Principle and Category of Laser Welding Machine

Laser welding machine is also called laser welder or critical limited welding machine. The working way can be divided into laser module burn-in machine (manual welding machine), automatic laser welding machine, laser spot welding machine and optical transmission laser welding machine. Optical welding is to carry out local heating within small regions of materials through high-energy laser pulse. Laser radiated energy expands to the internal part of material through heat conduction, forming a special molten bath after the materials are melted so as to reach the purpose of welding.
 
Laser module burn-in machine
It is mainly used for module manufacturing such as mobile phone, digital products, automobile and motorbike and module repairing of modeled industry as well as manual welding.
 
Automatic laser welding machine
It is applicable to a straight line, circumference and another automatic welding of the metal workpiece and commonly used in a mobile phone battery, ornaments, electronic components, sensor, precise machinery, communications and arts, and crafts.  
It is more applicable to the welding of two parts at the same time, for instance, special welding process of resistance, capacitance, and electrodes.
 
Laser spot welding machine
It can be used for silver and gold ornaments, reperforating of electronic components, spot welding sand hole, and rabbet welding.
 
Optical transmission laser welding machine
It is characterized by excellent light beam quality and thin facula and applicable to the welding of microelectronic elements, precise parts, high-end digital components, optical connectors, and medical treatment instruments.
 
Special laser welding machine
Sensor welding machine
It is especially for the sealing welding of different underwater sensors, temperature sensors, and special sensors.
 
Principle of laser welding machine
Laser welding is to carry out local heating within small regions of materials through high-energy laser pulse. Laser radiated energy expands to the internal part of material through heat conduction, forming a special molten bath after the materials are melted so as to reach the purpose of welding. It belongs to a kind of new welding way. Laser welding is mainly applied for the welding of thin-wall material and precise parts and spot welding, butt welding, stitch welding, and calking welding can be realized with high depth-to-width ratio, small welding seam width, heat affected area and deformation, fast welding speed, even welding seam, and elegance. Only simple treatment is needed after welding. The welding seam quality is high without pore and can be controlled precisely. The focus spot is small, positioning precision is high and automation is easy to be realized.
