Q: Which material is suitable for resistance welding?
A: Resistance Welding includes Resistance Spot Welding (RSW), Resistance Seam Welding (RSEW), and Projection Welding (PW). Resistance welding uses the application of electric current and mechanical pressure to create a weld between two pieces of metal. Weld electrodes conduct the electric current to the two pieces of metal as they are forged together.
Tungsten copper, tungsten and molybdenum are chosen for this application for their certain properties.
