In this resistance welding process, a bank of capacitors is charged to a pre-set voltage and then discharged through a pulse transformer. Very high current is passed in very short time resulting in fantastic projection welding quality. As the machine requires power just for charging the bank of capacitors, the power (Kva) requirement is negligible as compared to any other process of resistance welding. This results in great saving of connected load as well as power usage. As the weld time is very less (ideally 3 to 12 milliseconds), there is negligible heating or blackening of welded components and water cooling for the electrodes is not required. 

This technology is ideal for projections welding, dissimilar metal welding and thin sheet spot welding. Machine users requiring excellent aesthetics, high regard for power saving and consistency in projection welding should adopt this technology. 

Machine Control - Important Features


Projection Welding

Projection welding is a resistance welding process. Projections are made on any one of the components before welding. The weld area and location is defined before welding in projection welding unlike in spot welding where weld area depends on the shape of the electrodes. After passing the weld current for specific time, the projection collapses under the electrode pressure and the parts are welded together. 

The advantages of projection welding are that multiple projections can be welded in one shot, flat electrodes are required for welding, minimum dents and marks after welding etc.
