MMA Welding



Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc weldingor informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.

Because of the versatility of the process and the simplicity of its equipment and operation, shielded metal arc welding is one of the world’s first and most popular welding processes. It dominates other welding processes in the maintenance and repair industry, and though flux-cored arc welding is growing in popularity, SMAW continues to be used extensively in the construction of heavy steel structures and in industrial fabrication. The process is used primarily to weld iron and steels (including stainless steel) but aluminium, nickel and copper alloys can also be welded with this method.
