With the continuous development of science and technology, Laser technology It is also more and more widely used in various fields, Laser welding equipment It has also become an important member. How can laser welding equipment occupy a certain market position among many mechanical equipment?
Welding process parameters and conditions
The selection of laser welding process parameters and conditions directly determines and affects the quality of weld pool. The selection of process parameters and conditions is based on the test of the reference value of welding base metal of the same material. After welding, the weld penetration, appearance and strength conditions are analyzed and adjusted. Among them, the process parameters mainly include laser power, welding walking speed, type and flow of shielding gas, etc.
Tooling positioning fixture
Because of its energy focusing structure, laser welding determines that its thermal energy instant melting has small influence area and small spot diameter. Therefore, the gap between base metal materials needs to be strictly controlled, and its weld strength is difficult to ensure. The structural design of the tooling fixture of the inflatable cabinet box and the disassembly method of the process flow determine the fitting clearance for the positioning and pressing of the workpiece. According to the structural characteristics of the workpiece, the production conditions of the user and the output arrangement, the laser welding of the inflatable cabinet box is divided into multiple processes. Laser penetration welding completes accurate positioning and fitting through a single set of fixture to directly complete the welding, while laser seal welding requires positioning and spot welding of various parts, and then completes the whole seal welding process through the cooperation of automatic conveying and displacement device.
Seam tracking
The deviation of workpiece positioning causes the deviation between the teaching position of welding laser beam and the actual fitting position of workpiece, resulting in unqualified weld quality. In addition, the size and specification of the workpiece in the inflatable cabinet are relatively large, and the continuous input of laser beam heat will cause a certain amount of deformation of the workpiece. The mechanical micro touch probe device is used to find the weld position, and the position detection and real-time compensation are carried out during the welding process, so as to ensure that the welding position does not deviate from the bonding surface of the workpiece.
With the continuous updating and subdivision of technology, laser welding technology will meet the needs of more users and provide process technology for more industries at that time.
