As a welder, choosing the right type of weld determines your weld's integrity, depending on many factors like the type of workpiece metal, thickness of metal, welding wire, the equipment, and the right technique used in the process of welding.

MIG welding is the most common welding process out of many welding processes that offer a clean weld and easy to learn for many beginners.

MIG welding is also a good alternative for your fabrication maintenance and repair needs.

The technical name for it is Gas Metal Arc Welding (or GMAW) also know as MIG (Metal Inert Gas) welding is an arc welding process in which a solid MIG wire electrode is passed through a welding gun to create an arc into the weld pool, causing the two base materials to heat, melt, and fuse.

The welding gun protects the weld pool from atmospheric contamination by spraying shielding gas. Common shielding gases used are CO2 apart from argon or argon-helium gases. The welding machine is used through a DC (Direct Current) voltage machine.

The whole welding process can be semi-automatic or automatic. A constant voltage, the direct current power source, is most commonly used with GMAW, but regular current systems, as well as alternating current, can be used.

Here are some advantages to MIG welding:

  • Offers ability to join a wide range of metals and thicknesses
  • All-position welding capability
  • Provides a good weld bead
  • Has a minimum of weld splatter
  • Easy to learn the process

Applications of MIG welding:

  • Industrial sheet metal welding.
  • Deep groove welding

Manufacturing Industry: Due to the ease of use of MIG welding, it shows high productivity, which leads to higher profits as it welds metals rapidly and is highly economical.

They are used in the fabrication of pressure vessels and steel structures.

Automotive industry & home improvement industry: Repairs can be done on several different vehicles, whether they are light, heavy, small or large in weight or size, MIG weld creates a dependable and a strong weld even down to 0.5mm, for repair and rebuilding, dismantling, and reassembling with newer and improved parts by preparing the new part or joint by cleaning up the refurbished surface and welding together.

Worn out parts can also be repaired using MIG welding in various coatings like stainless steel, nickel, aluminium, bronze and a range and grade of hardness for a half the price of purchasing a new part. 

Welding Pipes: Most common welding of pipes with a consistent weld is achieved by automated MIG Pipe Welding.

MIG welding is also used to fortify worn-out railway tracks' surface: It can even strengthen the filling of worn-out railway tracks. It’s not an easy task to join metals of dissimilar types and variants, but you can achieve it over time by opting for the right filler wire.

We hope these applications give you a better understanding of how MIG welding helps in the creation of automobiles, the building of bridges, among many, and a more efficient way to welding.

Suppose you are looking for an efficient weld with welding wires. In that case, several manufacturers specialize in welding wires in the market, for the best MIG wire, trust D&H Secheron as welding wire manufacturers. 

You can reach out to them for all your welding requirements and queries.
