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

Implementing new technologies and new investments complement the entire technological process, in order to fully meet customer expectations. In response to ever increasing market demand and to meet ever more restrictive quality requirements concerning application of inner and outer paint coats of steel tanks, CGH Polska has carried out new projects in this area.

CGH offers products complying with more and more restrictive environmental standards. We continuously modify our production process to meet the most restrictive standards in the area. The example is deodorization system in the paint shop and in the tank seasoning room.

New spray booth, working area of 5 x 5 x 20 m, enables application of paint coat in tanks up to dia. 2900 mm.
