MMA welding – welding services
MMA welding (Manual Metal Arc Welding) is the oldest and most versatile arc welding method.
Manual metal arc (MMA) welding is a welding process where the electric arc burns between a coated electrode and the work piece. During welding the electrode is fixed in a holder and touches shortly the area that is to be joined. The obtained high quality weld features with good mechanical properties. MMA method may be used in case of components as thin as 1,5mm and thicker ones.
Coated electrode arc welding may be provided at any position and any location– at the height, under water surface and in the open (if not exposed to strong wind gusts).
MMA is the method employed for welding of non-alloy steels and alloy steels, as well as cast iron, nickel, copper and its alloys.
