“…Tensile strength, yield strength and microstructure were studied with newly developed TIG welding set up for welding of dissimilar aluminum alloy 5083 and 6061 [10]. The influence of parameters of argon gas metal arc welding on tensile strength of T-type joint was analyzed using Taguchi technique and finite element method [11]. Moreover, the effective TIG welding process for the welding of AA4043 is not studied so far.…”

Welding technology has played a vital role in the manufacture of complicated structures in automobile, petrochemical, aerospace, power plant, and ship industries. Tungsten Inert Gas welding process is superior technique and produces high quality weld economically. Aluminum alloy 4043 is currently preferred material in automobile, kitchen utensils and aviation industry sector due to its lightweight properties. The effective TIG welding process for AA4043 material is not studied yet with regard to micro-hardness, impact strength properties in correlation with the microstructure. Hence, consequence of welding parameters, namely welding current, voltage, and weld speed on micro-hardness, impact strength is studied based on Taguchi method. As per the developed experimental matrix, the TIG welded samples of AA4043 plates are produced using the tungsten electrode and filler wire of AA4043 in pure argon as shielding gas. Micro-hardness, impact tests are performed on welded samples and microstructures of different zones of weld are evaluated. Weld zone has highest micro hardness compared to heat affected zone (HAZ) and base metal due to presence of small grain structure. As current increases, large amount of solute enrichment in weld zone and HAZ, whereas severe grain structure change is predominantly observed in transition zone. The optimal parameters are obtained as welding current of 180 A, the voltage of 45 V and welding speed of 3.5 mm/sec for maximum micro-hardness of weld zone and impact strength of weld joint.

“…Fusion welding can be defined as the melting process of parent materials on facing surfaces with a filler material to form a weld bead. The fusion welding process comprises gas welding, arc welding, and intense-energy beam welding [3,4]. Such welding processes have many applications in different industrial sections, such as the manufacture of automobile bodies, aircraft frames, boilers, pressure vessels, ships, and tanks, as well as structural work and the repair of defects in both welded and cast products.…”

Solid-state welding (SSW) is a relatively new technique, and ongoing research is being performed to fulfill new design demands, deal with contemporary material advancements, and overcome welding defects associated with traditional welding techniques. This work provides an in-depth examination of the advancements in the solid-state welding of steels through diffusion bonding (DB) and friction stir welding (FSW). Considerable attention was given to DB of steel, which overcame the difficulties of segregation, cracking, and distortion stresses that are usually formed in liquid-phase welding techniques. The defects that affected DB included two types: two-dimensional defects of a metallic lattice, i.e., phases and grain boundaries, and three-dimensional defects, i.e., precipitation. FSW, on the other hand, was distinguishable by the use of relatively low heat input when compared to fusion welding processes such as tungsten inert gas (TIG), resulting in the formation of a limited heat-affected zone. Moreover, fine grain structures were formed in the FSW interface because of the stirring tool’s severe plastic deformation, which positively affected the strength, ductility, and toughness of the FSW joints. For instance, higher strength and ductility were reported in joints produced by FSW than in those produced by TIG. Nevertheless, the HAZ width of the specimens welded by FSW was approximately half the value of the HAZ width of the specimens welded by TIG. Some defects associated with FSW related to the diffusion of elements, such as C/Cr atoms, through the weld zone, which affected the local chemical composition due to the formation of rich/depleted regions of the diffused atoms. Moreover, the lack-of-fill defect may exist when inappropriate welding conditions are implemented. On the other hand, the stirring tool was subjected to extensive wear because of the high hardness values, which negatively affected the economical usage of the FSW process. A summary of the results is presented, along with recommendations for future studies aimed at addressing existing difficulties and advancing the solid-state technology for steel.

Gas metal arc welding (GMAW) is the leading process in the development of arc welding process for higher productivity and quality. In this study, the effect of process parameters of argon gas welding on the strength of T type welded joint of AISI 310 stainless steel is analyzed. The Taguchi technique is used to develop the experimental matrix and tensile strength of the welded joint is measured using experimental method and finite element method. Optimization of input parameter is performed for the maximum tensile strength of welded joint using ANOVA. The results showed that welding speed is the most significant factor affecting the tensile strength followed by voltage in argon gas metal arc welding (AGMAW) process. Argon gas welding process performance with regard to the tensile strength is optimized at voltage: 18.5 V, wire feed speed: 63 m/min and welding speed: 0.36 m/min.
