Effects of post-weld heat treatment on mechanical properties and microstructure of resistance spot–welded lightweight steel
Insung Hwang,Heewon Cho,Heewon Cho,Sangwoo Nam,Sangwoo Nam,Mun-Jin Kang,Minseo Koo,Young-Min Kim +7 more
TL;DR: In this article, a post-weld heat treatment (PWHT) was applied to resist spot welding to improve the mechanical properties of resistance spot welding and the required loads were satisfied when PWHT was applied at temperatures of less than 300 °C for more than 30 min and at more than 300°C for 15 min or more.

A Theoretical Model for the Dynamic Resistance in Resistance Spot Welds
Hyungsuck Cho,Y.J. Cho +1 more
TL;DR: In this paper, an analytical model that can predict the variation of the dynamic resistance variable is presented to obtain both the voltage and temperature distributions in the weldment, and the computed dynamic resistance based upon this model is compared with that experimentally obtained for the case of welding of mild steel.
