Digital welding
PERFECT arc®
PERFECT arc® is a digital welding process developed by SMS group offering great potential in energy saving. That’s because the digital current source secures precise power supply control, which leads to energy cost reductions of more than 30 % compared to conventional welding techniques. Equally suitable for arc and submerged-arc welding, the solution stands synonymously for perfect weld seam and pipe quality.
Benefits
- A ‘perfect arc’ that reacts fast and can be precisely controlled at any time thanks to a fully digitalized current source instead of thyristor current sources
- 50 % quicker with tack welding and 20 % faster with submerged-arc welding
- Energy costs can be reduced by more than 30 %
- Electric efficiency ≥90 % with uniform load on the electricity network
