Electric Arc Welding. Arc welding is a fusion welding process used to join metals. The arc can be either manually or mechanically guided along the line of the join, while the.

The weld pool is protected from oxidation by the gasses produced by melting the chemicals on the electrode coating. An arc discharge is an electric discharge phenomenon of a gas and refers to current released in air. An electrode is gripped in the electrode holder. Arc welding for beginners watch now! When the voltage applied to two spatially separated electrodes is gradually increased, the air insulation finally breaks and current flows. Electric arc welding is based on the fact, as electricity passes through a gaseous gap from one electric conductor to another, a very intense and concentrated heat is produced. The majority arc welding machines are ac output. Electric arc welding of metals can involve a great number of health and safety hazards. The welding region is protected by some shielding gas, vapors or slag. Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when the cool result in a binding of the metals. The arc welding technology area focuses on the most commonly used arc welding processes, mainly gmaw/mig, gtaw/tig, smaw/stick, and plasma.
