    Actually we were not sure about the capacity and performance of laser welding since we had always been doing MIG and TIG in our workshop. We placed the first order after more than 3-month negotiation with Herolaser. Right now the machine is working pretty well with problems solved through online communication and videos guidance.

Product Description

Metals/Mould Repair Laser Welding Machine/Metal Parts Fiber Optic Laser Welding Machine

Model introduction:
Laser mould welding machine is the use of high energy heat generated by laser moment, the special welding wire melting and connected with the damaged parts of the mould, so as to firmly connect with the raw materials, and then through the electric spark, grinding, cutting and other processes to repair the mould. On the basis of many years of experience in laser welding development, Aohua has developed a special laser mold welding machine for the mold industry. It can accurately repair the small parts such as blisters, cracks, fragments and wear of the mold. Widely used in mobile phone, digital, automobile and other industries. Can repair all kinds of die forging steel, beryllium copper, copper and extremely hard alloy materials. Small heat affected zone, avoid mold deformation. Deep welding makes the connection firm. No repair marks are left after full melting, and there are no grooves at the connection between the raised part and the matrix.
Advantages and features:
  1. High accuracy , the welding spot diameter is only 0.2mm-0.5mm
  2. Little affect area , no distortion of the processing parts.
  3. No effect for etch after welding , low oxidation rate ,the color of the processing parts is intact .
  4. No stomata or sand hole disappeared after welding.
  5. Can process at the welding point , especially applicable to repairing mound requiring polishing.
  6. The processing parts can reach 50-60 rockwell hardness.
