Letter Welding Machine



(1) Welding head can be moved up and down, front and back, left and right to realize regulating and positioning, it is suitable for welding of font edge height 0.5-20cm, operability is greatly increased.


(2) The optical path and the power control system use independent design, convenient movement and suitable for a variety of venues and does not affect the font welding.


  • Welding letter table horizontal direction is using track ball screw, it can be applied to large, small font welding, the operation table can be easily removable, and has very high precision and stability. The center positioning system can realize accurate welding for various characters.


  • The machine control system can control laser power waveform in precision, and the system set up optimization waveform values for different material. As long as select the corresponding material, it can achieve the best welding effect.


(5) Small heat affected area, does not cause deformation, better welding depth, firm welding, better melted, leaving only 0.2mm~0.5 trace inside but not in font surface. The convex part of solution material in the bath can bind of the substrate material without convex depression phenomenon.
