This is a resistance welding process in which energy is stored in a bank of capacitors by charging to a pre-set voltage and then discharged through a transformer.
As very high current is passed in very short duration of time the resulting weld quality is excellent.
CD Projection Welding Machine is ideally suitable for welding thick material within the shortest period.
It is the best choice for bulk production within consistent quality for manufacture of wide range of products.
As a leading manufacturer of projection welding machines we ensure easy to operate range of machines with customization to meet the needs and demands of the clients.
Advantages:
Voltage fluctuations do not affect the weld quality.
Low Installation and operating cost of the machine.
Significant reduction in power (KVA) demand as compared to conventional resistance welding machines.
Blackening and distortion at weld joint are hardly noticeable leading to excellent aesthetics and leaving almost no mark on the other side of the weld.
‘Welding near heat sensitive parts is possible.
Dissimilar metals welding possible.
Machine can work on Generator set as it is operates on three phase.
Minimum heating of components.
‘Water-cooling not required for electrodes due to very short weld times. Cost of manufacture and maintenance of electrodes and fixtures is reduced considerably.
