What is Arc Welding?

Manual metal arc welding is one of the world’s most popular welding processes because of the versatility of the process and the simplicity of its equipment and operation.

Also known as stick welding, Arc welding uses electrodes coated in flux to lay the weld by an electric current – either alternating current (AC) or direct current (DC) – from a welding power supply, to form an electric arc between the electrode and the metals to be welded together.

As the weld is laid, the flux coating of the electrode disintegrates, giving off vapours that serve as a shielding gas and providing a layer of slag to weld (primarily) iron and steels, including stainless steel.

Arc Welding dominates other welding processes in the maintenance and repair industry; it is also used extensively in the construction of steel structures and in industrial fabrication.
