What is consumable wire resistance seam welding? - TWI

Consumable wire resistance welding is a variant of resistance seam welding in which the electrode wheel is grooved so that a shaped copper wire can be introduced between the wheel and the work. The wire is fed continuously from a spool, passes around the electrode at welding speed, completes a length of weld and is then discharged to a scrap ...

Resistance Welding Overview

Resistance welding is a welding technology widely used in manufacturing industry for joining metal sheets and components. The weld is made by conducting a strong current through the metal combination to heat up and finally melt the metals at localized point(s) predetermined by the design of the electrodes and/or the workpieces to be welded.

What is Resistance Welding : RWMA : American Welding Society

What is Resistance Welding. Resistance welding is the joining of metals by applying pressure and passing current for a length of time through the metal area which is to be joined. The key advantage of resistance welding is that no other materials are needed to create the bond, which makes this process extremely cost effective.
