This will give you some insights that may help you determine if welding is a career you should consider. Some of the welding types we will discuss below can be learned by taking welding classes some of which we have enumerated above.
What is welding?
Welding can be defined as a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal.
In other words, the act of joining two materials, also known as substrates, through the use of heat energy focused along the seams is known as welding. Depending on the kinds of substrates being welded together, a wide range of heat energy sources are used. Similar metals should be joined as they will have similar melting points since welding involves fusion by melting.
However, there are situations where a filler with significantly different compositions and consequently, qualities are utilized, such as when welding brittle cast iron. These welds are called heterogeneous. Although welding is frequently an industrial procedure, it can be done anywhere, including outdoors, underwater, and in the open air.
Welding is a risky activity and to prevent burns, electric shock, visual loss, inhalation of toxic gases and fumes, and exposure to strong ultraviolet radiation, safety measures must be taken when welding.

What Are The Types Of Welding
If you a fan of Robert Downey Jr. Then you must have watched the movie Tony Stark: Iron Man (2008). In this movie he welders his first Iron Man suit which he uses to set out and change his life and the world forever.
It’s simple to become daunted by the wealth of knowledge available when you begin learning to weld. Without understanding the many forms of welding, starting your path can be challenging. Some are simpler to pick up than others, and some are rather challenging.
What kind of metal are you going to weld? It significantly impacts everything. We’ve gathered crucial details on nine different types of welding procedures to help clarify the topic.
TIG – Gas Tungsten Arc Welding (GTAW)
TIG welding is one of the most challenging welding processes to learn even though it is quite versatile.
TIG welding is a precise form of welding that produces welds that look good and doesn’t need to be cleaned up because there is no spatter. These characteristics make it a challenging sort of welding that is best left to skilled welders.
TIG welding requires two hands. While the other holds a TIG torch, one hand feeds the rod. The heat and arc produced by this torch are used to join the majority of common metals, such as aluminum, steel, nickel alloys, copper alloys, cobalt, and titanium.
Steel, stainless steel, Chromoly, aluminum, nickel alloys, magnesium, copper, brass, bronze, and even gold can all be joined together using TIG welding. Bike frames, lawnmowers, door knobs, fenders, and other items can all be welded with TIG.
Flux-Cored Arc Welding (FCAW)
Flux-Cored Arc Welding is similar to MIG welding. In reality, MIG welders can frequently also work as FCAW welders. A wire that acts as both the electrode and the filler metal is fed through your wand, just like in MIG welding. Things start to vary at this point. A flux core in the wire used in FCAW generates a gas barrier surrounding the weld. As a result, there is no requirement for an outside gas supply.
FCAW is a high-heat welding style, so it is better suited for thicker, heavier metals. For this reason, it’s frequently employed in heavy machinery repairs. It is a productive procedure with minimal waste. It’s also inexpensive because no outside gas is required. To create a gorgeously finished weld, there will be some leftover slag that will need to be cleaned out.
Stick–Shielded–Metal Arc Welding (SMAW)
Although Stick–Shielded–Metal Arc Welding (SMAW) welding was first developed in the 1930s, it is still being updated and improved upon today. Its popularity has persisted because it is straightforward, simple to learn, and inexpensive to use. However, because it splatters easily, it doesn’t provide the neatest welds. Cleanup is typically required.
The filler metal acts as a replaceable electrode “stick.” The stick’s tip strikes the base metals, sparking an arc that melts the electrode into the filler metal and forms the weld. The stick is covered in flux, which, when heated, emits a gas cloud that shields the metal from oxidation. The gas condenses on the metal and solidifies when it cools, becoming slag.
This procedure can be utilized outside, even in bad conditions like rain and wind, because it doesn’t require gas. It is excellent for fixing equipment because it also cleans, paints, and rusts well. Although it’s not ideal for thin metals, there are numerous types of electrodes that are readily available and can be switched out, making it simple to weld a variety of metals. Stick welding requires a high level of competence and has a steep learning curve.
MIG – Gas Metal Arc Welding (GMAW)
MIG welding is an example of a simpler type of welding for beginners to master. In reality, MIG welding involves two distinct welding processes. First, bare wire is used, and second, flux core.
Thin metal sheets can be joined together using bare wire MIG welding. Because flux core MIG welding doesn’t need a flow meter or a gas source, it can be utilized outside. Homemade enthusiasts and hobby welders who don’t have the money to invest in pricey equipment typically prefer MIG welding.
Plasma Arc Welding
Plasma arc welding is a precision welding method that is frequently utilized in aerospace applications where the metal thickness is less than 0.015 inches. An air seal or engine blade would be two examples of such an application. Ionizing gases inside the arc are used to generate heat in plasma arc welding, which uses a technique that is very similar to TIG welding but with a recessed electrode.
The typical gas mixture is argon + 2 to 5% hydrogen for the shielding gas and argon for the plasma gas. Although it is hotter, helium can be utilized as plasma gas, however, doing so lowers the nozzle’s current rating.
Atomic Hydrogen Welding
Atomic hydrogen welding which used to be called Arc-atom welding is a very intense – heat method of welding. In this kind of welding, two tungsten electrodes are shielded using hydrogen gas. It can be carried out with or without the use of filler metal and can reach temperatures higher than those of an acetylene torch. In recent years, MIG welding has replaced this more traditional type of welding.
Electroslag
This is a sophisticated welding technique where a thin edge of two metal plates is joined vertically. The weld will be put between the edges of the two plates rather than on the outside of a junction. A copper electrode is guided t Through a consumable metal guide tube which will serve as filler metal. When electricity is applied, the arc is formed, and a weld is gradually established at the bottom of the seam and in place of the seam as it moves up. This is a machine-driven, automated procedure.
Electron-Beam Welding
Metals and thermoplastics can both be joined with Laser Beam Welding. The welds are made using a laser, as the name would imply, as a heat source. It can be applied to titanium, aluminum, stainless steel, HSLA steel, and carbon steel. Robotic automation makes it simple to automate, which makes it popular in production, including in the automobile sector.
Electron-Beam Welding
In this kind of welding, two materials are joined together by a fast electron beam’s kinetic energy-generated heat. This is a very advanced type of welding that is done mechanically, usually in a vacuum. There are a lot of words here that a beginner may find difficult, you can check out the definitions of some welding slang to get a better understanding.
What Is The Average Salary Of a Welder?
According to the Bureau of Labor Statistics, the typical welder earns $42,000 a year. According to BLS statistics, 50% of welders in the US make more than that amount, and 50% make less. According to studies by the Fabricators and Manufacturers Association, the average starting pay for entry-level welders is close to $17 per hour.
In the US, statistics show that by 2028, there are expected to be over 488,000 job openings in the field, making welding a vocation with a lot of employment chances that simply keep increasing.
