The principle of handheld laser welding machine is to use high energy laser pulses to locally heat the material in a small area, and the energy of laser radiation spreads through the heat to the inside of the material to melt the material to form a specific molten pool.
It is a new type of welding method, mainly used for welding thin-walled material precision parts, can realize spot welding, butt welding, stitch welding, sealing welding, etc., with small welding seam width, small heat-affected zone, small deformation, fast welding speed, flat welding seam, high welding quality. The precision can be precisely controlled, the positioning accuracy is high, and the automation is easy.
With the continuous development of science and technology, the traditional welding methods in many industrial technologies can not meet the special requirements of the material. The advantages of the new generation of handheld laser welding machine is low adhesive strength and wide heat-affected zone, especially in many industries has gradually replaced the traditional welding method.
Handheld laser welding machine can be applied to the following industries:
Sanitary industry: water pipe joints, tee, valve, shower welding.
Eyeglass industry: stainless steel, titanium alloy and other material buckle, precision welding outer frame and other positions.
Hardware industry: Welding of impeller, kettle, handle and other complex stamping parts, casting.
Automobile industry: engine cylinder head gasket, hydraulic tappet seal welding, spark plug welding, filter welding, etc.
Medical industry: stainless steel seals, medical apparatus, medical devices, structural parts welding.
Electronic industry: solid state relay sealing welding, connector welding, MP3 and other metal shell and structural parts. Motor shell and wire welding, fiber optic connectors, etc.
Household hardware: kitchenware, stainless steel door handles, electronic components, sensors, clocks and watches, precision machinery, communications, crafts and other industries, automotive hydraulic tappet and other high-strength products welding products.
The advantages of handheld laser welding machines are energy concentration, no pollution, small welding spots, wide range of weldable materials, high applicability, high efficiency and high speed welding.
Also, the following requirements apply to laser welding.
1. The products that have high requirement of welding seam.
2. Products with high automation.
3. Parts that need laser welding equipment to realize non-contact long-distance welding with high sensitivity.
