Linear Seam Welders (SEAMER)

Longitudinal seam welding can be used to produce gas or fluid-tight joints in a variety of sheet metal fabrications. Sheets can be tubular, formed rectangular/square tubes or flat sheets with a longitudinal seam welder for manufacturing parts like tin cans or steel drums. Steel, aluminum or stainless fuel tanks for motor vehicles are other prime examples.


Bancroft Engineering’s linear seam welders are designed for straight line welding of all weldable metals in thicknesses ranging from 0.005” to 0.500” and lengths in excess of 20 feet with up to 100% penetration.
