Laser spot welding is one of the important ways in which laser material processing technology is applied. The spot welding process belongs to the heat conduction type, that is, the surface of the workpiece is heated by laser radiation, and the surface heat is guided to the interior for diffusion through heat conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted and a specific molten pool is formed. Due to its unique advantages, it has been widely used in industries such as aviation, aerospace, sports goods, jewelry, golf clubs, medical equipment, aluminum alloy dentures, instruments, electronics, mechanical processing, and automobiles. It is particularly suitable for repairing holes, spot welding lines, modifying sizes, gemstone inlaying, and welding claw feet in jewelry accessories such as gold, silver, platinum, titanium alloy, and stainless steel.

Spot welding is an important and basic aspect of laser material processing technology. When laser radiation heats the surface of work-piece, the surface heat diffuses to the interior through thermal conduction and melts the work piece by controlling the width, energy, peak power and repeating frequency of laser pulse to form specific molten pool. Because of this unique feature, it is widely used for spot welding, perforating, repairing, retipping and resizing of gold/silver/titanium/platinum jewelry and small accessories. Also widely used in aviation, aerospace, sports products, medical instrument, titanium alloy denture, instrument, electronics, machinery, automobile, etc
