Spot Cum Projection Welding Machine

Projection welding is a form of resistance welding which uses pressure and electrical current to join two or more metal parts that have been designed to meet at one or more specific points with the maximum amount of contact. This allows for more efficient welding with less energy and greater weld strength.Automatic welding is defined as welding operations where all parameters are pre-set and cannot be adjusted during welding. • Mechanised welding is where all of the activities are performed automatically but the welding variables can be changed during welding.
