Electroslag welding

NKMZ keeps leading position in development and application of electroslag welding techniques and procedures (ESW), enabling to produce the parts with weight up to 300 t out of forgings and castings, and also of rolled plate and combined blanks.

Mechanical properties of the joints are as goods as those of the base metal.

If necessary, the elements made of extra strong steel are welded in the most stressed zones of the structure.

Electroslag welding techniques and equipment enable to weld up the parts with section of 4500 х 5500 mm (thickness of weld elements х vertical length of the joints).
