Abstract:
The behavior of nitrogen into the dissimilar joining metal between AISI 304 and AISI 316L Austenitic stainless steel during gas tungsten are welding process was investigated. Studied by using an arc nitrogen atmosphere – controlling in chamber. The relations between nitrogen content of the dissimilar weld metal and the welding parameters, such as the welding current, welding speed, welding arc length and penetration area of weld metals were also evaluated. The results show that the nitrogen content of the weld metals decreased with an increasing welding current, and increasing penetration areas of weld metal, but scarcely depends on the welding arc length. The nitrogen content of the weld metals increased with the welding speed, but decreased penetration areas of weld metals. The role of nitrogen content on the dissimilar weld metals stainless steel is further confirmed by the experimental microstructure, mechanical and corrosion behaviour of the weld metal.

Abstract:
The welding of dissimilar materials finds a wide variety of applications in the fields of industrial construction and manufacturing, where the characteristic features of the different materials are optimized for the desired application to result in cost effectiveness and value addition. Non-fusion welding methods such as solid state welding and high energy beam welding are more popular for welding dissimilar metal combinations, due to fewer complications, than fusion welding, which melts the base metal and forms brittle intermetallic compounds (IMCs) that may lead to failure. Various factors have to be considered when assessing the feasibility of welding dissimilar metals and producing a sound weld joint. This paper presents a broad classification of the most commonly used welding processes for dissimilar materials, discusses some of the commonly used welding processes with examples of some common material combinations, critical factors for good welding, and practical difficulties arising from the physical and chemical properties of materials. From the findings, it can be inferred that continuous improvement and research is still required in the field of dissimilar metal welding, particularly in the light of increasing demand for tailored material for modern engineering and industrial applications.

Abstract:
In recent years Gas Metal Arc Welding (GMAW) technology has expanded its functionalities in various areas which have further motivated its usage in several emerging manufacturing industries. There are several issues and challenges associated with this technology, especially in dissimilar metal welding (DMW). One of the predominant challenges is selecting appropriate welding parameters which influence the efficiency of this technology. To explore several modern advancements in this expertise, this paper has done an exclusive survey on various standards of GMAW and its variants for selecting suitable parameters for welding dissimilar nonferrous metals. This review summarizes various experimental and numerical results along with related illustrations to highlight the feasibility of welding dissimilar nonferrous metals using traditional GMAW and investigations on advanced GMAW processes such as cold metal transfer (CMT) and pulsed GMAW (P-GMAW). Simulation and modeling of nonferrous DMW have identified several research gaps and modeling problems. Researchers and manufacturers can use this review as a guideline to choose appropriate welding parameters to implement GMAW and its variants for non-ferrous dissimilar welding. It found that by controlling the heat input and effective post-heat treatments, adequate joint properties can be achieved. Automated large -scale manufacturing will widen the utilization scope of GMAW and avoid some costly methods such as laser welding, ultrasonic welding, and friction stir welding etc.

Abstract:
Resistance spot welding (RSW) is the most widely used for joining thin sheet metals in automotive industry. Various applications of dissimilar materials and thicknesses were commonly found in many spot welding processes especially in the manufacture of car body. The resistance spot welding of dissimilar materials are generally more challenge than similar materials due to differences in the physical, chemical, and mechanical properties of the base metals. Differences of materials have an impact on heat input generated at the spot welding. Diameter of the weld nugget size is influenced by several parameters such as electric current, welding time, different types of material, and the thickness of the plate. Nugget diameter will influence on physical and mechanical properties weld such as microstructure, shear strength and hardness. For practical use, various industrial standards have recommended a minimum weld size for a given sheet thickness, mostly in the form of tables. For example the American Welding Society (AWS), Society of Automotive Engineering (SAE) and the American National Standards Institute (ANSI). They were only suitable to be apllied on the similar metal and thickness joint because in this joint, symetrical nugget will be formed. Meanwhile a type of dissimilar metal that joined by spot welding method will result in the asymetrical nugget. This paper aims to review the results of researchs on the similar and dissimilar resistance spot welded joint to evaluate the use of similar metals weld parameters and standards on the dissimilar metals weld. It was determined that parameters welding such as electric current, welding time, and the standard for similar metals weld can not be applied on the dissimilar metals weld. The asymetrical nugget shape decreased shear strength on the weld nugget. The most important factor that was considered on the dissimilar metals weld to make high quality weld joint was nugget diameter. If the nugget diameter weld increased the strength of welding will increase.

