Welding apparatus and control method for welding apparatus

A welding apparatus configured to weld a base material through a wire material melted by a welding laser, comprising:

• a laser applicator configured to apply the welding laser to a welding area;
• a wire feeder configured to feed the wire material to the welding area;
• a detector provided on the wire feeder and configured to detect a feed amount of the wire material per unit time;
• a robot configured to move the welding area or the wire material by moving the laser applicator and the wire feeder;
• and
• a controller configured to respectively control the laser applicator, the wire feeder, and the robot, wherein
• the controller is configured to perform:
• controlling the wire feeder to stop feeding the wire material to the welding area;
• then controlling the laser applicator to stop applying the welding laser to the welding area;
• then controlling the robot so that the laser applicator and the wire feeder are separated from the welding area and the welding area and the wire material are separated from each other;
• determining whether the wire material has been welded to the base material based on the feed amount of the wire material per unit time detected by the detector;
• controlling the laser applicator to apply a cutting laser to separate the wire material welded to the base material without controlling the robot to stop when it is determined that the wire material has been welded to the base material;
• and
• controlling the laser applicator to stop applying the cutting laser to the welding area based on the feed amount of the wire material per unit time detected by the detector.
