Resistance Welders
Used for a wide range of automotive, aerospace and industrial applications, resistance welders join metals by applying pressure and passing current through the metal area being joined for a specified length of time. This is extremely cost effective because no other materials are needed to create the bond. Spot, seam, projection, flash and upset welding are separate resistance welding processes that use different types and shapes of weld electrodes to apply the pressure and conduct the current. The electrodes are cooled by water flowing through them and the other conductive tooling of the resistance welding machine.
The New Generation of Resistance Welding: Not Your Father’s Process
Resistance welding is a sub-specialty in the world of metal joining that was often ignored and taken for granted in the past, but not anymore: so many exciting new process technology developments are now taking place in this field that shops are trying to keep up so they can capitalize on the new business opportunities being created.

This simple drop-probe device is designed to prevent a press-type resistance welder from cycling if it encounters fingers in the point-of-operation area, therefore preventing contact between the operator and dangerous moving parts.
Cavities in the solder between the electrode and the shaft have a negative impact on the quality of the resistance weld. Plansee explains why anyone wishing to avoid cavities should use cast electrodes rather than soldered electrodes.
Brian Moore of Bosch Rexroth explains how adaptive control can help reduce losses related to poorly made resistance welds, increase resistance welding throughput and elevate your control of automated welding processes to a whole new level.
Georg Fischer Automotive uses an innovative resistance spot-welding process from Fronius to join die-cast aluminium parts in the vehicle door-frame on the Porsche Panamera.
Amada Miyachi America’s compact MM-410A supports process development and production applications for resistance welding technologies including AC, DC inverter, AC inverter, transistor, and capacitive discharge. Data storage is available using an onboard flash drive.
