Kind Code:
A1
Abstract:
The present invention is characterized by including: a superimposing step in which a front surface (1b) of a first metal member (1) and a back surface (2c) of a second metal member (2) are superimposed; and a welding step in which the first metal member (1) and the second metal member (2) are hybrid-welded together using a hybrid welding machine having a leading laser welding unit (20) and a following arc welding unit. The present invention is also characterized in that in the welding step, laser welding and arc welding are performed by projecting a laser beam (LB) to an inner corner section (U) formed by the front surface (1b) of the first metal member (1) and an end face (2a) of the second metal member (2), along a set movement route (L1) set in the inner corner section (U), and the laser beam (LB) is oscillated so as to cross the set movement route (L1).
