Longitudinal Seam Welders - External, Internal, Flat Plate and Elevating

Seam welders produce a linear weld across a longitudinal seam such as two flat plates or a tubular pipe. Using pneumatically controlled chrome plated copper clamps to hold up to 3/4" thick material, the seam welder firmly clamps the material for precise alignment of the work piece without the need to tack weld. The welding carriage then carries the welding head down the length of the seam; producing a consistent and high quality weld. Water-cooled back-up bars are available with or without gas purge for use in various weld processes such as Submerged Arc, MIG, TIG and Plasma.