Abstract:
Two different aluminium alloys, AA6111 (Al-Mg-Si) and AA7055 (Al-Mg-Zn), were chosen as the aluminium alloys to be welded with DC04, and two welding methods (USW and FSSW) were selected to prepare the welds. Selected pre-welded joints were then annealed at T=400 - 570oC for different times. Kinetics growth data was collected from the microstructure results, and the growth behaviour of the IMC layer was found to fit the parabolic growth law. A grain growth model was built to predict the grain size as a function of annealing time. A double-IMC phase diffusion model was applied, together with grain growth model, to predict the thickness of each phase as a function of annealing time in the diffusion process during heat treatment. In both material combinations and with both welding processes a similar sequence of IMC phase formation was observed during the solid state welding. η-Fe2Al5 was found to be the first IMC phase to nucleate. The IMC islands then spread to form a continuous layer in both material combinations. With longer welding times a second IMC phase, θ-FeAl3, was seen to develop on the aluminium side of the joints. Higher fracture energy was received in the DC04-AA6111 joints than in the DC04-AA7055 joints. Two reasons were claimed according to the microstructure in the two joints. The thicker IMC layers were observed in the DC04-AA7055 joints either before or after heat treatment, due to the faster growth rate of the θ phase. In addition, pores were left in the aluminium side near the interface as a result of the low melting point of AA7055.The modelling results for both the diffusion model and grain growth model fitted very well with the data from the static heat treatment. Grain growth occurred in both phases in the heat treatment significantly, and was found to affect the calculated activation energy by the grain boundary diffusion. At lower temperatures in the phases with a smaller grain size, the grain boundary diffusion had a more significant influence on the growth rate of the IMC phases. The activation energies for the grain boundary diffusion and lattice diffusion were calculated as 240 kJ/mol and 120 kJ/mol for the η phase, and 220 kJ/mol and 110 kJ/mol for the θ phase, respectively. The model was invalid for the growth of the discontinuous IMC layers in USW process. The diffusion model only worked for 1-Dimensional growth of a continuous layer, which was the growth behaviour of the IMC layer during heat treatment. However, due to the highly transient conditions in USW process, the IMC phases were not continuous and uniform even after a welding time of 2 seconds. Therefore, the growth of the island shaped IMC particles in USW was difficult to be predicted, unless the nucleation stage was taken into consideration.

Abstract:
Dissimilar welding of Al to Mg alloys could potentially find significant application in the automobile industry, if the massive production of brittle intermetallic compounds (IMCs) at the joint interface can be prevented. In order to better understand Al-Mg IMC reactions, a comprehensive investigation of the interfacial region in AA6111 - AZ31 diffusion couples was carried out in this research. Three Al-Mg binary IMCs, namely the -Al12Mg17, -AlMg and -Al3Mg2 phases, were observed to form in the Al - Mg diffusion couple. In both the Al3Mg2 and Al12Mg17 layers, residual stresses were detected. The stress components normal to the joint interface were found to be positive, which had the effect of promoting the extension of lateral cracks; while the horizontal components were compressive, which could hinder cracking in the vertical direction. As a result, the fracture resistance of the two IMCs were asymmetric with lower values along the interface than in the vertical direction. The higher stress level in the Al3Mg2 layer made it more susceptible to lateral cracking and hence becoming the weak link in the Al - Mg dissimilar joints. A potential metallurgical solution has been explored involving the introduction of Zn into the material system, so that a new intermetallic compound with better properties can be formed to replace the unfavored Al3Mg2 phase. In this research, an Al-Zn coating alloy was proposed for this purpose. To determine the optimum composition for the alloy, a numerical method that combined CALPHAD thermodynamic calculation and diffusion simulations was developed. The modelling results indicated that Al-20 at. % Zn was the optimum composition for completely suppressing the formation of Al3Mg2, and this has been verified by static diffusion and friction stir spot welding (FSSW) experiments. In both cases, the designed coating alloy was effective in changing the Al-Mg reaction path by forming the mechanically superior (Al,Zn)49Mg32 phase as a substitute for Al3Mg2. The FSS welds prepared with the Zn containing coating alloy exhibited a 6 % increase in lap shear strength, compared to the conventional Al-Mg welds. This lower than expected improvement resulted from the Zn addition reducing the liquation temperature of the material system, resulting in the production of a detrimental eutectic mixture which facilitated debonding of the welds. As a potential alternative solution, Al-Si coating material has been proposed to inhibit the growth of Al-Mg IMC layers, in which the Si phase was expected to form a partial interdiffusion barrier between the substrate materials and change the reaction path by preferentially reacting with Mg. Comparison of long-term static diffusion experiments between the Al-Si coated and Al - Mg dissimilar joints showed that the nucleation and growth of Mg2Si could change the reaction path and greatly reduce the thickness of the Al-Mg IMC layer at the joint interface. Although in actual friction stir spot welding (FSSW), Mg2Si was not formed in a detectable amounts, due to the very short reaction time, the Al-Si coating still led to a significant reduction in the IMC thickness by partially blocking the Al-Mg interdiffusion process. With the coating applied, the Al - Mg dissimilar welds exhibited enhanced mechanical performance with both their strength and fracture energy being markedly increased, through a reduction in the IMC layer thickness and the presence of Si particle toughening the reaction layer by causing crack deflection.

