Welding is an essential component of construction, aviation, automotive, and other industries. Without welding, it is impossible to construct buildings, gates, fences, vehicles, appliances, and other products. There are different types of welding methods and processes. Each welding type has its unique features and is used for various purposes. Let us discuss the types of welding. Read on!
TIG Welding
TIG welding, also known as GTAW welding, is one of the most widely used processes in various projects. TIG welding involves creating a non-consumable electrode made of tungsten. Unlike other welding techniques, you can use TIG welding without the filler metal. So, you can use two metals to weld them together.
However, you can add a filler metal, depending on the project’s requirements. Remember, if you want to use a filler metal, you have to feed it by hand. TIG welding requires a gas tank for constant gas flow to streamline and protect the weld. Therefore, TIG welding produces much better results when performed indoors.
Flux Cored Arc Welding
Flux-cored arc welding is an ideal choice for heavier and thicker metals because it is a high-heat type of welding. Welders and fabricators often use flux-cored arc welding to repair heavy equipment. The process is efficient and does not cause much waste.
In addition, flux-cored arc welding does not require external gas, making it a highly reliable and low-cost process. Although you will see some leftover slag, you can clean it up to make an aesthetically-pleasing finished weld.
MIG Welding
MIG is one of the simplest welding types that allow for high-quality welds. It is an easy technique new welders can use to perform welding of various metals. MIG means “Metal Inert Gas” and is a quick process requiring feeding the filler metal through the wand.
Besides, it expels gas to shield the weld from external elements. So, MIG welding is not an ideal option for outdoor use. However, MIG welding is a versatile and highly efficient process you can use to weld different metal types of varying thicknesses.
Electroslag Welding
Electrostatic welding is an advanced, cutting-edge process used to join thin edges of metal plates in a vertical formation. The welder applies the weld between the edges of the two metal plates instead of the outside joints.
In addition, electrostatic welding involves a consumable metal guide tube to feed a copper electrode wire. It acts as a filler metal and creates the arc after receiving electricity. Remember, the weld begins at the seam’s bottom and moves up slowly. It is an automated welding process performed by a machine.
Gas Welding
Gas welding involves joining metals using fuel gases and oxygen. Gas welding is an ideal choice for welders to cut and weld metals. The process requires the welder to weld edge pieces of metal by heating at the interface. So, this creates coalescence with one or more gas flames, including acetylene and oxygen.
Solid-State Welding
Solid-state welding involves temperatures below the melting point of the materials. Research shows that solid-state welding does not require fillers. Various factors, including temperature, time, and pressure, play a crucial role in jointing the metals without melting them intensely. The most common solid-state welding types include diffusion, cold, forge, hot pressure, roll, explosion, and ultrasonic welding.
