Welding of Low Carbon Steel Tubes Using Magnetically Impelled Arc Butt Welding: Experimental Investigation and Characterization

Magnetically impelled arc butt (MIAB) welding is a solid-state technique of that utilizes the heating effect high-speed rotating for formation weld. The process exhibits lower time and power consumption compared to conventional processes tube–tube joining. However, available research reports on MIAB Mild Steel (MS)1018 are still inadequate lack details required extending applications this process. Hence, study was undertaken investigate MS 1018 tubes. Experimental investigations were performed specifically designed newly fabricated machine. experimental trials involved varying parameters understanding their influence joint strength other weld characteristics. Microstructure consisted acicular ferrite which differed from microstructure heat-affected zone. These helped arrive at optimum parametric window specified ranges key viz. current, upset yield an efficient Chemical analysis indicated absence inter-metallics. MS1018 showed greater integrity when maintained, feasible deployment as economizer coils in boilers, pressure part tubes, automobile tubular component joining applications.
