MIG Welding
In MIG welding, a continuous solid wire electrode will be fed through the welding gun into the weld pool, thus joining the two base materials together. To protect the weld pool from contamination, a shielding gas will be sent through the welding gun. MIG stands for metal inert gas and the technical name for it is gas metal arc welding (or GMAW). It is commonly known as wire welding. MIG welding is used to weld rough materials onto base metals and makes it easy to strongly fuse thick materials together. It is a specialized process and can be used on a variety of metals. It is most commonly used on steel.
Advantages
- Clean-up is quite less since there is no covered slag.
- It is an easy process to learn.
- Production cost is cheap.
- All commercially available metals and alloys can be welded.
- Welding is possible in all positions.
- The generated fumes are low.
- Filler compositions and diameters are available in a wide range.
MIG WELDING PARAMETERS
Welding Current and Voltage, Travel Speed of the Arc, Extension of the Electrode, Electrode Size, Gas Flow Rate and Types of shielding gases are the process parameters of MIG welding which define the weld quality.
