We specialize in titanium welding.
Titanium welding! Most of the time we work with homogeneous material, which is often both the best and most economically advantageous. Sometimes, however, other solutions are required, such as explosive bonding or loose lining, where a vessel is lined with a thin sheet of titanium. Titanium is difficult to weld and requires special skills and protected environments as the material changes if it comes into contact with oxygen during welding.
We weld according to standard EN ISO 3834-2 and all Örnalp Unozon welders are licensed to ensure a high and consistent quality of work.
