Abstract

As the state of the art in recent years Laser-Arc Hybrid welding is tried actively because of its various economical and technical advantages. In this study, melting tendencies according to the variation of laser-arc distance are investigated in case of YAG laser-TIG Hybrid welding process of AH32 ship structural steel. Nd-YAG laser with a laser beam power of 3KW is used and varied laser-arc distance 0mm to 10mm with fixing the TIG current as l00A. There is certain distance between laser and TIG elecrode to improve welding heat input and also increase the penetration.
