Arc Welding | weldingofwelders
Introduction. Arc welding is a method of joining two or more metal parts together by using an electric arc to heat the surfaces to be joined. The electric arc is created between an electrode and the workpiece, which melts the metal and forms a weld pool. The weld pool solidifies as the metal cools, creating a strong bond between the parts.

Arc welding types and principles
Arc welding is welding using the heat of an arc as a heat source. In arc welding, positive voltage is applied to the electrode (welding rod/wire) and negative voltage is applied to the base material. This makes an arc occur from the base material to the electrode. The output current of the arc is about 5 to 1,000 A and the output voltage is ...
