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.

RESISTANCE: THE UNKNOWN WELDING VARIABLE

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.

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. 

Advanced Spot/Projection Welder

Booth N-18025: The deep throat depth of the MFDC Spot/Projection Welder from Dengensha America uses advanced controls, precise welding currents and better heat efficiency to reach maximum current levels faster and create stronger welds for larger high strength steel parts.
Dengensha showcases their new MFDC Spot/Projection Welder that reaches maximum current levels faster and creates stronger welds for larger high strength steel parts.

Precision Linear Resistance Spot Welding for Automated High Speed Micro Welding

DC613T and DC1013T units have a 5 percent duty rating and realize further production control advantages through the high connectivity TCP/IP, USB, PLC and RS232 interfacing ports and support for direct connection of devices such as cameras, keyboards and USB data sticks.
DC613T and DC1013T linear DC resistance spot welders from MacGregor Welding Systems use a high duty, high power linear transistor bank that delivers a programmed pure DC current to within 1 percent accuracy.
