Title: Welding equipment
Inventor: YAMANAKA MASAMI
IPC: B23K10/02
Filed: 2000-03-21
Abstract: PROBLEM TO BE SOLVED: To realize welding equipment by which a welding speed can be increased without a cost increase. SOLUTION: A preheating device 30 is equipped with a motor 31, a rotary member 32 mounted on the rotary shaft of the motor 31 and a spring 33 energizing the motor 31 in the arrow F1 direction. By pressing the tip of the rotary member 32 rotated by the drive of the motor 31 on the butt line L1 of a steel plate 40, friction heat is generated in a portion to be welded, and preheating is performed. By injecting a high temperature plasma stream 22 from the nozzle 23 of a torch 21 to a preheated portion, the portion to be welded is welded. Since mechanical preheating is performed by using friction heat, the cost can be lower than that of a preheating means using energy such as plasma and a laser beam.  Since the preheating by the friction heat is performed prior to performing plasma welding, the temperature of the portion to be welded can be raised to a target welding temperature faster than a case where the preheating is not performed. Therefore the welding speed can be increased.
