Wire Compacting is a very common resistance welding technique, which is commonly used in automotive applications where stranded wire needs to be joined to another component.
Resistance welding stranded wire to other components offers many challenges, so it is beneficial to have it compacted first. Compacting applications are ideally suited to a high frequency inverter welder with their closed loop feedback functionality. The enables repeatability even when there are variables with the stranded wire.
Either a compacting unit or jigs and fixtures accompanied with a high force weld head are ideal for this application.
