A study on shrinkage residual stresses, microstructure and mechanical properties of ASS thick pipe welded by GMAW process
In this investigation, AISI 304LN austenitic stainless steel pipes having 25 mm thickness and 300 mm inner diameter with conventional and narrow groove were welded by continuous current gas metal arc welding (GMAW) and pulse current gas metal arc welding (P-GMAW) process.A gas tungsten arc welding (GTAW) process was used for the welding of the root
