  • The welding processes are based on welding procedure tests carried out in accordance with DIN EN ISO 15614-1

Semi-automatic TIG welding

  • Welding the longitudinal seams of the sleeves with and without filler metal

TIG welding

  • Fillet welding – metal bellows / flange with filler metal

MIG/MAG-welding

  • Make a welded joint between the oval flanged disk and pipe nozzle

MAG welding

  • Welding bracing parts to the expansion joints

Resistance seam welding

  • Overlapping welding is carried out on sheets of 0.6-3mm thickness
  • Primary application in the low pressure area

Orbital welding

  • for butt welds and flanged seams
  • mainly used for standardised welding seams for large quantities
