mini 100W jewelry/desktop laser welding marking engraving machine for gold silver 925 denture la

High-magnification beam expander system to obtain finer spot and meet the requirements of fine laser spot welding The spot welding machine 200W is aimed at welding thin-walled materials and precision parts to realize spot welding, butt welding, overlap welding, and sealing welding. It is mainly used for making holes and spot welding for gold and silver ornaments, during spot welding. Is a heat conduction type, that is, laser radiation heating the workpiece surface, the surface heat through the internal diffusion, by controlling the width of the laser pulse, the peak energy, power and repetition frequency parameters, the workpiece melting, forming a specific molten pool. Adjustable high-brightness LED ring shadowless lamp, observing the workpiece without shadow, with high-definition body type Parallel light path microscope, laser welding position is more clearly observed
