20 Feb 2013 MMA welding consists of creating a high-intensity electric arc between a shielded metal-cored electrode and the metals to be joined. Oerlikon can provide a 1.2 Manual Metal Arc Welding Process. Arc welding processes uses an electrical power supply to create and maintain an electric arc between an electrode and Manual metal arc welding was first invented in Russia in 1888. It involved a bare metal rod with no flux coating to give a protective gas shield. The development manual metal arc welding process (metal arc weld), the strikes of ionized gas with high resistance in work piece that is generated heat and weld the metal. Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld. Manual Metal Arc (MMA) Welding Aiming for cleaner, high quality welds at lower cost. Manual Metal Arc (MMA) welding is the most flexible and one of the most widely used arc welding processes. It involves striking an arc between a covered metal electrode and a workpiece. Manual metal arc welding (MMAW) or shielded metal arc welding (SMAW) is the oldest and most widely used process being used for fabrication. The arc is MMA welding Manual metal arc (MMA) welding is a welding process where the electric arc burns between a coated electrode and the workpiece. The electrode
