Plant for welding in a controlled medium “USKS-27”

Appointment


Plant for welding in a controlled operating medium “USKS-27” is designed for automatic and manual arc welding with non-consumable electrode in a controlled medium of circumferential and longitudinal seams of parts made of reactive metals and alloys, mounted on the chuck plate of the rotator, with the filler wire or without it.


Maximum diameter of the welded products is 800 mm, maximum height is 800 mm, maximum weight of the welded product is 250 kg.


Plant allows to weld butt, tee, lap joints of solids of revolution with a horizontal axis of rotation at different positions of the welding head in automatic mode - from vertical to deployed at an angle of ±45° from the vertical.


When setting the axis of rotation in the vertical position, it is possible to carry out welding of edge connections of solids of revolution in the vertical position of the head. It is able to produce welding to the body elements of bends, fittings, connections, brackets, etc. by manual welding burners at 150 A and 400 A.


In automatic mode, the welding of the connections may be produced by oscillation of the electrode or without is. Welding butt joints can be made with automatic maintenance of a predetermined value of the arc gap.
