MMA

What is MMA in welding machine?

Manual metal arc welding (MMA or MMAW), also known as shielded metal arc welding (SMAW), flux shielded arc welding or stick welding, is a process using an electric current flowing from a gap between the metal and the arc-welding electrode. The stick is effective for welding most alloys or joints and can be used indoors and outdoors or in drafty areas. It's also the most economical method and provides the ability to create a good bond on rusty or dirty metals. Manual metal arc welding was first invented in Russia in 1888.

Advantages of MMA

Better suited for windy, outdoor conditions

More forgiving when welding on dirty or rusty metal

Works well on thicker materials

STICK WELDING ELECTRODE

What is the stick welding electrode?

A welding electrode is a fixed-length, straight welding wire coated with a filler material. The welding electrode has a fixing head with which it is attached to the electrode holder. The other end of the electrode has the ignition head with which the workpiece is stuck to ignite the arc. The quality or trade name of the electrode is indicated near the fixing head in the coating. The diameter of a welding electrode refers to the diameter of the metal rod inside the electrode. The purpose of the coating on the surface of the metal rod is to protect the welding event from the effects of the surrounding air, to produce slag to support the weld, and to make the creation of the arc easier.

MMA WELDING TIPS

Before Welding

Before welding, we have to check the condition of the welding power source, the cables, electrode holder, and the grounding clamp. The quality and strength of the welding electrodes must be checked and they must match the workpiece. The coating on the electrode must be intact.

MMA WELDING TIPS

During Welding

The welding is started by sharply striking the bottom of the groove with the welding electrode. After this, move the welding electrode back to the beginning without stretching the arc, and move the electrode easily while monitoring the width of the molten weld pool. Move the welding electrode with the handle pointing forward. The boundary of the slag formed is visible after the molten weld. It must be behind the molten weld. The distance of the slag boundary from the molten weld can be adjusted with the welding current and the angle of the electrode holder. Throughout the welding, concentrate on the length of the arc and keep it as short as possible. The length of the arc increases easily as the electrode decreases in size during the welding. The movement may be somewhat difficult to control at first but it is easy to get accustomed to. When the welding electrode runs out, one needs to remove the slag from the previous weld and clean it with a steel brush. Ignite the next electrode slightly ahead of the previous weld and then move the welding electrode back to the previous weld and continue with the welding.
