There are many types of welding machines, including single-point single-function, single-point dual-function, and single-point multi-function. There are also two-point, three-point, four-point and even six-point welding machines and four-point welding machines. Different types of welding machines have different welding functions and work efficiency. Follow the editor of Welded mesh welding machine to see what are the welding principles and characteristics!
1. Welding principle
The laser welding machine uses high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted to form a specific molten pool. It is a new type of welding method. Laser welding is mainly aimed at welding thin-walled materials and precision parts. It can realize spot welding, butt welding, stitch welding, sealing welding, etc., with high aspect ratio, small weld width, and heat-affected zone. Small, small deformation, fast welding speed, smooth and beautiful welding seam, no need or simple processing after welding, high welding seam quality, no air holes, precise control, small focus spot, high positioning accuracy, and easy to realize automation.
2. Welding characteristics
1. It belongs to fusion welding, which uses laser beam as energy source to impact on the weldment joint.
2. The laser beam can be guided by a flat optical element (such as a mirror), and then a reflective focusing element or lens is used to project the beam on the weld.
3. The laser welding machine is a non-contact welding. No pressure is required during the operation, but inert gas is required to prevent oxidation of the molten pool. Filler metal is occasionally used.
