Prospot are able to supply a range of Seam welding machines. All of the AUTOFORGE range of rocker arm spot welders can be fitted with variable speed motorised seam welding attachments for both circumferential and longitudinal seam welding, either upper or lower driven. They are are fitted with twin foot pedals with a HIGH-LIFT facility for improving welding access and speed of production.
All machines have water cooled electrodes, holders, timers and transformers. Each machine is fitted with telescopic arms enabling the machine throat to be easily adjusted without removal from the machine, provision is made for both electrode holders to be set at an angle of 20 degrees from the vertical if required.
All machines can be fitted with either a standard multi program digital timer or a more sophisticated welding control with constant current control and other features.

Resistance seam welding is a variant of the basic resistance spot welding process. In spot welding a weld nugget is produced by passing an electric current through the sheet materials to be welded while they are held together under a mechanical force between shaped copper electrodes in a lap configuration. Fusion is produced where the sheet surfaces are in contact because this is the point of highest electrical resistance and hence the point where the temperature is highest.
In seam welding a series of overlapping nuggets is produced, usually by replacing the conventional spot welding electrodes by wheels that turn as the parts to be welded are fed between them. The process thus produces a continuous leak-tight seam.
