Abstract
A weldment manufacturing method includes drilling that forms a hole on a workpiece, feeding a filler material to the hole and putting the filler material on a bottom of the hole, and melting the filler material by emitting a laser beam to the hole while scanning with the laser beam, so as to fill the hole with the melted filler material. By repeating the feeding and the melting, a weld repairing portion filling the hole is formed.
Claims16
A weldment manufacturing method, comprising:
- drilling a hole on a workpiece;
- feeding a filler material to the hole and putting the filler material on a bottom of the hole;
- and
- melting the filler material by emitting a laser beam to the hole while scanning with the laser beam, so as to fill the hole with the melted filler material, wherein
- a weld repairing portion filling the hole is formed by repeating the feeding and the melting.
2 more elements
A weldment manufacturing system, comprising:
- a drilling device configured to form a hole on a workpiece;
- a filler material feeding device configured to feed a filler material to the hole;
- a laser processing device configured to emit a laser beam to the hole while scanning with the laser beam;
- and
- a control device configured to control the drilling device, the filler material feeding device, and the laser processing device, so as to emit the laser beam from the laser processing device to the filler material fed to the hole while scanning with the laser beam, thereby melting the filler material.
2 more elements
A weldment, comprising:
- a first metallic member;
- a second metallic member;
- a weld line that bonds the first metallic member and the second metallic member;
- and
- a weld repairing portion that is a metallic material filled in the formed hole, the metallic material being identical to a metallic material of the weld line, wherein
- the weld repairing portion satisfies that H/d is between 5 and 20 inclusive and d is between 1 mm and 20 mm inclusive where H is a depth and d is a diameter, and
- the metallic material is layered in the weld repairing portion.
