FAQs
What materials can be welded?
Common weldable materials include:
- Mold steel (P20, 718, H13, NAK80, etc.)
- Stainless steel
- Carbon steel
- Some alloy steels
Not suitable for ultra-high hardness or ultra-thick large structural parts.
Will the mold easily deform after welding?
There will be no significant deformation.
QCW laser mold welding machine has a small heat-affected zone and concentrated energy, significantly reducing the risk of mold deformation compared to traditional welding methods.
Is it possible to weld directly onto a heat-treated mold?
Yes. QCW mold laser welding machine is particularly suitable for on-site repair of heat-treated molds, with minimal impact on overall hardness and dimensions.
What are the differences between QCW laser welding and ordinary pulsed laser welding?
Compared to ordinary pulsed laser welding, the QCW laser mold welding machine is specifically designed for the large mold industry, offering more precise welding results and more stable energy output.
Is the QCW mold laser welding machine water-cooled or air-cooled?
It uses a water-cooling system to ensure stable output even during prolonged operation.
What is the maximum welding depth?
The single-pass welding penetration depth is generally 0.5–1.5 mm, and deeper mold repairs can be achieved through multi-layer, multi-pass welding.
