Industrial welding encompasses a variety of techniques used to join metal parts, and each method has its advantages and disadvantages. MIG/MAG welding is one of the most commonly used Gas Metal Arc Welding (GMAW) methods.
This welding technique uses a heat source to melt and join metals, and a shielding gas to prevent oxidation and contamination. If you are looking for an industrial welding expert to meet the demands of your industrial metal welding projects, HARtech is here to help.
Join us as we explain how MIG/MAG welding is used and what its advantages and disadvantages are for different industries.
The MIG/MAG welding process
The MIG/MAG (Metal Inert Gas/Metal Active Gas) welding process is widely used in industry to join metal parts using an electric arc. This welding technique is characterized by the use of a shielding gas, which protects the weld from the ambient air and prevents oxidation. MIG/MAG welding is quick and versatile, as it can be used on different types of metals of various thicknesses.
The MIG/MAG welding process demands technical expertise for high-quality results. At HARtech, we offer superior MIG/MAG welding services thanks to our team of professional welder-assemblers and state-of-the-art equipment. We can help you choose the right shielding gas, prepare materials, adjust welding parameters, and make accurate and durable welds.

What is the difference between TIG and MIG/MAG welding?
TIG welding and MIG/MAG welding are two different welding processes, each with advantages and disadvantages. Here are the main differences between these two welding techniques:
- TIG welding uses a non-consumable tungsten electrode to create the electric arc, while MIG/MAG welding uses a consumable wire electrode that is fed continuously.
- The TIG method uses an inert gas (usually argon) to shield the welding area from the ambient air, while MIG/MAG welding uses either an inert or active gas to shield the welding area and prevent contamination.
- The TIG welding process is often used for high quality welds, especially for thin materials, while MIG/MAG welding is often used for high-speed production welds on thicker materials.
- TIG welding offers greater heat and melting control, resulting in more accurate welds, while MIG/MAG welding is easier for novice welders or large welds.
- TIG welding is often used for welds that need to look good, while MIG/MAG welding is often used for structural welds or industrial settings where aesthetic value is less important.
At HARtech, we have extensive experience in both TIG and MIG/MAG welding processes. We can help you choose the best welding process for your project according to your specific needs and desired quality.
Advantages of MIG/MAG welding
MIG/MAG welding offers many advantages which make it a popular choice for many projects. Let’s examine at a few of the reasons for its widespread use.
MIG/MAG welding can be used to weld quickly. The wire electrode unwinds automatically, and fusion takes place instantly thanks to the electric arc. It is possible to weld large parts in a single pass, which saves time.
Because MIG/MAG welding can be done so quickly, it increases workshop productivity. When you don’t need to wait long between welding operations, you can produce quality materials in record time.
MIG/MAG welding produces quality welds with good penetration and minimal part deformation. It can be used to obtain a regular and aesthetic weld bead.
MIG/MAG welding is very versatile and can be used to weld different metals, including steel, aluminum, copper, brass and even stainless steel. Simply choose the right shielding gas and wire electrode for each material.
MIG/MAG welding produces minimal fumes and spatter, which means fewer rejects and better working conditions in your industrial facility. Fewer rejects also means limited material losses and reduced production costs.
The disadvantages of MIG/MAG welding
The advantages of MIG/MAG welding are many. Let’s take a look at its potential disadvantages.
Sensitivity to external conditions
The MIG/MAG process is sensitive to external conditions such as air currents, dust and particles, each of which can affect weld quality. It is important to work in a clean and stable environment to produce high quality welds.
High upfront cost
The initial cost of purchasing MIG/MAG welding equipment can be high, especially if you opt for high quality equipment or advanced technology. However, in the long run, MIG/MAG welding can be more cost-effective than other welding processes because it guarantees speed and high productivity.
MIG/MAG welding can be difficult to use in vertical and overhead positions. This can put limits on a welder’s ability to make certain types of welds.
Surface cleaning and preparation
Before beginning a MIG/MAG welding process, the welding surface must be carefully prepared. Surfaces must be properly cleaned to avoid contamination and ensure proper adhesion.
The common applications of MIG MAG welding
MIG/MAG welding is used in a variety of industrial and manufacturing sectors including automotive, aerospace, shipbuilding, and structural steel fabrication.
- In the automotive industry: MIG/MAG welding is widely used for the assembly of car and truck bodies, when it is necessary to quickly and accurately weld thin sheets and complex structures made of steel, aluminum and light alloys. It is also used to manufacture components such as seat frames and suspensions.
- In the aerospace industry: this method is ideal for manufacturing aluminum and titanium alloy parts, such as air ducts, intake manifolds and engine mounts.
- In shipbuilding: MIG/MAG welding is used to assemble hulls and superstructures made of steel, aluminum and copper-nickel alloys. Welding speed, productivity and weld quality are some of the advantages it offers in this context.
- In structural steel fabrication: MIG/MAG welding is used when assembling steel beams, frames and complex steel structures. It is a fast and efficient technique for making high quality welds on large parts.
