Laser welding is the use of high-energy laser pulses to locally heat a material in a small area. The energy radiated by the laser is directed through heat transfer to the internal diffusion of the material, melting it and forming a specific molten pool to achieve the purpose of welding. It is a new type of welding method mainly aimed at the welding of thin-walled materials and precision parts, which can achieve spot welding, butt welding, overlap welding, seal welding, etc. It has high positioning accuracy, small weld width, small focused light spot, small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld seams, no need for treatment or simple processing after welding, and is easy to achieve automation. The non-contact operation method can meet the requirements of cleanliness and environmental protection.
Applicable scope
Widely applicable for welding metals and their alloy materials such as gold, silver, platinum, stainless steel, titanium, etc.
It is widely used in manufacturing, powder metallurgy, biomedical, electronic, automotive and other fields
