Medium Power Fiber Delivered Direct Diode Lasers are mainly used for heat conduction welding of metal sheet. In heat conduc-tion welding, the laser beam melts the mating parts along a common joint. The molten materials flow together and solidify to form the welding seam. Heat conduction welding is similar to spot welding, but the laser beam moves after the welding pool is formed. Compared with traditional welding methods, laser heat conduction welding can not only reduce material deformation, but also process welding faster. In addition, it can achieve smooth and hole-free welding without any subsequent processing.
