SUGIURA Kazuki      KATSUKI Makoto      YANO Yoshiaki

Abstract

Dual torch welding system was developed for girth welding to improve welding efficiency on the pipeline construction. This is the first application of girth welding to pipeline construction in Japan, reducing the welding time by half at field, and enabling high quality girth welding. The developed dual torch welding system is introduced and the effect of application is reported.
