Abstract

This study employed the laser in-situ post-weld heat treatment process to achieve in-situ precipitation of carbides (IPC) in the hydrogen embrittlement (HE) sensitive zone of QP980 steels laser welded joints. In the original joint with hydrogen pre-charging, cleavage fracture occurred at the inter-critical heat affected zone (ICHAZ). The IPC process only caused carbides to precipitate in martensite of the ICHAZ. The IPC joint with hydrogen pre-charging (5 min) exhibited ductile fracture at the base material during the slow strain rate tensile test, and the total elongation HE sensitivity of the joint was reduced from 84.6 % to 13.7 %.
