Abstract
A laser light L is emitted from a laser light source 6 to works 1, 2, to form a laser molten weld pool 3, and immediately thereafter, an arc molten weld pool 4 is formed using an arc welding machine 7; thereby plates 1, 2 are welded. The arc welding machine 7 is provided with a filler wire to form a bead 5 on the plate 1. With the welding process according to the present invention, works can be efficiently and securely welded regardless of shape and material of the works.
Claims2
A welding process for welding a work comprising the steps of:
- forming a molten portion on the work by emitting a high-density energy beam thereto;
- and
- immediately thereafter, generating an arc discharge while supplying a filler wire to the molten portion, to weld the work.
