1. Introduction of welding technologyArc: A strong and lasting gas discharge phenomenon, there is a certain voltage between the positive and negative electrodes, and the gas medium between the two electrodes should be in an ionized state. When igniting the welding arc, the two electrodes (one pole f

Ultrasonic welding machine has the advantages of high speed, energy saving, high fusion strength, good electrical conductivity, no spark, near cold working and so on. It can be used for similar metal welding, and can be used for spot welding and multi-point short strip welding of single and thin non-ferrous metals (such as copper, silver, aluminum and nickel). It can be widely used for welding of various shapes, such as connecting parts of fuse-type lithium batteries. Laser welding machine is a new welding method. Laser welding machines are mainly used for welding thin-walled materials and precision parts. It can realize spot welding, butt welding, lap welding, sealing welding, etc. It has high aspect ratio, small welding width, small heat affected zone, small deformation, fast welding speed and smooth and beautiful welding. Processing or simple processing is required after welding, high welding quality, no air holes, accurate control, small focus, high

Due to the unique advantages of laser welding head welding technology, in automobile manufacturing and production, the frame, body, carriage, engine, automobile gear, roof, etc. are inseparable from welding head technology. Laser welding head welding has small deformation and weld quality. High, no solder and other characteristics, become the standard process of automotive parts manufacturing.

Characteristics and application fields of laser welding head Laser head technology uses a polarizer to reflect the beam produced by the laser in order to focus it in a focusing device to produce a high-energy beam. If the focus is close to the workpiece, the workpiece will melt and evaporate within milliseconds. This effect can be used to generate high-power CO2 and high-power YAG lasers during the welding process, opening up a new field of laser welding head welding. The key to laser welding head equipment is a high-power laser. There are mainly two types, one is solid state laser, also known as Nd:YAG laser. Nd (Neodymium) is a rare earth element and YAG stands for Yttrium Aluminum Garnet, which has a crystal structure similar to ruby. The wavelength of the Nd:YAG laser is 1.06 μm.
