welding with fuse agent - ARC welding method

Welding processes:


CGH Polska is among a few tank manufacturers in Europe employing the approved welding technologies for austenitic (stainless) steels with fusing agent, the method 121. In addition, we use approved technologies of welding low carbon steels for application at -50oC, by following methods: fuse agent – method 121, MIG-MAG – method 135, TIG – method 141.

Our strength is offering top quality products manufactured in state of the art process:

  • Automatic production line by Heinrichglück, which guarantees perfect assembly.
  • Inner and outer joints shielded arc welded, using top quality welding materials.
  • Cleaning of surface to Sa 2,5 cleanness grade acc. to ISO 8501-1
  • Automatic application of Endopren outer insulation
  • NDEs of welded joints and tightness tests of outer layer with the test voltage of 10 kV
