This machine is specially designed for jewelry laser welding, which is mainly used in jewelry patching holes and blister repairing. Laser spot welding is one of the most important applications for material processing technology. The procedure of spot welding belongs to heat conduction type, that’s to say the laser radiation heat the surface of the workpiece, the heat on the surface spread toward inside by heat conduction. By controlling the parameters as width, energy, peak power and repeat frequency, etc. of the laser pulse, workpiece will be melted and formed special molten pool. Due to the particular advantage, it has been successfully used in processing gold and silver jewelry as well as welding tiny and small parts.
