What are the components of MIG welding?

Basic Components of MIG Welding Machine

• Power supply. The power supply is the prime area of any MIG machine as it controls many variables.
• Torch. The torch is also known as the MIG welding gun.
• MIG welding wire. The welding wire is very critical in the process of MIG welding.
• Earth clamp or ground clamp.

What causes air bubbles in MIG welding?

Porosity in welding happens when a contaminant or gas is absorbed into the weld puddle. Basically porosity in welding is a weak, bubble-filled weld that does not meet code and more importantly can in some cases, cause part of a project to become weak and collapse.

What gases do MIG welding use?

The four most common shielding gases used in MIG welding are Argon, Helium, Carbon Dioxide and Oxygen.

Is Tig as strong as MiG?

TIG welding produces cleaner and more precise welds than MIG welding or other Arc welding methods, making it the strongest. That said, different welding jobs may require different methods, while TIG is generally stronger and higher in quality, you should use MIG or another method if the job calls for it.

What is MiG arc brazing?

MIG brazing, or arc brazing, was introduced in the 1990s. It greatly resembles MIG/MAG welding . The greatest difference is in the filler material wires and the melting of basic material , as the basic material does not melt in MIG brazing.

What is torch welder?

The torch is the tool that the welder holds and manipulates to make the weld. It has a connection and valve for the fuel gas and a connection and valve for the oxygen, a handle for the welder to grasp, and a mixing chamber (set at an angle) where the fuel gas and oxygen mix, with a tip where the flame forms.

What is a welding gun?

Welding Gun. a portable device for semiautomatic welding of parts of various articles. Guns are used where welding with stationary equipment would be difficult or impossible. They are used in the manufacture of automobiles, railroad cars, farm machinery, and similar equipment. They are also used for work performed under unusually complex operating…
