Our long lasting experience in welding deserves special attention. We execute technically advanced welded structures with very diversified overall dimensions and weight reaching 30 t.
We have authorizations for welding works under DIN 18800 T7 and DIN 15018 /cranes/ granted by SLV, and authorizations granted by Technical Inspection Office (UDT) for producing cranes elements and repairing cranes and overhead cranes.
We offer welding of constructional steels in full range of strength from ordinary low-carbon steels to fine-grained high-strength steels type S1100QL.
We also execute welding of aluminium structures according to Welding Certificate EN1090-3 EXC4.
We apply welding methods:
— semi-automatic MIG-welding and MAG-welding, using solid and flux-cored wires
— automatic hidden arc welding
— covered electrodes manual arc welding
We have suitable instrumentation enabling welding of large-size structures in best positions. We provide welded joints inspections: liquid-penetrant inspection, magnetic particle inspection, radiographic inspection and ultrasonic testing.
We employ experienced welders authorized under EN-287–1. Welding tests we carry out in our welding laboratory likewise we work out welding instructions (WPS).
