What is the 5G pipe welding position?
During 5G, welders go through three welding stages starting from flat position, then horizontal position and ending with the overhead position. Different names of 5G welding position by the following bodies: 6G Welding Positions- This is one of the hardest types of welding positions for welders to perform.

How do you weld a 4G stick?
How do I pass a 4G welding test?
- clean mill scale with a sander or grinder about 1/2" away from the bevel.
- take care to have an even and full 1/4" gap.
- set amperage to a setting that allows you to hold a very tight arc without sticking the rod.
- hold a tight arc and use a very slight drag angle.
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.
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 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 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 is flat welding?
In the flat position, the joint or workpiece to be welded is placed under the welding torch. In this regard, the molten metal flows downward into the joint. The result is an easy to accomplish weld. This weld position can be used to perform groove, fillet, and butt welds.
What is welding position?
A welding position means the posture you need to assume towards the workpiece you are welding. In some cases, you will need to weld the workpiece in the position you find it and not adjust it in any way.
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.
What is the slope of a 6G welding?
In the 6G welding position, the pipe slopes at approximately 45° from the horizontal (X) axis or 45° from the vertical (Y) axis. The pipe is in a fixed position, so the welder must move around the pipe to perform the welding. This is an advanced welding position that requires a great deal of experience and technical expertise.
What is 1G welding?
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 welding mastery?
A welder's mastery over each welding position acts as a certification that qualifies him or her to perform more types of welding work. In other words, mastery over each position levels up a welder's qualifications. For instance, if a welder only a 1G position qualification, he cannot conduct welding in more advanced positions such as 2G, 5G, or 6G. If a welder has attained a 6G position qualification, he or she is permitted to carry out welding in the 1G, 2G, and 5G positions. These standards must be maintained in order to preserve the safety of the work environment.
What is the 5G welding position?
In the 5G position, the pipe is not turned or rotated.
What is 6G welding?
The 6G welding test, also known as the Arkansas bellhole test, is a means to identify the skills or lack of them in a welder. It's stringent test, because the welder must use a variety of techniques, such as flat, vertical and horizontal welding to achieve a successful 6G weld.6 G position is used to weld a pipe joint inclined at an angle ...
What is a tig used for?
In case of TIG it is limited to appearance or limited strength , in some cases it is used for stress relieving of long MIG welding joints in Auto line.

What is the advantage of tig welding?
Added advantage of TIG is it can be use for different process too. 1, Welding can be done without adding filler metal . 2, It can be use to preheat the work piece for stress reliving or other process where preheating of job is require. 3, It can be use in tool room for preheating before machining, in certain cases.
How thick can a TIG be?
You can use for higher thickness upto 40 mm , it is very fast process with higher accuracy. In case of TIG it is limited to appearance or limited strength , in some cases it is used for stress relieving of long MIG welding joints in Auto line. One can use it for limited thicknesses may be upto 6mm maximum.
What type of transfer is used in MIG welding?
You can use short ckt transfer, globular transfer, spray transfer and pulse transfer. You can use for higher thickness upto 40 mm , it is very fast process with higher accuracy.
How many o'clocks do you rotate before welding?
The welder must rotate himself/herself to complete the joint. Generally before welding, the positions of 3,6,9,12 o'clock are marked and the welding is started from 6 to 12 and then from 6 to 6 clockwise as per the welder’s suitability. It is not very simple. Experience and expertise are both needed for a flawless weld.