Abstract:
Kela-2 Gas Field is the main supply for the West-East Gas Pipeline which runs across China with length of 4000 kilometers. Natural gas from Kela-2 contains CO2/H2S sour components and 10% condensation water, which makes the medium present very strong corrosivity. In avoidance of corrosion failure, DSS SAF2205 line pipes were introduced to transmit the gas from the Gas Field to gathering center and processing factory. The DSS pipeline is totally about 13km and it is the first time DSS pipes were used largely amount in oil and gas pipeline around the world. As it is known, DSS SAF2205 pipes and traditional linepipes X65 were welded together between the gathering lines and mainline. Properties of welding joints, especially corrosion resistance, are very important for the safety of the pipeline. In this paper, the dissimilar metal joints were welded by Metal Inertia Gas Welding (MIG) with ER2209 electrodes to study and optimize welding procedure. Optical microscope, scanning electronic microscope and energy dispersive spectrometer (EDS) were employed to observe microstructure and analysis alloy elements distribution in the jointing zone between the dissimilar steels. Along the dissimilar joint, the microstructure changes from duplex characteristic combination of Ferrite and Austenite to that with Ferrite and a few Pearlite or MA. Smooth and notch tensile test and low temperature impact tests were also used to investigate mechanical properties of the dissimilar joints. Corrosion resistance of dissimilar metal joints were tested and analyzed. Weld metal produced with ER2209 presents excellent resistance to general corrosion in 1M NaCl solution. It is found that the ER2209 electrode is more suitable for producing the dissimilar weld joint according to this job.

Abstract:
In this work explosive line and spot welding were used for the bonding of light-weight metal sheets. Materials involved are aluminum alloys 5052-O, 6061-T6, and 7075-T6, a magnesium alloy AZ31B-O and a commercially pure titanium (TP270C). Plates of similar and dissimilar metal combinations are explosion welded over a small overlapping area. The strength of the welds was measured using shear strength tests and the metal interface was analyzed using optical microscopy. The shear strength of the welds have been tested and appeared to high shearing strength. Explosive line and spot welding show a high strength to explosive mass ratio, making it a good candidate to be scaled up and used in commercial applications.

Abstract:
Alloy 600 and associated welds, Alloy 82/182 of the Pressurized Water Reactor (PWR) plants have been known as being susceptible to the Primary Water Stress Corrosion Cracking (PWSCC). Dissimilar metal (DM) piping butt welds were welded with Alloy 82/182. As one of the mitigation techniques of the PWSCC, Structural Weld Overlay (SWOL) has been applied to the DM welds, but it has tendency to occur weld cracks on the first layer. One of the reasons of the weld cracks is the sulfur which is highly contained in stainless steel base metals, because old stainless steels would contain higher sulfur (e.g. 0.02%) than later ones. In response to this situation, Magnetic Stir Welding (MSW) was proposed to apply for the first layer of SWOL, and tested to evaluate its weldabilities. MSW has been developed for several years, and it is generally known that MSW has characteristics to improve a heat transfer in the molten pool, so that it could reduce a dilution. The purpose of this study is to evaluate weldabilities of MSW for welding Alloy 52 and/or Alloy 52M as filler metal on high sulfur contained stainless steel pipe. Single bead tests and all position welding tests were conducted. As a result of this study, MSW can prevent from occurring weld cracks and lack of fusion due to stirring effects of the molten pool. Therefore, SWOL can be welded without weld cracks on the first layer by applying MSW, even though the stainless steel base metal contains relatively high sulfur. In addition, MSW can weld at high wire supply rate because of prevention of lack of fusion. So it could improve weld efficiency.

Abstract:
During the last year, defects had been located by ultrasonic testing in three of the pressurizer nozzle dissimilar metal (DM) welds at the Wolf Creek nuclear power plant. Understanding welding residual stress is important in the evaluation of why and how these defects occur, which in turn helps to determine the reliability of nuclear power plants. The analysis procedure in this paper included not only the pass-by-pass welding steps, but also other essential fabrication steps of pressurizer surge nozzles. Detailed welding simulation analyses have been conducted to predict the magnitude of these stresses in the weld material. Case studies were carried out to investigate the influences to main weld stress fields with different boundary conditions, material strength, weld sequencing, as well as simulation of the remaining piping system stiffness. A direct comparison of these analysis methodologies and results has been made in this paper. Weld residual stress results from nuclear industry (conducted by Dominion Engineering, Inc.) and the US NRC (conducted by Engineering Mechanics Corporation) are also compared.
