Sheet welding technology of high-power laser welding equipment

Abstract

The invention belongs to the technical field of sheet welding, in particular to a sheet welding technology of a high-power laser welding equipment. A fixing mechanism included in the sheet welding technology comprises a supporting plate. A ball screw is arranged between the two ends of the supporting plate in a connected manner. A fixing chamber is connected to the ball screw through a sliding platform. An insertion opening is formed in the top end of the side face of the fixing chamber. A sliding plate is in sliding connection with the bottom surface of the fixing chamber. A baffle and a locking plate are arranged at the top end of the sliding plate. A press plate is arranged between the sliding plate and the locking plate. A fastening bolt is in thread connection with the locking plate.Sheets are fixed to the fixing chamber. A positioning frame is arranged at the two ends of a weld joint between the two sheets in a sleeving manner. Laser welding heads are arranged at the two ends ofthe positioning frame. According to the sheet welding technology of the high-power laser welding equipment, the two sheets to be welded are stably positioned through the fixing mechanism, accurate and high-efficiency adjustment can be carried out on a gap of the weld joint between the two sheets, the welding technology is greatly optimized, and the quality of the welded sheets is improved.

Description

technical field [0001] The invention belongs to the technical field of thin plate welding, in particular to a high-power laser welding equipment welding process for thin plates. Background technique [0002] Laser welding has the advantages of good forming quality, small heat-affected zone, small workpiece deformation, less subsequent processing, and high flexibility. It is very suitable for welding and forming of metal sheets. Laser welding can be roughly divided into laser welding according to the heat conduction mechanism of welding. There are two types of heat conduction welding and laser deep penetration welding; when the laser heat input exceeds a certain threshold, the welding mode changes from heat conduction welding to deep penetration welding with "small hole effect", so as to realize full penetration welding of metal sheets. Under the condition of full penetration of laser deep penetration welding of thin metal plates, when the laser heat input is low, the welding...

AI Technical Summary

Problems solved by technology

[0004] Although the thin plate welding process in the above technology can improve the welding quality of the two thin plates, it is difficult because the two thin plates need to be spliced ​​in parallel before welding, and the splicing gap at the welding seam of the two thin plates is inconvenient to control, thus Affects the welding quality of thin plates
