The task for this application was to weld copper stranded wire to a brass ring. This was successfully done with the NRW-IN400PA High Frequency Inverter Welder. This welder utilised its closed loop feedback to monitor and adjust the current waveform during the weld.

After the test we carried out a tensile test to determine if the weld strength met the requirements. In the image you will see the wire failed before the join, indicating the weld was successful.

As normal practice we carry out destructive testing on all our samples to determine if the weld was successful.
