Introduction of laser welding machine

Laser welding machine is a welding machine with laser as medium, and laser welding machine is also called laser welder.

Laser welding machine is a welding machine with laser as medium, and laser welding machine is also called laser welder. According to the general working method, it can be divided into laser mold welding machine, namely manual welding machine, laser spot welding machine, optical fiber transmission laser welding machine, and automatic laser welding machine. The principle of laser welding is to heat the material in a small area through a high-energy laser pulse to dissolve it, and the energy of the laser diffuses into the material to melt the material to a certain depth to achieve the purpose of welding.

Main features

In the 1970s, laser welding was mainly used for the welding of thin-walled materials and low-speed welding, and the welding process belonged to heat conduction welding. That is, the surface of the workpiece is heated by laser radiation, so that the heat of the surface is diffused to the interior through thermal conduction, and the workpiece is melted by controlling the parameters such as the energy, peak value, width, repetition frequency and power of the laser. out a specific molten pool. Because of this special advantage, mechanical welding has been successfully applied to the precision welding of micro and small parts. Until the popularity of high-power CO2 lasers and high-power YAG lasers in the industry, laser welding has also opened up new fields. With the small hole effect as the theoretical basis, laser welding has been widely used in heavy industries such as automobiles, machinery, and steel.

Types of laser welding machines

Laser welding machines are also often referred to as laser welding machines, laser welding machines, laser cold welding machines, laser welding machines, laser welding equipment, laser xenon welding machines, etc. According to the working method of the laser welding machine, it can be divided into a variety of equipment, such as: automatic laser welding machine, laser mold welding machine (manual laser welding equipment), optical fiber transmission laser welding machine, jewelry laser welding machine, laser spot welding machine, handheld welding machine, galvanometer welding machine, etc., special laser welding equipment for silicon steel sheet laser welding equipment, sensor welding machine, keyboard laser welding equipment. It is mainly used for welding jewelry, battery nickel strips, integrated circuit leads, clock gossamer, picture tube, electronic gun assembly, sensor, tungsten wire, high-power diode (triode), aluminum alloy, laptop case, mobile phone battery, mold, electrical accessories, filter, oil nozzle, stainless steel products, golf ball head, zinc alloy crafts, etc. The graphics that can be welded are: circles, spot welds, straight lines, squares, rectangles, or graphics of any plane drawn by CAD software.
