Title:
BUTT WELDING TRUCK AND BUTT WELDING METHOD
Document Type and Number:
WIPO Patent Application WO/2020/054309
Kind Code:
A1
Abstract:
The present invention is provided with: a gantry loader body 23 which travels along a U groove Wu on the upper surface side of a butted portion between large panels W, W; and three welding torches 26 which are mounted on the gantry loader body 23 and are arranged side by side with distances therebetween above the U groove Wu. Among the three welding torches 26 which simultaneously move with traveling of the gantry loader body 23, the leading welding torch 26 performs penetration welding to form a penetration bead B on the lower surface side of the butted portion between the large panels W, W, the subsequent welding torch 26 performs build-up welding to make a buildup B2 in the U groove Wu, and the last welding torch 26 performs welding to make a buildup B3 for adjusting the appearance of the U groove Wu. When butt welding of aluminum alloy-made to-be-welded materials is performed, the welding work time can be shortened and welding deformation can be reduced while work for reversing the to-be-welded materials is omitted.
