MMA welding is used for joining as well as hardfacing. The Manual Metal Arc welding process uses as consumable electrodes which are coated with flux to create a protective atmoshpere when welding. Because of the simplicity of its equipment and operation, MMA welding is one of the world’s most popular welding processes. 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.
