Welding 1

Arc Welding - Shielded metal arc welding (SMAW), also known as stick welding, is a manual arc welding process that uses a consumable electrode coated in flux to lay the weld. An electric current, in the form of either alternating current or direct current (DC+ or DC-) from a welding power supply, is used to form an electric arc between the electrode and the metals to be joined. As the weld is laid, the flux coating of the electrode disintegrates (Burns), giving off vapors that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination.

Oxy Welding - Oxy-fuel welding, commonly called oxyacetylene welding, oxy welding, or gas welding in the U.S., is a process that uses fuel gases and oxygen to weld metals.

Oxy Cutting - Oxy-fuel cutting is a process that s fuel gases and oxygen to cut metals.

Metal Sheers - A power shear is electrically, pneumatically, or hydraulically powered tool designed to blank large pieces of metal. They are designed to cut straight lines.
