What is 3G MIG welding?

The 3G welding certification qualifies a welder to weld flat, horizontal, and vertical or 1G, 2G, and 3G positions, also includes the 1F, 2F, and 3F positions without having to take the 1G and 2G certification. This one test qualifies you for three positions. These are the positions most commonly used in welding shops.

What is 3G means in welding?

Welding in a 3G position means moving the torch vertically, up and down across a surface. This is in contrast with 1G (flat surface welding), 2G (horizontal welding), and 4G (overhead ceiling welding).

What is a 5G weld?

In the 5G welding position, the pipe is in the horizontal position. Unlike the 1G position, the pipe is in a fixed position and it cannot be rotated. The welder moves around the pipe in the vertical direction to perform the welding.

How long does a MIG certification last?

Every six months after you receive this certification you must submit a maintenance form to AWS verifying that you’re still performing the same welding you were initially tested on.

  • What does MiG in MIG welding stand for?

    MIG – ‘MIG’ stands for ‘Metal Inert Gas’ welding, but you might also see it referred to as ‘GMAW’ (‘Gas Metal Arc Welding’), or ‘MAG’ (‘Metal Active Gas’ welding). This is one of the most common welding techniques – and one of the easiest to learn – so it’s great for both beginners and large scale production.

    What is the difference between MIG MAG and GMAW welding?

    – What base metals are being used? – Is a MIG or a MAG welding setup being used? – How does the cost of the shielding gas affect the cost of the final product? – What kind of joint is being welded? – How clean are the materials being used?

    What can be welded with a MIG welder?

    Working with a Spool Gun. A spool gun reduces the wire’s travel distance to the weld pool.

  • Choosing the MIG Wire. To weld metal,you’ll need an aluminum wire,usually the alloys 4043,5356,and 5554.
  • Cleaning the Work Metal. The metal needs to be clean when you’re welding aluminum.
  • Controlling the Speed.
  • Getting the Shielding Gas.
