WELDING ELECTRODES LAST TEN TIMES LONGER
A manufacturer of switchgears tested TZM back cast electrodes from Plansee SE (Österreich, Austria) for resistance welding and discovered that, due to the seamless joint with the electrode holder, these back cast electrodes have a substantially longer service life than their soldered alternative. Until now this switchgear manufacturer had used soldered electrodes to combine silver contacts with brass or copper. In this process an electrode could weld around 5,000 spots before it had to be reworked or even changed. Plansee thought this result was far too low and recommended the customer to check out their back cast TZM electrodes.

In the first results that were received, the back casted electrodes managed to weld as many as 50,000 points at about 120 welding points per minute before being reworked for further use. In other words, these back cast electrodes lasted a remarkable ten times longer. In contrast to soldered electrodes, the back cast version provides constant thermal conductivity as well as constant electrical resistance of the electrode from the seamless joint that runs between the TZM electrode and the electrode holder, which is made out of copper. The better this joint is, the longer the service life of an electrode is and the more reproducible the welding results get.

SPOT WELDING OF NON-FERROUS AND NON-METALLIC FLAT MATERIALS
With the move toward lightweight materials, OEMs are looking for the most effective way to cut weight without sacrificing quality or safety. Existing technologies needed to process these lighter materials typically add weight or cost, result in low weld strength, or have porosity defects. But the SpotMeld™ friction spot welding system from Coldwater Machine Company (Coldwater, OH) overcomes these issues and is efficient enough to run in a production environment.

Based on Refill Friction Stir Spot Weld (RFSSW) technology, this system spot welds aluminum (1000 – 7000 series), magnesium, non-ferrous and dissimilar sheet materials as an alternative to single-point joining processes like resistance spot welding, laser welding and riveting. SpotMeld friction stir spot welders can be configured to application specifics and mounted on any industrial robot. A variety of weld recipes can be used on demand by the robot controller, which results in a very flexible production system.

Relying on RFSSW technology, the SpotMeld system uses rotational friction to heat the materials along with pressure to forge together the parts using wear-resistant tooling to join two or more surfaces. Basically, heat is generated between the tool and material, creating a soft region. Pressure is then applied, resulting in a solid state joint. In addition to its ability to join dissimilar and lightweight materials, benefits include high quality joints with a small heat affected zone, consistency in weld duplication and faster weld times, as well as being environmentally cleaner and safer with no filler material, spatter, smoke, radiation or shield gasses.
