Resistance spot welding, 22MNBAS AS low alloy steel, Interfacial fracture

A typical automotive body would have between 3500 and 4000 resistance spot welds at a nominal rate of 40 to 60 welds per minute, which is a common rate for resistance spot welding (RSW), which is widely employed in the construction of automobile bodies. To reduce weight, high-strength steel sheets are widely employed in automotive body structures. The importance of evaluating the joints' quality using these sheets justifies further research to overcome specific quality issues. The interfacial surface of a 22MNBAS AS low alloy steel sheet that has been spot welded has fractured. The impacts of welding parameters like post heating duration and post heating current on the weld quality of 22MNBAS AS low alloy steel sheet are experimentally explored in this study to lessen this disadvantage. This sort of fracture is eliminated by heat treatment through post heating in the RSW process, according to metallographic analyses and destructive testing.
