Resistance Spot Welding is one of the oldest of the electric welding processes in use by manufacturing industries today.

The welding process is made by a combination of heat, pressure, and time.
It relies on the resistance of the material to be welded, clamped between the electrodes and to current flow that causes a localised heating in the component part.

The electrodes exert the pressure.

The time is how long current flows in the joint. This is determined by a number of factors; including the material thickness, the material resistivity, the current level, and cross-sectional area of the electrode tips and contact surfaces.

Process control is key to achieving repeatable and reliable joints, for advice contact us
