Welding proces has a very long tradition at ZVUS. Most modern methods of welding are used at given industry section. Currently some projects are welded in thickness 3 – 220 mm and materials are from common carbon steel, through stainless materials to the special materials as the titan is.
Most widespread methods at ZVUS are submerged arc welding (SAW), which is very efficient and embody a minimum of defects at weld bead.
Other methods, which are at ZVUS enhanced, are welding by PAW (Plasma arc) method and mechanical welding of join tube-tubesheet at heat exchangers.
As one of the few manufacturers, we are able to machine weld stainless weld deposit on the carbon steel parts of vessels (bottoms, heads, shells).
