| Laser welding is a technique that uses the laser light from a handheld laser welding machine to melt the base material and join the two parts together by changing the intensity and size of the laser beam. The laser light used in welding is invisible to the naked eye. Argon gas and a filler material corresponding to the base material are used as the medium to excite the laser. The laser beam generated by the excitation is focused by a lens and irradiated onto the base material. The output power and the width of the laser beam are changed according to the characteristics and thickness of the base material, so that the workpieces can be fused together. |
