"USK-22MK" plantn is designed for automatic argon arc welding of circumferential welds of pipes, pipelines, rods, struts made of anti-corrosion heat-resistant structural steels and alloys in an inert gas environment with or without a filler wire with a non-consumable electrode.
The installation allows welding of butt joints of bodies of rotation in the lower position and welding of corner, T-joints and overlap joints of bodies of revolution by tilting the welding head at an angle of ±45°.

Diameters of welded products with a horizontal axis of rotation at different positions of the head relative to the vertical, mm:
- The head is located vertically – 20-450;
- The head is rotated 45° counterclockwise – 400-700;
- The head is rotated 45° clockwise - 100-400.
