Laser spot welding is one of the important applications of laser technology in material processing. The spot welding process belongs to heat conduction type, i.e., it uses laser pulse of high energy to partially heat the micro area of materials, and after diffusion to the inside of material through conduction, the material will be melted and special molten pool will be formed. The series products are mainly used for hole repair of metal ornaments, sand eye spot welding, seam repair, welding of ornaments and welding of micro precise parts. During the welding process, the heat influencing area is relatively small and the welding spot can be adjusted. It covers such industries as golden and silver ornaments, electronic communications, hardware, clocks and watches, stainless steel and titanium metal etc. The laser spot welder produced by Nange Company has such advantages as rapid speed, small deformation, high welding quality, flat welding seam, free of intermediate brazing filler metal, firm and beautiful welding spot, free of pollution, small volume and convenient operation etc. Laser work medium Nd:YAG Average laser power 60W,70W Maximum output power 100W Central wavelength 1064nm Maximum single pulse energy 40-50J Minimum welding molten pool 0.1mm Pulse width 1-20 ms Welding depth 0.05-2mm Pulse frequency 1-20 HZ Gathering facular diameter ￠0.2-1.5mm Power supply 220V, 50HZ, 3.5KW Dimensions 830mm?00mm?100mm Weight 90KG
