Performance and Procedures

Keyhole plasma arc welding

We implement all welding processes (circular and longitudinal seam welding) using state-of-the-art devices ensuring top quality and highest reliability. We work with WIG and MAG welding devices, a plasma welding apparatus and are certified for the following welding methods:

  • Welding procedure test according to DGR 97/23/EC, DIN EN 288-3, AD 2000 Bulletin HP 2/1 (WIG/MAG)
  • Welding procedure test according to DGR 97/23/EC, DIN EN 288-3 (plasma keyhole)

Our SAF-Oerlikon welding apparatus consists of a mobile apparatus support provided with a roller bracket rotating device, a longitudinal seam welder, a plasma welding machine and a video system for monitoring the welding process.
