Laser spot-welding is one of significant facets of laser processing in technique application. The laser spot-welding machine has the advantages of high speed, high efficient, high depth, small distortion, small heat effect, high welding quality, flat welding line, no pollution to spot, high efficient & no pollution and without any welding material.
The spot-welding course belongs to heating conduct type, that is the laser radiate for heating workpiece surface, the heat on workpiece surface can be diffused to interior through heat conduct, melting the workpiece to form special molten point through controlling the pulse duration, energy, peak power and repetition rate of laser pulse.
This machine is mainly applied to repair hole and spot-welding sand hole, widely applied to spot-weld micro precision components, such as jewelry, nickel battery, down-lead of integrate circuit, hairspring of horologe, kinescope and electron gun assembly etc.
