AST laser spot welding machine produced by our company is mainly used for filling holes and spot welding of blowhole in the gold and silver ornaments. The laser spot welding is one of the important applications in laser material processing technology. The spot welding process belongs to the thermal conduction type, i.e. laser radiation to heat the workpiece surface, and that surface heat is diffused internally through heat conduction. The work piece is melted through controlling the laser pulse width, energy, peak power and repetition frequency, the work piece is melted, forming the specific molten pool. Due to its unique advantage, it has been successfully applied in the gold and silver ornament, processing, and precision welding of small parts.
