“…According to [23], there exist a residual stress with lesser degree when pulsed welding current was used in the welding of 304L austenitic stainless steel compared to the constant welding current. It was reported that there was formation of fine grains in the microstructure as well as higher ultimate tensile strength, also yield strength tends to be high for the non-pulsed current compared to the pulsed welding current for the welding of the stainless steel [24]. For the TIG welding, the impact of the welding current was observed to produce excellent ultimate tensile strength compared with the weld done at higher current supply.…”

The study focused on the importance of the different welding parameters on the mechanical behavior of High Strength Steel (HSS) X65 steel pipes by reviewing the advantages of parameter optimization for the Tungsten Inert Gas (TIG) - Metal Inert Gas (MIG) welding processes. The parameters considered in the study include welding speed, welding current, welding voltage and gas flowrate of the welding. The effects of improper selection and parameter optimizations were highlighted and illustrated using different metallurgical and mechanical instances. The outcome of the study indicates that adequate parameter optimization aids in obtaining good weld quality with adequate mechanical and microstructural properties. Furthermore, it helps in the determination of variation in hardness in the heat affected zone as well as the base metal. Thus, this study provides insight to welding engineers on the importance of parameter optimization in the welding of steel pipe.

“…The study of Chennaiah et al [24] established that variation in the input heat of MIG welding of IS2062-EN31 dissimilar weldments have impact on the behavior of the welded components. The study established that application of low heat to fabricated joints demonstrates excellent metallurgical and mechanical behavior.…”
