Arc-Welding Processes
Arc-welding includes those welding processes wherein heat required for welding is derived from an arc powered by electrical energy, may be AC of DC as shown in figure1.2. Very high temperatures (up to 30,000'C and more) are obtained in the welding are developed between the tip of electrode and the work piece.
Figure. Arc Welding set up
In arc-welding, the electrodes used may be consumable type or non-consumable type.
Consideration: 1. From above equation, it is clear that centrifugal tension is not dependent of T1 and T2. It depends upon velocity of the belt. For lower belt speed (that is,
