Pipe and Plate Weld Joint Positions

Normally there are six welding positions with certain numbers and letter i.e. 1G, 2G, 3G, 4G, 5G, and 6G/6GR. All the positions are used in various angles and shapes while performing welding. Generally, the ways and ideas of welding are similar in different countries.

6G Welding Positions-

This is one of the hardest types of welding positions for welders to perform. The position is a pre-condition for getting certified. To some extent, this position is similar to 5G/PH/PJ but the pipe stands at 45° to the other one. Other names are 6G Uphill/H-L045 and 6G Downhill/J-L045 Position.

What is the difference between a 6G and 6GR welder?

The welder cuts a slope at a specific angle on the metal, particularly at the edge. Furthermore, in the 6G certification test, the welder has to weld in all positions while the 6GR position is for TKY joints. That’s it on the difference between the 6G and 6GR welder. Both are used to test welders for certification purpose.

What does the R on a 6GR welder mean?

The R means there’s an obstacle to overcome.

Why is 6GR so challenging?

However, the 6GR is considered to be more challenging because of the obstacles a welder needs to overcome to have a smooth weld. If you are pursuing a 6G or 6GR qualification, then we wish you the best of luck. David Huner.

What is 6G weld?

Firstly, the 6G position is the type whereby your tubular weld joint has to be included at an angle of 45 degrees. It’s a difficult test to pass, though not impossible. For a 6G welder to pass this test and obtain certification, the test piece must be welded in its original position.

What do you need to know about 6G welding?

It has a steep learning curve and takes time to master. Therefore, if you want to pass the 6G certification with flying colors, then you need to know the ins and outs of this style of welding.

Which side should I start welding?

By this, I mean the side you know will be more convenient for you to weld the pipe. It will be wrong for you to start welding from the right-hand side when you are right-handed.

Is the 6GR a restriction ring?

Anyway, the 6GR is still more of the 6G position test position, only that it features a restriction ring.

What does the R in 6G welding mean?

This is another 6G weld position that is also challenging. The “R” in the name stands for restricted. In this position, welding is performed in a ring mode. What this means is that a steel plate is placed under the weld site with an inch gap.

What Is Welding Position?

In welding, the welding position is the relative position of the welding gun (hand-held welding torch) and workpiece. The welding gun is held differently for each welding process because different positions affect what type of weld joint can be made. Welding joints are classified according to how the weld pool forms in each particular position. There Are five basic welding positions.

What certification do you need to weld a pipe?

In particular, pipe welders can apply for a 5G and 6G certification . These two are used for the most complex welding positions. Therefore they require more experience. The 6G certification is seen as the gold standard of welding certification. Welders with this certification can weld all-around a stationary pipe.

What does the 3 digit mean in welding?

These numbers refer to the characteristics of the electrode. And the third digit in an electrode’s number designation refers to the welding position it can be used in. For instance, the number “1” means an electrode can be used in all ...

What is horizontal 2G welding?

The horizontal or 2G position is a little bit more complicated than the flat position. In this position, the workpiece is placed parallel to your body when welding. Thus the workpiece remains in front of you when welding.

What is it called when two metals are welded together?

When Two metals joints are welded between their surfaces or their edges or both their surface and edges is called groove weld. They create a V, J, or U-shaped cross-section.

Which position is the most difficult to weld?

The first is the horizontal position, which is difficult and is followed by the flat position and finally, the vertical position. A Lot of practice is needed to perfect this weld position.

What is the most challenging position to welding?

The 6G position is the most challenging because it involves the pipe being fixed at a 45º angle. This requires welding in all positions and incorporates the ‘good’ and ‘bad’ sides that were discussed earlier.

What is the most challenging welding job?

Joining curved pieces of metal is more difficult than welding flat sheets, so by far the most challenging process you’re ever likely to come across is pipe welding, where you will be required ...

What side of a pipe is the most difficult to weld?

For right-handed welders the left-hand side of the pipe is the challenge; for left-handed welders, it’s the right-hand side of the pipe which is the most difficult. Anticipating this obstacle and learning how to overcome it is the best way to ensure super strong, neat welds every time. Always remember that gravity will have an effect on the weld pool, so whichever is your strongest hand, the bottom half of the pipe will probably be more challenging than the top.

How to check for internal weld defects?

X-ray testing is the only really practical method of detecting internal weld defects, which is why it’s used on jobs where the quality of the weld is important for safety reasons. It works in a very similar way to X-rays which we have on the human body to look at broken bones, except on a much grander, more industrial scale. As a result, there are some risks associated with this method, so it should only be carried out by trained professionals. It’s an extremely effective way of checking weld quality which is why it’s used for many pipe welding jobs, but it is the most expensive method by a long shot.

Why is 2G welding flat?

This is pretty much just flat welding because the pipe will be lying on its side (on the curved edge) and can be rotated as you weld. The 2G position is fixed, which means that the pipe cannot be turned as you weld. In this case, the pipe is placed on its base, which makes it much sturdier and more stable to weld.

What is NDT welding?

These three methods are called non-destructive testing (NDT), where the welds must remain intact. However, when you’re practicing or being tested as part of your certification, it may be appropriate to actually break apart your pipe weld by separating it into sections and testing the strength and quality of each one.

What does the letter R mean in welding?

If you come across the letter R in pipe welding codes, this indicates a restricted welding position, which can either be physically or visually.
