7 Different Types of Welding -Which one is the Best?

Joining two parts of metal has been one of the finest pieces of art in the world. Since the dark age, the blacksmiths used to use forge welding methods to do their day to day work and make equipment to enrich the empire. And today there are different types of welding and none of the methods are matching the ancient ones.

After the 19th century, thighs changed a bit for the better good and people started to join the metal using the actual spot weld welding techniques. Arc welding and oxy-fuel welding was one of the very first welding tricks that gave success to join iron and steel by heating the filler metal rather than hammering. 

What is Welding?

Welding is a metal fabrication process where two metals are fused with extreme heat and pressure to form a join and make an industrial reusable structure. Mostly a solid wire or a flux-cored wire is used to breed the weld which is often made of mild steel or carbon steel and a cover prevented oxidation to aid in electrical conduction. 

Types of Welding

There are seven types of welding. But most welder masters one or two and be very good at it. The most common process is:

  • MIG Welding – Easiest to learn
  • TIG Welding – Most powerful
  • Stick Welding
  • Laser Beam Welding
  • Electron Beam Welding
  • Fluxed-cored welding
  • Atomic Hydrogen Welding

While there is welding attached to all of them but they are somewhat different from each other.

MIG Welding

MIG stands for Metal Inert Gas. It is the kind of welding process solid wire electrode run through a welding gun and into a weld pool and making sure of the join of two metals together. A MIG welder sends a shielding gas with the wire and through the welding gun to protect the pool from contamination and make a perfect weld bead with shielded metal arc welding.

TIG Welding

TIG Welding also is known as the Tungsten Inert Gas welding or Gas Tungsten Arc Welding (GWAT). It is an Arc welding process that uses a non-consumable tungsten electrode to join and fabricate the metal piece to one strong bond. TIG welding is referred to be the strongest and the most powerful welding process of gas metal arc welding because of its ability to join aluminum and magnesium. TIG welding became a popular process in the 1940s and maintained its reputation to date. 

Stick Welding

Stick welding, also known as Sheild Metal Arc Welding (SMAW) is a welding method that uses electricity to melt a filler electrode or rod and fill the joint to join two metal and fabricate together at the same time. Stick Welding is used as a slang for SMWA as the electrode is used for this process is mostly stick liked. Stick welding uses both DC and AC and the process is most likely as the TIG welding.

Laser Beam Welding

Laser Beam Welding (LBW) is a welding method that uses a laser to join the pieces of metal and the thermoplastics. The laser beam provides a heave and focused heat source that allows a deep and narrow weld of base metal alongside a high welding rate. This spot weld technique is widely used in the automotive industry to provide welding at a low cost, such as door, roof, and filter assemblies. 

Laser-Beam-Welding

Electron Beam Welding

Electron Beam Welding (EBM) is an expensive welding process that utilizes the heat generated by a beam of high electron energy. The process emphasizes the electron to hit the material with their kinetic energy and converts the electrode wire into thermal energy to heat the metal so that the edge of the cast iron or alloy steel are fused to make an indestructible weld bead and a flash weld.

Fluxed-cored welding

Flux-cored Arc Welding (FCWA or FCA) is a nonautomated or semi-automatic welding process that is similar to Metal Active Gas (MAG) welding process which uses a wire feed, a voltage power supply, and a regular welding machine. Fluxed cored welding is more popular among the welders nowadays because of its quality welds, consistency, and high welding speed form MAG and friction welding.

Atomic Hydrogen Welding

Atomic Hydrogen Welding (AHW) is an Arc welding process that uses an electronic arc between two tungsten electrodes at a hydrogen contained chamber. It contains two tungsten electrodes so, it’s faster and more expensive than the regular flux-cored welding but it produces very less distortion.

What is Fusion Welding?

Fusion is the common term of welding that refers to heating two parts of metal the extreme level of temperature to melt them and join them with each other with collaboration. With the very high-temperature level, a phase transition takes place in the process and a heat-affected zone is centralized between two metals which makes both of the metals get to each other. 

What is the strongest type of weld?

There are several types of welding in the market and it is hard to pick one as stronger than the other as all of them are subjective and better than the other in some aspects. While MIG welding is easy to learn and use in every aspect, if we are talking about sear power, you would have to go with TIG. TIG is the most aesthetically pleasing and the most diversified welding technique for decades. It is also suitable for almost every condition. You can even go for plastic welding, high-frequency oxyacetylene welding, or friction stir welding if you are into it.

Which type of welding is the best?

Everyone’s preference is different, every need is different and everyone has different kind of skills set. So, there is no best type of welding. But for the beginners, the most common type of welding that expert welders recommend is MIG welding as its easy to learn and easier to execute. You can start by MIG welding and gain experience to go for the TIG welding with stainless steel or even the Atomic Hydrogen welding if you can gain the expatriates on that. 

There are several welding programs you might find useful if you are would like to improve your skills of projection welding or groove welds for welding equipment and welding stick and thicker metals.

Final Words

Along with these seven welding types, there are several other processes of welding such as resistance welding, stud welding, electric arc, orbital welding, wave soldering, seam welding, plasma arc welding, spot weld, Acetylene torch brazing, friction welding hot-dip brazing, electro slag welding, ultrasonic and many more. But all these are some sub-sector of the seven techniques that are discussed here and most of them are some version of Arc Welding.
