Abstract
A laser welding apparatus (1) includes a laser welding head (5) configured to irradiate a workpiece (10) with laser light, a welding filler feeding mechanism (6) configured to supply a welding material to a position on which laser welding is performed, and a hollow structural moving mechanism (100) configured to move a welding unit (50) including the laser welding head and the welding filler feeding mechanism. The hollow structural moving mechanism has an insertion portion (3a) through which wire materials (41 and 62) of the laser welding head and the welding filler feeding mechanism are inserted.
Claims14
A laser machining apparatus comprising:
- a head having an optical outlet from which laser light is output;
- an optical cable attached to the head;
- a nozzle attached to the head to direct a material supplied to a target;
- a moving mechanism having a driving portion;
- and
- a controller,
- wherein the moving mechanism includes a first mechanism to allow the head to move in a curved manner in at least a two-dimensional plane and a second mechanism, which has a rotational axis, to allow the head to rotate 360° or more around the rotational axis along with the optical cable and the material, and
- the controller has an attitude control mode in which the moving mechanism is controlled so that the head rotates around the rotational axis while the head moves in the curved manner in at least the two-dimensional plane.
A laser welding apparatus which performs laser welding on a workpiece, comprising:
- a laser welding head configured to irradiate the workpiece with laser light;
- a welding filler feeding mechanism configured to supply a welding material to a position on which the laser welding is performed;
- and
- a hollow structural moving mechanism configured to move a welding unit including the laser welding head and the welding filler feeding mechanism, the hollow structural moving mechanism having an insertion portion through which wire materials of the laser welding head and the welding filler feeding mechanism are inserted,
- wherein, in a state in which a wiring material of the laser welding head and a wiring material of the welding filler feeding mechanism are inserted through the insertion portion of the hollow structural moving mechanism, the laser welding head is allowed to rotate 360° or more around a rotational axis.
