Arc Welding How To Do It. 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 started by touching the electrode momentarily against the work to complete the electrical circuit before raising the electrode to establish the arc.
Upon cooling and solidification a metallurgical bond is created. About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy Safety How YouTube works Test new features. Before striking an arc hold the rod about an inch above the base metal and tilt it in the direction of the weld.
By applying intense heat metal at the joint between two parts is melted and caused to intermix - directly or more commonly with an intermediate molten filler metal.

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 electric arc is glowing electrical discharge among two electrodes using ionized gas.
