Types of Welding Jobs

Atomic Hydrogen Welding (AHW)
Atomic Hydrogen Welding (AHW)

Atomic hydrogen welding (AHW) is an arc welding process that makes use of an arc between two tungsten metal electrodes within an atmosphere composed of hydrogen. The process was invented by Irving Langmuir in his studies about experiments about atomic hydrogen.

Carbon Arc Welding (CAW)
Carbon Arc Welding (CAW)

In the arc welding, the arc is used to create intense heat and this heat is used to join the metals together. the arc is brought in between two metal pieces and due to the heat generated, the metals melt and when it cools a strong welded joint is formed.

Electroslag Welding (ESW)
Electroslag Welding (ESW)

Electroslag welding (ESW) is a highly productive, single pass welding process for thick (greater than 25 mm up to about 300 mm) materials in a vertical or close to vertical position. (ESW) is similar to electrogas welding, but the main difference is the arc starts in a different location.

FCAW (Flux-Cored Arc Welding):
FCAW (Flux-Cored Arc Welding):

Flux cored arc welding is a process similar to MIG welding. Both processes using continues wire feeds, and similar equipment. The power supply for a FCAW, and a MIG welder, are the same machine.

Flux Cored Arc Welding (FCAW)
Flux Cored Arc Welding (FCAW)

Flux cored arc welding just like MIG welding requires three main ingredients, electricity, filler metal, and a form of shielding from the air. Just like MIG welding, flux core welding works by feeding an electrode continuously to the joint.

Gas Metal Arc Welding (GMAW/MIG)
Gas Metal Arc Welding (GMAW/MIG)

Gas Metal Arc Welding (GMAW) GMA – commonly referred to as Metal Inert Gas (MIG) – welding embraces a group of arc welding processes in which a continuous electrode (the wire) is fed by powered feed rolls (wire feeder) into the weld pool.

Gas Tungsten Arc Gas Welding (GTAW/TIG)
Gas Tungsten Arc Gas Welding (GTAW/TIG)

Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld.

MIG Welding
MIG Welding

MIG welding is the best choice for spot welding and tack welds. When welding soft metals like aluminum there is special equipment that is needed to be added to the MIG welder. Harder metals like stainless steel work fine on any MIG welding machine as long as you pay attention to keeping the cord straight.

Shielded Metal Arc Welding (SMAW)
Shielded Metal Arc Welding (SMAW)

Shielded Metal Arc Welding, otherwise known as manual metal arc welding or flux shielded arc welding, is a process that uses a flux-coated electrode to form the weld. As electricity passes through the electrode, the flux forms a gas, which shields the electric arc in the space between the electrode and the metal being welded, preventing contamination from atmospheric gasses in the weld.

Stick Welding
Stick Welding

Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.

Submerged Arc Welding (SAW)
Submerged Arc Welding (SAW)

Submerged arc welding (SAW) is a common arc welding process. The first patent on the submerged-arc welding (SAW) process was taken out in 1935 and covered an electric arc beneath a bed of granulated flux.

TIG Welding
TIG Welding

The major difference between Mig and Tig welding is that one process uses a continuously feeding wire (MIG) and the other you use long welding rods and slowly feed them into the weld puddle (TIG). MIG and TIG welding both use an electric arc to make the weld. MIG welding is a very simple and easy process to learn compared to learning how to TIG weld.
