Welding

The company welds using the MAG (135, 136) process. We employ more than 70 in-house licensed welders with valid DIN EN 287-1 certificates. Our company has acquired a welding certificate SIST EN ISO 3834-2, wich defines the quality requirements for fusion welding of metalic materials.


 
We mostly weld construction materials of classes S235, S275, S355, S460 and fine grain steel microalloys S690 and S960.

We have also required welding certificates SIST EN 1090-1 and SIST EN 1090-2, which regulate the fabrication and assembly of steel structures.

Welds are controlled with various non-destructive methods (ultrasonic, magnetic and penetrant control). All controllers are certified in accordance with standard DIN EN 473:2006 (UT 2, MT2,…).

Three employed welding controllers have completed specialist international welding engineer training (IWE) in accordance with EN ISO 14731.
