Specialized mills with TPT, HF, Laser, and Combi welding technologies
Harve Ace supplies complete stainless steel tube and pipe mills across four welding technologies. TPT (TIG Plasma TIG) welding delivers the highest weld quality for pharmaceutical, food processing, and chemical applications. HF welding provides cost-effective high-speed production for commercial stainless tubes.
Laser welding achieves the narrowest heat-affected zone for precision thin-wall tubes in automotive and heat exchangers. Combi-Mills combine SAW and TPT for maximum flexibility across large-diameter stainless applications.
| Technology | Weld Quality | Speed | Wall Thickness | Best Applications | Cost |
|---|---|---|---|---|---|
| TPT (TIG Plasma TIG) | Highest | Low-Medium | 0.5-4mm | Pharma, Food, Chemical | Higher |
| HF (High Frequency) | Good | High | 0.8-6mm | Commercial, Structural | Lower |
| Laser | Excellent | Medium-High | 0.3-3mm | Automotive, Heat Exchangers | Medium-High |
| Combi (SAW+TPT) | Very Good | Medium | 2-12mm | Large Diameter, Process | Medium |
