Linear Seam Welding Systems

Arc seam welders are used for this mainstream manufacturing process, which is used to produce high quality welded seams with 100 percent penetration. The seams that are welded in standard machines are usually straight and flat. Applications include flat sheets, cylinders, cones, and boxes.

Ferrous and non-ferrous alloys can be welded using a variety of arc welding processes. The design of the automatic welder machine (seam welder) allows the weld seam to be clamped firmly between copper fingers and a copper backing bar. (material’s other than copper can be used).

Bancroft Engineering offers customized seam welders equipped with a variety of automated processes such as TIG, Plasma Welding (PAW), Submerged Arc or MIG welding.
