Induction heating and laser hybrid welding device and method for thick plate welding

Abstract

The invention relates to an induction heating and laser hybrid welding device for thick plate welding. The induction heating and laser hybrid welding device for thick plate welding comprise an installation plate and two welding plates, wherein a hole slot is formed in the middle of the top surface of the installation plate; first through holes are formed in the middles of the left end surface andthe right end surface of the installation plate; the inner ends of the first through holes communicate with the hole slot; a vertical micro servo motor is fixedly arranged at the upper end of the holeslot; the lower end of an output shaft of the servo motor is located in the hole slot; a first horizontal shaft is arranged in the first through hole in the right side; a second horizontal shaft is arranged in the first through hole in the left side; the inner ends of the first horizontal shaft and the second horizontal shaft are connected with the inner ends of the corresponding first through holes through sealing bearings; first bevel gears are fixedly arranged at the inner ends of the first horizontal shaft and the second horizontal shaft; a second bevel gear is fixedly arranged at the lower end of the output shaft of the servo motor; and the first bevel gears mesh with the second bevel gear. The induction heating and laser hybrid welding device for thick plate welding provided by theinvention has a wire feeding function and an air cooling function, only requires one motor for providing power, and is simple in structure, low in cost, and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of welding devices, in particular to an induction heating and laser composite welding device and method for thick plate welding. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. Due to its unique advantages, it has been successfully applied in the precision welding of micro and small ...
