arc welding basics and types of arc welding

arc welding basics and its definition Arc welding process that uses the arc discharge for the heat source is widely used in the world. And the most popular welding process that has been used from the old time is shielded metal arc welding (SMAW). As shown in the above picture, the voltage applied across the core rod of the electrode and the base metal generate an arc. The arc temperature for SMAW is about 5,000 – 6,000 K. This arc heat generate molted droplets of electrode tip that transfer to the weld pool. There is a voltage gap between the[…]
