Abstract
A manufacturing method includes i) emitting a primary laser beam along a primary trajectory on a boundary between a first member and a second member by a welding apparatus; ii) emitting an advanced laser beam along an advanced trajectory that does not overlap the primary trajectory by the welding apparatus; and iii) emitting a subsequent laser beam along a subsequent trajectory that does not overlap the primary trajectory and the advanced trajectory by the welding apparatus.
Claims3
A manufacturing method for a welded structure, the welded structure being manufactured by joining a boundary between a first member and a second member that abut against each other by laser welding using a welding apparatus, and the welding apparatus that emits a primary laser beam scanning the boundary between the first member and the second member, an advanced laser beam that an irradiation position of the advanced laser beam is in front of an irradiation position of the primary laser beam in a direction of movement, and a subsequent laser beam that an irradiation position of the subsequent laser beam is at rear of the irradiation position of the primary laser beam in the direction of movement,
- the manufacturing method comprising:
- emitting the primary laser beam along a primary trajectory on the boundary between the first member and the second member by the welding apparatus;
- emitting the advanced laser beam along an advanced trajectory that does not overlap the primary trajectory by the welding apparatus;
- and
- emitting the subsequent laser beam along a subsequent trajectory that does not overlap the primary trajectory and the advanced trajectory by the welding apparatus.
