Mold YAG Laser Welding Machine

Laser Welding Machine for Mould Repairing


Mold laser welding machine mainly used in large-scale moulds’ repairing. the machine is controlled by Industrial micro-Computer.YAG Laser mould welding machine is use the high energy of heat that instantaneously produced by laser to melt the special-purpose welding wire and connect it with the damaged parts of the mould so it can connect with the original material firmly, after that it shows a reface by electric spark and grind & cutting and some other processing and so the mould is repaired.

Main Feature:

  1. The energy, pulse width, frequency and light spot size can be adjusted in a large range to realize different welding effects.
  2. Use the most advanced light shielding system to eliminate the irritation to eyes by light during working.
  3. Large welding depth, firm and beautiful appearance, full melting, no traces , no bulges or dents
  4. Small heat affected zone, won’t cause deformation of the mold.
  5. It is able to work 24 hours continuously, stable performance
  6. Human-based design accords with ergonomics, no fatigue after long time working.
