Laser high-frequency composite welding device and welding method of laser high-frequency composite welding device

Abstract

The invention discloses a laser composite welding device, which comprises a conveying device, a control device, a clamping device, a high-frequency induction heater and a laser, wherein the conveying device carries workpieces and drives the workpieces to move, the control device is connected with the conveying device and controls the speed of the conveying device, the clamping device fixes the workpieces, the high-frequency induction heater heats the workpieces, the laser provides laser beams required by the laser welding, and the positions of the workpieces heated by the high-frequency induction heater are subjected to laser welding. The invention also discloses a welding method. The laser composite welding device solves the problem that in the prior art, the simple laser welding cannot reach the welding temperature, meanwhile, through the addition of a transmission device, the welding effect can be artificially controlled and regulated, the intelligent manufacturing is realized, and the work intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing equipment, and in particular relates to a laser high-frequency composite welding device and a welding method thereof. Background technique [0002] Laser processing technology belongs to advanced manufacturing technology. Using laser technology for welding is a new breakthrough. Compared with ordinary welding methods, it is easier to realize welding automation and facilitate welding of complex shapes. The temperature of materials after laser irradiation will increase, and at the same time in a short time Cooling down inside is equivalent to heat treatment, which is beneficial to improve the microstructure of the welding zone, and the strength of the welded joint is greater than that of the base metal. [0003] However, because the existing laser power is not large enough, it cannot meet the temperature requirements of welding. Contents of the invention [0004] The technical problem to be ...
