering operation it was compared with other buttering performed by MIG process with the same filler metal of the weld joint. After buttering the samples were subjected to post welding heat treatment (PWHT). Chemical composition analyses were performed by Energy Dispersive Spectroscopy (EDS), microstructure by Optical Microscopy (OM) and Scanning Electron Microscopy (SEM), and microhardness. After the welding the samples were machined and hydrogened using a process similar to those used for cathodic protection and submitted to tension tests. The Increase in the preheat and interpass temperature resulted in higher refining the grains of the HAZ however it, increased its average microhardness and extension, promoted greater Fe migration from MB to the buttering, increasing the hydrogen embrittlement. The use of PTA-P process promoted a very lower incidence and diversity of partially diluted zone (PDZ), being found only continuous PDZ. The PWHT promoted a reduction from 20% to 44% of hardness values. Based on the deformation levels and Embrittlement Index (EI), the AISI 4130 steel showed the best results with respect to hydrogen embrittlement.

Full textThe simulation using the finite elements method (FEM) has been of utmost importance for the tube hydroforming (THF) processes development. It reduces the try and error method in the process definition and great profits are gained. In this work, the FEM simulation together with the existing analytical THF theory in the literature was used to develop a process and a simple tool design for the THF, in open die arrangement and to be used in a common press. Gotten this tool, it was possible in a low cost, determine experimentally the forming limits, the strain paths and the evolution of geometry for a tube and then make it possible compares these experimental results with the simulated results obtained by FEM. This comparison of experimental and simulated results validated the simulation procedure and the tool design method. Relate the loads applied during the THF, two distinct load cases were possible: only pressure and simultaneous pressure and axial load, thus allowing proving the effectiveness of the second load case in obtain bigger expansion ratios. Relate to the simulations, they were run in commercial software and also the two load cases were simulated. Additionally in these simulations, two ways to apply the pressure had been evaluated. In the experiments, in the forming limits determination, the Circle Grid Analysis technique was used. A seamless stainless cold finished AISI 316 L solution annealed and quenched tube was chosen for evaluation. The tool design method, in a first attempt, uses the AISI 316 L steel properties obtained from sheets. Big differences between the FEM simulated and experimental results was gotten. Thus, it was necessary execute tensile tests in order to obtain the AISI 316 L steel properties for the seamless stainless cold finished, solution annealed condition. In such a way, a tensile tube test method called Ring Hoop Tension Test was used, to determined AISI 316 L steel properties in the transversal direction and a common tensile test was used for the longitudinal direction. Also, for both directions, anisotropy coefficients were also determined. With these new material properties set, new simulations including the anisotropy and a new improved tool design method were carried through, resulting in a new and improved tool version. Thus, new experiments were performed and compared with the new simulated results and the errors had diminished significantly. As final result, the errors in the diameter and in the thickness had been around of 10%, assuming the experimental result as standard. Relate the forming limits the results had differed, however the strain state and the strain path had been placed the same quadrant in a strain plane graphic (FLD diagram) for both load cases. Finally, relate to the tube expansion ratio, the tube external diameter increase 12,9% greater for tube expansion under pressure and axial load assuming the tube expansion under only pressure as standard.

Full textEquipment used in offshore oil production are subject to severe damage due toexposure to corrosive compounds present in the produced fluid. Therefore, corrosion resistant materials such as nickel base super alloy UNS N06625 (Inconel® 625), are used in the production fluid passage areas. However, the high cost of this alloy limits its use in all equipment. As a solution to this problem equipment with lower cost materials, overlaid with the noblest alloy, are manufactured. For these overlays the TIG twin hot wire welding process is seen as an option for generate quality weld with productivity. So the aim of this study is to determine the influence of the average current (Im), welding speed (Vs), feed rate (Va), filler material current (Ia) and shielding gas composition (Gs) on the dilution (D), penetration (P), width (W) and reinforcement (R) of the weld beads deposited by TIG twin hot wire welding process on steel AISI / SAE 4130. For this analysis it was used a DOE (Design of) central composite five factors planning totalling thirty-two (32) deposition conditions of weld beads. Using a stereoscopic and image analysis software, measurements of areas and dimensions of width, penetration and reinforcement were made in cross sections of the deposited beads. Furthermore, analysis of the chemical elements in these sections were performed using energy dispersive spectrometry to determine the content of Fe element and hence the dilution. To analyse the behaviour of variables and determine an empirical model, the response surface methodology (RSM - Response Surface Methodology) was used. It was found that all variables influence the dilution, and for the adopted model the minimal dilution obtained was 6.37%. In addition, It was obtained penetration between 0.37 and 2.16 mm, width ranging from 8.09 to 10.04 mm and reinforcement between 1.93 to 3.16 mm.

The main objective of this research has been to carry out a systematic study on the influences of various microstructures of a popular structural steel, AISI 4130 steel, on hydrogen-enhanced fatigue crack propagation. Some important effects have been discussed in this work, including those of microstructure, strength, hydrogen permeation, tempering temperature for tempered martensitic structures, and isothermal treating temperature for bainitic structures. In this work, some conclusions could be outlined: (1) For ferrite/pearlitic structures, the distribution of ferrite/pearlite along the path of hydrogen penetration affected hydrogen diffusivity deeply. Then the results of hydrogen diffusivity can be applied to explain the hydrogen-assisted fatigue crack propagation behavior of the banded and random ferrite/ pearlite structures successfully. (2) The variation of hydrogen-assisted fatigue crack growth rates of specimens sampled from different orientations for banded ferrite/ pearlitic structure was very significant, slight for random in the random ferrite/pearlitic structure. (3) A similar hydrogen-enhanced fatigue crack growth behavior and a transgranular fracture mode were found in bainitic structures, though they have different tensile strength and hydrogen permeation rate. (4) The hydrogen-assisted fatigue crack propagation rate of tempered martensitic structures increased as yield strength increased. In higher strength tempered martensites, an irregular fracture mode, in which the intergranular crack propagated easily near surface of specimen, was found. (5) The microstructural effect was the dominant factor on the hydrogen-assisted fatigue crack growth behavior. Alternatively, the strength effects could not been featured systematically.
