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.

FABTECH 2016 Sneak Preview: Welding

Booth N-3904: The new Robacta Drive TPS/i push-pull robotic welding torch from Fronius features an unprecedentedly compact design, impressive cost effectiveness, and significantly enhanced mechanics that further improve component accessibility and TCP precision so that even more welding tasks can now be performed profitably by robots.
The 2016 edition of FABTECH is on track to be one of the largest metal fabrication events ever at the Las Vegas Convention Center in Las Vegas from November 16-18. This special sneak peek provides technical reviews of some of the equipment, power sources, positioners, systems and accessories that will be exhibited in the Welding Pavilion to help you get a head start on navigating the show floor and managing your time while you’re there.

Simultaneous Workpiece Movement and Weld Nut Feeding

The Upper Electrode Feeder Unit from Dengensha America reduces weld cycle times while promoting faster feed rates through simultaneous workpiece movement and weld nut feeding. Its patented new linkage design incorporates linear as well as rotary motion to feed nuts accurately at high speed.
The Upper Electrode Feeder Unit from Dengensha America reduces weld cycle times with faster feed rates and reduced part positioning that better secures each part.

Breakthrough Flexwave Welder Capacitor Discharge Technology

Flexwave Welders and technology combine the capabilities and benefits of a Capacitive Discharge Welder (CDW) and a 15,000 Hz Bipolar Medium Frequency Converter (MFC) to provide a direct current configuration of weld current values for easy setting of parameters. They also maximize waveform flexibility to allow necessary parameter settings, such as tempering, demagnetization, upslope, etc. and provide users of single-phase AC welders the option of replacing their existing controller unit with a Flexwave Welder controller, which enables a shop to use it as a Flexwave welder as well.
Flexwave Resistance Welder and corresponding flexible waveform technology from Dengensha America produces better quality parts, optimum weld nugget quality, weld parameters that are easier to set, and energy savings.
