Automatic Longitudinal Seam Welder is a process used to produce linear welds on a wide variety of parts. For many industrial applications it is necessary to form the material into a desired shape, e.g. a cylinder or rectangular tube, and then weld the edges to form a rigid structure. The traditional method of doing this is to manually hold the edges in alignment, tack weld them and then complete the linear weld. This is done manually or by use of a simple carriage carrying the welding torch.  This type of procedure is costly and time consuming.
Schroeder longitudinal seam welders provide a solution to these problems. They optimize the welding process, reduce welding costs and improve the quality of the weld. They are designed for the straight line welding of all weldable materials in thicknesses varying from 0.1 mm to 10 mm. Thicker materials can be accommodated using Schroeder's unique mandrel adjustment capability.

Function
Adopt key pressure structure. Equal stable clamping and cooling effect. Crossbeam and welding cart supply precise welding. Used for high quality and low deformation longitudinal beam welding.In most cases, butt joint design welding seam.
Welding modes: GTAW , PAW, GMAW, FCAW, SAW, YAG.
One side welding and both sides forming.
