MMA Welding Details:
MMA welding (metal arc) does not require shielding gas; protection for the weld pool comes from the electrode cover which melts during welding, and forms a protective layer of slag on the weld pool. When the welding is completed and the layer of slag is removed, the finished weld will be disvocered underneath.
MMA welding is the oldest and still the most commonly used arc welding process, although the proportion of MMA use is decreasing as gas-shiedled welding process is becoming more popular.
MMA welding is, however, an irreplacable method for instace when welding outside in windy conditions where using shiedling gas would be difficult. Another important benefit is that electrodes can be bought everywhere, also in small package.
