FIELD: metallurgy.
SUBSTANCE: welding cage contains iron ring, in the basis of which there are installed in cases top, side and centre roll cartridges with adjuster of its movement, top pinch roller with displacement mechanism in the form of drive joint screw-nut, supporting rollers and welding unit. In area before welding on guidelines of case of each roll cartridge there are located inner roll cartridges, pivotally connected to position adjusting mechanism, each of them is mounted on detachable support, fixed on case of roll cartridge. Parallel to top pinch roller it is located additional pinch roller with its dislocation mechanism in the form of hydrocylinder. Both pinch rollers are mounted in common case.
EFFECT: improvement of welded pipes ensured by alignment registration of welded edges.
