Plant for automatic argon-arc welding “USK-2500R” is made for welding of circumferential seams.
On the frame rails of the plant “ USK-2500R” is a lunette moving along the rails. The spindle of the rotator is hollow, that provides argon flow to protect the weld bottom run. Tailstock with spring-loaded movable sleeve serves to tightening welded nodes to the pipe when weld is shrinking.
Welding head “ASGV-4ARC” is located on the carriage, movable on the guide beam in parallel to the plant frame. Mechanisms of the welding head equipped with modern servo drives with “MITSUBISHI ELECTRIC” motors.
Also the plant is equipped with a mechanism of linear movement (length of 3000 mm), electric gear cabin, operator control panel, gas block, universal rectifier for welding with non-consumable electrode “VSVU-400” and gas and electricity wires.
