Laser welding machine is a kind of equipment for welding and processing metal materials. It has high power density, fast energy release, and processing efficiency is better than traditional welding. Whether it is welding the same material or different materials, it will not affect the surface and does not need to be welded. For secondary treatment, its appearance has made a new leap in welding technology.

Principle of laser welding machine

Laser welding is to use high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses rapidly to the inside of the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding repair.

Role of laser welding machine

Laser welding technology is a thermal processing process that uses laser beams as a heat source. It is a new type of welding method. The main welding objects are thin-walled materials and precision parts, such as stainless steel, carbon steel, mold steel, copper, aluminum, gold, Silver and other materials can be welded for point, line, circle, tube and special-shaped materials. Welding methods are spot welding, sealing welding, etc. It has the advantages of deep welding depth, small width, small heat-affected area, small deformation, and fast welding speed.

The laser welding machine can also repair and repair defects such as wear, pores, sand holes, cracks, scratches, defect deformation, and hardness reduction of the workpiece. Usually, no welding wire is needed. It is suitable for self-fluxing welding. Generally, welding seams larger than 1mm need to be repaired. Add wire, but wire feed welding will be slightly slower.

The power of the laser welding machine varies from large to small. The greater the power, the thicker the workpiece that can be welded. Generally speaking, the laser welding machine can weld materials with a thickness of about 8mm, but it is affected by the welding power, welding material and welding speed. The actual needs shall prevail.
