ABSTRACT:
The seam welding machine with welding arrangement 10 has a lower part (1) and an upper (2). Load-bearing components are upper and lower longitudinal girders (20, 21) with a rigid connection (3, 4) between them. For clamping sheet blanks (7, 8) for welding, two clamping blocks are provided, each with upper and lower pressure beams (24, 25); at least the upper pressure beams (24) can be raised and lowered by means of jacks. For longitudinal transport of workpieces (7, 8) along the weld axis (Z), each beam has a feed unit (40, 41). Each feed unit comprises a longitudinal guide extending in the direction of the axis (Z), a slide, with clamping devices, guided on this longitudinal guide, and a reversible linear drive connected to the slide.
