Frequently Asked Questions (FAQ)
1. Why use a tungsten inlay for seam welding?
It holds shape under rotation and heat, providing stable contact during long runs.
2. How long does the disk electrode last?
Lifetime varies with current, pressure, and sheet material, but tungsten inserts last longer than copper-only disks.
3. Can the disk thickness be customized?
Yes. We adjust diameter, thickness, and insert design based on drawings.
4. What materials can it weld?
Suitable for carbon steel, stainless steel, coated steel, and common industrial sheet metals.
5. How should it be maintained?
Keep surfaces clean, monitor cooling, and avoid excessive pressure during operation.
