Flash welding is a type of resistance welding that does not use any filler metals. The pieces of metal to be welded are set apart at a predetermined distance based on material thickness, material composition, and desired properties of the finished weld. Current is applied to the metal, and the gap between the two pieces creates resistance and produces the arc required to melt the metal. Once the pieces of metal reach the proper temperature, they are pressed together, effect… WebFlash (butt) welding is an electrical resistance welding processes used for joining components, where the energy transfer is provided primarily by the resistance heat from … WebWith butt welding, spring pressure is applied before current begins to flow, destroying the molten zones as they are formed. In flash welding, spring pressure is applied at the end of the weld cycle, after the flowing current has had time to heat up the blade ends. ipcc buch
