Assembly and welding
- 2 Messer acetylene cutting machines:
- thickness range: from 2 to 300 mm
- bench size: 3500 x 12000 mm
- Metal sheet rolling on rollers
- B-9 and B-28 rollers
- maximum sheet metal thickness: 10–25 mm
- maximum sheet metal width: 2000–3000 mm
- minimum coiling diameter: 270–600 mm
Welded structures manufactured:
- stator frames
- bottom and top trusses
- pressure segments
- end shields
We undertake welding processes using the following methods:
- 135: MAG–semi-automatic with active gas shielding
- 141: TIG–tungsten electrode in inert gas
- 111: MMA–manual arc with coated electrodes
Overall dimensions of the welded structures:
- max. dimension of a single unit: 12 m x 4.1 m x 3.7 m - max. weight: 32 t.
- max. dimension of a single unit: 12 m x 6.2 m x 4.0 m - max. weight: 100 t.
- max. dimension of welded construction after assembly 16 m x 16 m x 6 m - max. weight: 100 t.
Our welding shop is equipped with:
- cranes with hoisting capacity up to 32 t
- cranes with hoisting capacity up to 100 t
- workshop cranes with lifting capacity up to 1 tonne,
- a travelling mobile platform with maximum working height up to 6 m.
We possess the following welding certificates:
- quality requirements for welded metal materials according to EN ISO 3834-2
- authorising welding of structural steel components to EN 1090-2 class EXC4
As part of the removal of welding stresses process, we offer a vibration stabilisation process. This is a cost-effective alternative to heat treatment. We have a self-calibrating vibrating device which automatically generates a stabilisation report. We can vibrate structures ranging from 0.1 to 40 tonnes.
