Abstract

As new joining methods, applicability of laser beam welding or laser/arc hybrid welding on joining of high strength steel has been examined. In this paper, a series of experiments and analyses were conducted to elucidate distortion and residual stress generated by laser/arc hybrid welding on high strength steel HT780.
