Projection Welding Machine

1
What is Projection Welding
Projection welding is a process in which
contacting metal surfaces are joined by the heat
obtained from resistance to electric current.
Work-pieces are held together under pressure
exerted by electrodes

Projection Welding Machine - Advantages

• Large scale reduction in power (Kva) demand.
• Cost of manufacturing electrodes is reduced.
• Negligible blackening and distortion at weld
  joint.
• No effect of normal voltage fluctuation on weld
  quality.
• Welding near heat sensitive parts is possible.
• Welding of similar and dissimilar metals is
  possible.
• Installation and operating cost of the machine
  is very less.
