Laser welding machine are mainly used for laser welding of long-distance and large workpieces, overcoming the limitations of workspace travel space. When welding, the heat affected area is small, which does not cause deformation, blackening, and traces on the back. Moreover, the welding depth is large, the welding is firm, and the melting is sufficient. Not only can thermal conduction welding be achieved, but also continuous deep penetration welding, spot welding, butt welding, overlap welding, seal welding, seam welding, and so on. Argon arc welding uses the burning arc between the continuously fed welding wire and the workpiece as the heat source, and the gas shielded arc ejected from the torch nozzle is used for welding. However, there are shortcomings such as large welding heat-affected area and large solder joints. At present, laser welding has been gradually replaced in precision mold repair.
Laser welding machine have the advantages of simple operation, beautiful welds, fast welding speed, and no consumables. They can be used for welding thin stainless steel plates, iron plates, galvanized plates, and other metal materials, and can perfectly replace traditional argon arc welding, stainless steel plates, iron plates, aluminum plates, and other metal materials. Due to the large heat-affected area of argon arc welding, the workpiece often causes deformation, excessive hardness, blisters, local annealing, cracking, pinholes, wear, scratches, undercuts, or insufficient bonding force and internal stress damage after repairing. shortcoming. Especially in the repair process of fine castings, small defects are highlighted on the surface.
Laser welding machines are advanced tools used for precise and efficient welding in various industries. They offer several advantages over traditional welding methods, such as:
- Precision and control: Laser welding machines provide precise control over the welding process. The focused laser beam allows for small and accurate welds, minimizing the heat-affected zone and reducing the risk of deformation and discoloration.
- Versatility: Laser welding machines can be used for a wide range of materials, including stainless steel, iron, aluminum, and other metals. They are suitable for welding thin sheets as well as thick workpieces, offering flexibility in various applications.
- High welding speed: Laser welding is a fast process compared to traditional welding methods. The concentrated energy of the laser beam allows for rapid heating and cooling, resulting in faster weld formation.
- Minimal distortion: Due to the small heat-affected zone and precise control over the welding process, laser welding minimizes distortion and warping of the workpiece. This is especially beneficial when welding delicate or thin materials.
- No consumables: Laser welding does not require the use of consumables such as filler wires or shielding gases, reducing material costs and minimizing waste generation.Compared to traditional arc welding, laser welding machine can save about 80% – 90% of electrical energy and reduce processing costs by about 30%.
- Various welding techniques: Laser welding machines support different welding techniques, including thermal conduction welding, deep penetration welding, spot welding, butt welding, overlap welding, seal welding, and seam welding. This versatility allows for a wide range of welding applications.
- Easy operation: Laser welding machines are designed for user-friendly operation. They often incorporate advanced controls and automated features, making them relatively easy to use and reducing the learning curve for operators.
- Aesthetically pleasing welds: Laser welding produces neat and precise welds with minimal spatter or defects. The high-quality weld appearance makes it suitable for applications where aesthetics are important.
- Compared with the laser welding machine, the damage to the human body is higher. The current density of argon arc welding is high, and the light emitted is relatively strong. The ultraviolet radiation generated by its arc produces a high ozone content during welding. Therefore, Try to choose a place with better air circulation for construction, otherwise it will cause harm to the body.
