Abstract
A method of welding aluminum to aluminum by thermal resistance welding, providing good electrical and mechanical characteristics. The method uses special electrodes for thermal heat that are hard and have a high electrical resistance, such as molybdenum or tungsten alloy and also relies on the aluminum oxide coating on the aluminum to provide the desired resistance heating of the aluminum to cause welding of the aluminum material. The machine disclosed provides a means for securing aluminum leads to the start and finish end of an aluminum winding automatically and simultaneously.
