TYPES OF ARC WELDING

Shielded metal-arc welding1 accounts for the largest total volume of welding today. In this process an electric arc is struck between the metallic electrode and the workpiece2. Tiny globules of molten metal are transferred from the metal electrode to the weld joint. Arc welding can be done with either alternating or direct current. A holder or clamping device with an insulated handle is used to conduct the welding current to the electrode.

Gas-shielded arc welding3, in which the arc is shielded from the air by an inert gas such as argon or helium, has become increasingly important because it can deposit more material at a higher efficiency and can be readily automated. Either direct or alternating current is used, and filler metal4 is added either hot or cold into the arc. Consumable electrode arc welding5 with a carbon dioxide6 shielding gas is widely used for steel welding. Metal transfer is rapid, and the gas protection ensures7 a tough weld.

Submerged arc welding8 is similar to the above except that the gas shield is replaced with a granulated mineral material as a flux.
