What we do


Metal joining

We have nearly 200 welding technologies in our range. Many of these involve connecting materials from various material groups, such as the butt welding of carbon steel sheets explosively cladded with titanium.


  • Explosive cladding
  • Weld overlay cladding
  • Liners
  • Phenol heat-cured coatings
  • Aluminium cladding
  • Rubberisation
  • Pickling and passivation
  • Sandblasting and anti-corrosion coating application
  • Painting in industrial and offshore conditions (Class C5)

Heat treatment

We carry out heat treatment of welded joints (PWHT) to reduce and redistribute residual stresses in the material introduced by welding.

We apply heat treatment in furnaces and local heat treatment using resistance annealing machines.

Annealing is carried out by qualified and authorised by the Technical Inspection Authority.
For local processing, we use 6-channel 40 kVA resistance annealing machines, reaching operating temperatures of up to 1050 °C.
