Technical means of laser welding machine

Laser WeldingMachineIt is a type of machine for laser material processing, also known as a laser welding machine and rust welding machine. According to its working method, it can be divided into laser mold welding machines (manual welding machines, automatic laser welding machines, laser spot welding machines, and fiber transmission laser welding machines).

    Optical welding uses high-energy laser pulses to heat materials in a small area and transfers the laser radiation energy to the welding target, causing the material to melt and form a specific molten pool. It is similar to the principle of laser welding machines. With the advancement of the times, laser welding technology is also continuously developing. Generally, filler wire laser welding does not use welding wire, but the assembly gap of the welded parts is quite large, making it difficult to guarantee in actual production, which limits its application range.

    Moreover, filler wire laser welding can greatly reduce the requirements for assembly gaps. For example, for aluminum alloy plates with a thickness of2 mm, the gap between the plates must be zero to achieve a good forming effect. If a1.6mmthick welding wire is used as the filler metal, a good weld can also be formed.

    In addition, the filler wire of the laser welding machine can also adjust the chemical composition or perform multi-layer welding on thick plates. The rotation of the laser beam and laser welding can greatly reduce the requirements for welding assembly and beam alignment. For example, in the butt joint of thick high-strength alloy steel plates, the allowable butt assembly gap is increased from2mmto0.14mm, while for0.25mmthick plates, the allowable misalignment error between the beam center and the weld center is increased from4mmto0.25mm, while for0.5mm.

    The laser welding machine is also known as a laser cold welding machine, laser hydrogen welding machine, laser welding equipment, etc. According to its working method, it can be divided into laser mold welding machines, manual laser welding equipment, welding machines, laser spot welding machines, fiber transmission laser welding machines, galvanometer welding machines, etc. Special laser welding equipment includes sensor welding machines and keyboard laser welding equipment.

    It is suitable for welding integrated circuit leads, watch clips, electronic gun components, sensors, high-power diodes (transistors, laptop shells, mobile batteries, electrical accessories, filters, stainless steel products, golf club heads, etc.), and zinc alloy processing.

    The working principle of the laser welding machine is to use high-energy laser pulses to heat materials in a small area. The laser radiation energy is guided to melt the material into a specific molten pool through heat diffusion. The laser welding machine is mainly used for welding thin-walled materials and precision parts. It can achieve spot welding, sealing welding, etc., with small weld width, minimal deformation, fast welding speed, no or simple post-weld treatment, no pores, precise control, high positioning accuracy, and easy automation.
