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.
