Product Questions
Share the material, cross-section, end geometry, finished-joint requirement, production rate and available clamping length.
Tube and profile applications can be reviewed when the section can be clamped and heated uniformly.
Jaw geometry is based on the workpiece section, surface condition, gripping length and upset force.
Some combinations may be feasible, but they require application-specific validation and should not be selected from capacity alone.
FB Series
Resistance Seam Welding Machines
The FB series combines resistance welding power with driven wheel electrodes for continuous or indexed seams in sheet-metal components.
