This project establishes suitable welding parameters for AHSS material iterations (DP600, DP780, DP800, DP980 and HSLA350). Material section thicknesses ranged from 1.0mm to 3.4mm. Five fusion welding processes (GMAW-Pulse/AC, GMAWPulse/DC, Laser-GMAW, Laser, and Laser-Plasma) were examined in this operation.
