What is Arc Welding? How Arc Welding Works? – The …

The process of joining metal to metal with the help of an electric arc is called arc welding. In this welding process, the arc is used to create intense heat and this heat is used to join the metals together. The arc is brought in between two metal pieces and due to the heat generated, the metals melt and when it cools a strong welded joint is formed. The power source used in arc welding is electricity (electric current). …
