Seamlessly Joined? Comparing Cast and Soldered Electrodes for Spot Welding

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.

What You Must Know About Adaptive Control of Resistance Welding

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.

Resistance Spot Welding of Aluminum Moves to Production Line

On each vehicle door, the professionals at GF weld 16 spots, each exactly 5 mm in diameter, in an approximately 100 sec cycle. (first view)
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.


When unintended resistance is introduced into the welding circuit, it can lead to equipment failure, poor weld quality, porosity, the inability to weld to specification and the frustration of trying to diagnose an intermittent problem. Here?s how to prevent it from happening.
