Can you imagine a world without welding? How would people build so many things, such as buildings, gates, fences, various vehicles, etc., without this form of metalwork?
The main job of welding is to create a firm connection between two elements to join them. Whether it is skyscrapers, cars, ships, or airplanes, welding is necessary for all industries.
However, there are many welding techniques available. Here, you will get an overview most popular welding techniques Mig & the differences mig & other techniques.

MIG Welding Vs TIG Welding
Specifications |

Electrode Type |
Consumable electrode |
Non-consumable electrode |
Filler Length |
Longer filler |
Shorter filler |
Weld Cleaning |
Highly necessary |
Not necessary |
Disposition Rate |
Higher disposition rate |
Lower disposition rate |
Gas Used |
Helium, oxygen, and nitrogen |
Argon |
Ideal Usage |
Homogenous welding |
Autogenous mode welding |
Overview
- Welders use consumable electrodes in MIG welding techniques to fill the root gap. They become a part of the welded joint.
But TIG Welding has non-consumable electrodes to prevent melting or being consumed during welding.
- It is necessary to clean the weld properly in MIG welding to boost the welded joint’s life expectancy and corrosion resistance where for tig it is not mandatory
- The deposition rate of MIG welding is higher than TIG Welding due to an intermittent wire feed. It positively impacts on productivity and efficiency of the welder
- MIG welding is ideal for homogenous welding because this versatile welding technique is used for various materials to achieve a consistent and precise weld.
In contrast, TIG welding is a better choice in autogenous mode welding as it provides greater control over the welding process.
Which One Is Best For Beginners?
Both welding techniques are not too hard to master. Mig welding is easier than tig welding when it comes to learning. Weldingintro.com says a newbie welder must try the mig welding technique first. It is preferable to TIG Welding for beginners due to its ease of use and forgiving nature.
But if you want to do welding projects, especially on art or sculpture, and pipes, a TIG welding technique is a good choice.

Outdoor applications |
Overview
- MIG welding uses consumable electrodes, whereas stick welding uses heavy-coated electrodes. The main advantage of heavy-coated electrodes is providing better control with less spatter.
- Welders use helium, oxygen, and nitrogen shielding gas in MIG welding. But they don’t need any external shield gas in stick welding. However, the decomposition of the electrode coating forms a special gas to protect the weld from atmospheric contamination.
- MIG welding is a relatively low heat input welding process. So, thinner metals are better for this welding technique. On the contrary, stick welding is a high-heat input welding process that can generate more heat than MIG.
- MIG welding is better for internal applications, whereas stick welding is perfect for external applications.
Which One Is Best For Beginners?
Compared to stick welding, MIG welding is easier to learn and requires less skill than stick welding.
However, before choosing a particular welding technique, you need to consider the welds’ materials, thickness, and position. You shouldn’t overlook the required welding speed and the available equipment and supplies also.
MIG Welding Vs. Flux Core Welding
Specifications |
MIG Welding |
Flux Core Welding |
Electrode Type |
Consumable electrodes |
A hollow or tubular electrode |
Shielding Gas |
Helium, oxygen, and nitrogen |
Carbon dioxide |
Welding Wire Type |
Solid wires |
Tubular and flex-cored wires |
Welding Position |
All positions |
Flat and horizontal positions |

Ideal usage |
Thinner and non-ferrous metals |
Dirty or rusty and thicker materials |
Overview
- MIG welding uses consumable electrodes, whereas flux core welding uses hollow or tubular electrodes. The main advantage of this type of electrode is improving arc action and weld metal properties. You will get quality welds.
- Welders use solid wires in MIG welding to avoid oxidation and improve the life of the welding contact tip.
In contrast, Tubular and flux-cored wires are used in flux-core welding for improved fusion with the base metal due to its higher current density. It also ensures a better, smoother, uniform bead appearance with minimal spattering.
- The MIG welding technique is a perfect choice for non-ferrous metals as it can produce high-quality welds with faster speed and low distortion levels.
But, flux core welding is better for dirty or rusty and thicker materials. It contains a fluxing agent to protect the weld pool from contaminants.
Which One Is Best For Beginners?
If you are only handling thinner-based metals, MIG welding is the best choice due to its ease of use and versatility.
But when you are welding both thicker-based items, use flux core welding.
It is especially helpful for outdoor and windy conditions because of its self-shielding capabilities.
Conclusion
A welder can use a wide range of welding techniques. Before selecting a particular one, consider specific materials, the thickness of the material, and weld quality.
MIG welding is overall a better welding option for novice welders if they are only handling thinner-based materials.
It is highly versatile to fit various materials such as stainless steel, aluminum, mild steel, etc.
But if you want to work on thicker-based metals, you may need to use TIG, flux core, or stick welding based on the welding requirements and your project type.
