Mold Repair Cantilever Laser Welder
The WH-MW series is a cantilever YAG laser welder for mold repair and precision welding on chassis, auto parts, bearings and engineering machinery molds.
Product Overview
What This Machine Is Built To Do
The WH-MW series is a cantilever YAG laser welder for mold repair and precision welding on chassis, auto parts, bearings and engineering machinery molds. Power options of 200 W, 300 W, 400 W and 500 W produce welding depths from 0.1 mm to 3 mm with a 1064 nm wavelength. The ceramic cavity reflector is rated for 8 to 10 years working life, and the xenon lamp reaches 3 million shots. A 10X stereo microscope with cross cursor aligns the weld point before firing, while an integrated chiller keeps output stable during long repair sessions. It replaces TIG for small mold cavity repairs where heat distortion and post-weld machining time are the main cost.
- Welds mold steel, stainless, precious metals and hard materials without the distortion of TIG
- Ceramic reflector cavity rated for 8 to 10 years cuts long-term lamp and cavity replacement cost
- 10X stereo microscope with cross cursor aligned to laser spot speeds up precise weld placement
- Integrated high-power chiller maintains stable output during extended mold repair sessions
- Intelligent joystick handle allows quick parameter adjustment without stopping the weld
- Four power models from 200 W to 500 W match welding depth to the part being repaired

Comparison
How It Compares With The Alternatives
| TIG Welding | Laser welding produces less heat distortion and requires minimal post-weld machining, though TIG may be cheaper for large structural repairs |
|---|---|
| Standard Metal Cavity YAG Welder | Ceramic cavity offers 8 to 10 year life versus frequent replacement, reducing long-term maintenance cost despite higher initial price |
| Fiber Laser Welder | YAG allows precise pulse control for mold repair with lower peak power, while fiber is faster for long seam welding on sheet metal |
Operating Notes
Use Guide
- Check water chiller level before each shift to prevent output instability
- Clean microscope lenses daily to maintain cross cursor alignment accuracy
- Monitor xenon lamp shot count and replace before 3 million limit
- Use protective eyewear even with the light valve filter for added safety
- Adjust pulse width to 0.1 ms for thin material to avoid burn-through
