Service Overview
Laser welding is an advanced welding technology that utilizes a high-energy-density laser beam as a heat source to instantly melt and fuse the surface of the workpiece. By precisely controlling parameters such as laser energy, pulse width, and frequency, it can achieve high-quality welding of various metals and some non-metallic materials. Compared with traditional welding methods, laser welding has significant advantages such as concentrated energy, small heat-affected zone, minimal welding deformation, high precision, and high speed.
Our laser welding equipment uses advanced laser generators and precise control systems to stably output high-energy, high-beam-quality laser beams. We are dedicated to providing high-precision laser welding services. Our professional technical team possesses profound knowledge of laser welding processes and extensive practical experience. We can accurately adjust processing parameters according to the characteristics of different materials and welding requirements to ensure welding quality. Whether it’s welding thin-walled parts or multi-layer welding of thick plates, we can provide our customers with high-quality and efficient laser welding services.

Frequently Asked Questions
What are the advantages of laser welding compared to traditional welding?
Laser welding offers concentrated energy, a small heat-affected zone, minimal welding deformation, and high precision; it also boasts high welding speed and production efficiency; it can weld dissimilar materials, demonstrating strong adaptability; and it produces high-quality welds with high strength and few defects. Traditional welding methods such as arc welding and gas welding, on the other hand, have large heat-affected zones, significant deformation, and relatively lower precision, making them unsuitable for applications requiring high precision and quality.
What types of material combinations can be welded using laser welding?
Laser welding can be used to weld various material combinations, including similar metal materials (such as stainless steel to stainless steel, aluminum alloy to aluminum alloy, etc.), and can also achieve welding of dissimilar metal materials (such as stainless steel to aluminum alloy, copper to aluminum, etc.). It can also weld some metal and non-metal materials (such as metal to ceramics, metal to plastics, etc., but requires special process treatment). If you require consultation on aluminum alloy laser welding technology, our engineers can provide guidance on parameter optimization and defect prevention.
What are the surface quality requirements for workpieces undergoing laser welding?
The surface of the welded parts should be as clean as possible, free from oil stains, rust, oxide scale, and other impurities, to avoid affecting laser energy absorption and welding quality. For workpieces with poor surface quality, pretreatment such as grinding and cleaning is necessary before welding. Furthermore, the assembly accuracy of the welded parts also affects welding quality; the assembly gap should be controlled within an appropriate range.
Do parts processed by laser welding require subsequent heat treatment?
This depends on the welding material and specific application requirements. Generally, due to the small heat-affected zone in laser welding, the welding stress is relatively low, and many parts do not require subsequent heat treatment. However, for some materials with special requirements for welding stress and microstructure (such as certain high-strength alloy steels), appropriate heat treatment may be necessary to relieve stress and improve microstructure properties.
