Welding plant for rolled sheet metal pipe has welding device provided by work head mounted on traverse extending above machine bed

摘要

The welding plant has a machine bed (4) with uprights (5) at the corners, along which the rolled sheet metal pipe (2) is displaced in the longitudinal direction, for welding the longitudinal pipe seam via a welding device (12), positioned between 2 rolling devices (11) of a vertically displaced work head (10), mounted on a traverse (9) above the machine bed. Each rolling device has at least 2 adjacent wheels pivoted in common about a rotation point along the central longitudinal axis (16) via a pivot device.
