Document Type and Number:
WIPO Patent Application WO/2018/163808
Kind Code:
A1
Abstract:
Provided is a consumable electrode arc welding method for welding a first base material (41) and a second base material (42) by generating an arc (8) while moving a welding wire (5) from a first location to a second location along portions to be welded of the first base material (41) and the second base material (42) to be bonded, the consumable electrode arc welding method comprising: a magnetic path forming step for forming, between the first base material (41) and the second base material (42) at a position closer to the second location than the first location, a short-circuit magnetic path having magnetic permeability higher than in other locations; and a welding step for welding the first base material (41) and the second base material (42) by supplying a welding current of an average current (30) (0 A) or more to the welding wire (5) while moving the welding wire (5) from the first location to the second location at the portions to be welded.
