What is 1G 2G 3G 4G 5G 6G welding?

The positions of groove welds are divided into 1G, 2G, 3G, 4G, 5G and 6G, respectively indicating flat welding, horizontal welding, vertical welding, overhead welding, horizontal fixed welding of pipeline and 45 °inclined fixed welding of pipeline.

What is 5G and 6G welding?

There are mainly four types of pipe welding positions- 1G – Horizontal Rolled Position. 2G – Vertical Position. 5G – Horizontal Fixed Position. 6G – Inclined Position.

What is 5G welding position?

5G welding position is a situation where the pipe is in the horizontal or X-axis position, but the pipe is stationary or cannot be rotated. The welder performs the welding while moving it around the pipe. This situation is almost the same as the 1G situation; only the pipe cannot be rotated.

What is 4G position in welding?

4: Overhead

With this key in mind, what 4G mainly covers is Overhead Groove Welding. Meaning, the ability of welding metals to be joined together in an overhead position. Since this is the fourth, that most likely means that it is the hardest to do from the rest of the welding positions.

What does 6G welding mean?

In welding, a 6G position requires one pipe to be positioned at a 45-degree angle to the other. Both are horizontal. This presents a very challenging position for a welder, who uses all his skills and a variety of body positions to accomplish the most difficult weld in the 6G join: the overhead weld. Video of the Day.

Welding Positions - Welding Positions 1G, 2G, 3G, 4G, 5G, 6G, 1F, 2F. 3F, 4F, 5F

What is 1G welding?

1G Position

In the 1G welding position, the pipe is in the horizontal position and can be rotated along the horizontal (X) axis. The welder's position remains stationary. Welding is performed on the top of the pipe. This is the most basic welding position that can be performed.

What is 3G 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 2G welding position?

The 2G welding position is one in which the pipe is vertical and the weld axis is horizontal. The welder welds from the pipe's side in a horizontal welding orientation. Butt welds are placed horizontally in this position.

What is a 3G weld test?

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 a 2G welding test?

A 2G weld test checks your proficiency at producing welds that meet specific criteria for the finished weld and includes: Welding two horizontal beveled plates. Proper setup. Making the weld with or without a backer plate. Passing a final review or other tests.

What is 3F and 4F welding?

With the first digit representing the welding position: 1: welding position by. 2: Horizontal welding position. 3: standing position welding. 4: ceiling welding position.

What is a 6G pipe welding test?

What is a 6G Pipe Welding Test? A 6g pipe welding test is where the pipe is welded with the axis of the pipe at 45%…in a fixed position. When I say fixed position, that means that once welding begins, the pipe cannot be rolled or moved.

What are the types of weld?

There are four main types of welding. MIG – Gas Metal Arc Welding (GMAW), TIG – Gas Tungsten Arc Welding (GTAW), Stick – Shielded Metal Arc Welding (SMAW) and Flux-cored – Flux-cored Arc Welding (FCAW). We dive deeper into each type of welding here.

Which welding position is easiest?

Flat Position (1G or 1F) This type of welding is performed from the upper side of the joint. The face of the weld is approximately horizontal. Flat welding is the preferred term; however, the same position is sometimes called downhand.

What a 2G welding symbol signifies?

Figure: 2F or horizontal fillet weld Figure: 2G or horizontal butt; Figure: 3F or vertical fillet weld Figure: 3G or vertical butt weld. Figure: 4G or overhead butt weld Figure: 4F or overhead fillet weld Figure: 5G or vertical butt, pipe in horizontal axis Figure: 6G or vertical butt, pipe in 45o axis.

How many weld positions are there?

Normally, there are four types of welding positions namely horizontal, flat, vertical, and overhead.

What is 3F welding position?

Description. Learn some tips for welding certification position 3F, or vertical fillet welds. Fillet welds are approximately triangular in cross sectional shape and are made on base pieces whose surfaces or edges are approximately 90 degrees to each other.

What is 4F means in welding?

4F denotes the overhead position of welding fillets while 4G denotes the welding of grooves in the same position.

What are the steps in 6G welding?

What are the 3 main types of welding?

Three of the most common are Arc, MIG (Metal, Inert Gas) or GMAW (Gas, Metal Arc Welding), and TIG (Tungsten Inert Gas) welding. In order to know which process is best for the particular job you're working on, here's what you should know about each of them. Arc welding is the oldest of these three welding processes.

What weld is the strongest?

TIG welding is often considered the strongest weld since it produces extreme heat, and the slow cooling rate results in high tensile strength and ductility. MIG is also an excellent candidate for the strongest type of weld because it can create a strong joint.
