What are the four types of welding.

More than 30 different types of welding exist, and they range from simple oxy-fuel to high-tech processes such as laser beam welding. However, only four welding types are used commonly, and they are MIG, TIG, Stick and Flux- Cored arc welding

MIG(Metal Inert Gas)

MIG welding is an arc welding process in which a continuous solid wire electrode is fed through a welding gun and into the weld pool, joining the two base materials together. A shielding gas is also sent through the welding gun and protects the weld pool from contamination. In fact, MIG stands for metal inert gas.

TIG(Tungsten Inert Gas)

TIG can be used to weld copper, titanium, even two dissimilar metals, and is handy for making tricky welds (e.g. s-curves, or welds on round things).. TIG generates heat via an arc of electricity jumping from a (tungsten metal) electrode to the metal surfaces you intend to weld – usually aluminum or steel.

STICK

Stick Welding or Shielded Metal Arc Welding is one of the earliest and most popular welding processes. Its simplicity and versatility contribute to its popularity. It is used primarily to weld iron and steel and is used extensively in the maintenance and repair industries and construction of heavy steel structures.

FLUX

Flux-core welding offers greater penetration, which is good for working with thicker joints. It also allows the welder to travel in all directions and hold the torch in a number of directions. This makes it particularly suited to general repairs, shipbuilding, and other types of manufacturing.

WELDING TIPS

did you know that..

In 1836, Edmund Davy discovered acetylene. But it wasn’t until 1881 that true welding was invented. It started with August De Meritens, who used arc heat to join lead plates together. A Russian student of his, named Nikolai Benardos, then patented a method of electric arc welding with carbon rods.
