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.
Hermetic Seam Sealing Enables Reliable Welds and Protects Electronic Devices from Harsh Environments
A primer on the two processes – parallel gap resistance seam welding or opposed electrode projection resistance welding – you can use to win customers in the highly demanding aerospace, industrial 5G commercial communications, medical device, and military electronic industries.

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.
Amada Weld Tech recently introduced a redesigned wire compacting unit for its line of modular resistance welders. Well suited for stranded wires, the plug-and-play, ready-to-install modular compacting unit provides precise, fast, and reproducible adjustment after electrode exchange.
Weld Systems Integrators’ next generation of capacitive discharge (CD) welders monitors force in real time to ensure consistent-quality results. Throat depth provides room for automation options such as end effectors and fastener feeders.
Taylor-Winfield Technologies’ linear friction welders use solid-state bond welding to join parts of the same or different material in various geometries. Operators can adjust frequency and amplitude during the process.
