Abstract

Multipass laser welding technique using filler wire was developed. Welding parameters were optimized, which include assist gas pressure, wire feeding position, wire feed rate and gap width. Wire-laser beam interaction, plasma ignition and growth, metal transfer and energy coupling ratio of the wire in free spece and the work in the gap during bead formation were analyzed. Based upon these results, multipass welding of thick plate was demonstrated.
