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.
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?

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 are the different welding positions?
The above-mentioned welding positions, i.e, flat, horizontal, vertical, and overhead are the most basic types of welding positions used for plate welding. However, these do not completely describe pipe welding positions. As far as pipe welding is concerned, there are four types of piping welding positions. They are: 1 Horizontal Rolled Pipe Weld Position 1G 2 Vertical Position 2G 3 Horizontal Fixed Position 5G, and 4 Inclined Weld Position 6G
What is welding position 2F?
Welding position 2F is for a fillet weld where the welding is performed on the upper side of a horizontal surface and against an approximately vertical surface keeping to welding torch at a 45-degree angle.
What is the most important variable in weld quality?
Welding position is one of the most important variables that determine weld quality. For each pipe weld position, welders need to undergo certification processes. If a welder is qualified to weld in a 1G position, he is not allowed to weld hard positions like 6G position.
What is vertical welding?
In vertical position welding, the weld axis is almost vertical. Both the weld and the plate will lie vertically. For welding vertical surfaces, the molten metal runs downward by gravity and pile up. Welding in an upward or downhill vertical position can resolve this problem.
What is the letter 5 used for?
Letters “5” and “6” are specifically used for piping welding positions in a horizontal fixed position and inclined position respectively. Pipe welding positions will be discussed towards the end of the article.
Why is welding important?
The welding position is very important as it affects the flow of molten filler material. It’s desirable that the welding operator understands the types of welding positions to smoothly accomplish the task. Also, at a certain position of the welder different welding processes are performed. In this article, we will learn about ...
How to get rid of a high crown in welding?
In overhead welding positions, the metal deposited tends to drop or sag on the plate that results in a bead with a high crown. To get rid of this difficulty, the molten puddle should be kept small. When the puddle becomes too large, one can remove the flame momentarily for molten metal to cool.
Why is welding important in 1G position?
Welding positions are important variables to determine weld quality. If welders have the qualification of 1G position, he is not allowed to perform welding in a more difficult condition such as 6G positions.
What angle should the torch be held at when welding?
This position can be used to obtain either a fillet or a groove weld. For a fillet weld, the torch will be held at a 45-degree angle. The weld axis is horizontal. How the positions are executed depends on the type of weld.
What is 1G welding?
The 1G welding position is a position where the pipe is in horizontal positions & the pipe can be rotated against the horizontals axis or the X-axis. The welder does the welding from the top of the pipe. The position of the welder does not change.
What is welding position?
Welding position is a technique that allows the welder to join metal in the position in which they are found or position in which specifics components would be used. Often this can be on the ceiling, in a corner, or on the floor.
What is vertical position welding?
For verticals position welds, both the weld & the plate will be located vertically. One of the major problems when performing these welds is the molten metal flowing down and accumulating. Welding in a vertical position downhill or uphill can prevent this problem.
What angle should a torch be kept at?
To remedy this, torches have to be kept at an angle of 45 degrees. In addition, you use the lower metal of the workpiece to achieve a vertical climbing position.
What are the two aspects of welding?
Welding has two aspects; skills and knowledge . The welder’s skill is assessed by welder performance qualification. This quality is an important demonstration of a welder’s ability to deposit welds. So, things like position, backing, uphill, & downhill, etc.
How many positions are there in welding pipe?
When it comes to welding pipe there are four main positions and again they are typically groove welds. There is also a coding system to identify the positions and joint types.They are as follows:
How to test pipe welders?
Shipyards typically test pipe welders using a box type restricted position . There restricted 6G test does not use a ring or other pipes to block access. Instead it's more realistic for the type of work being done in a shipyard. The pipe is put into the 6G position inside of a welding booth that has a steel grading ceiling. The pipe is placed on the right side of the booth (if you are right handed) 12″ from the right wall. Then 12″ from the ceiling and 12″ from the back wall. If you are looking at the pipe straight on, the right side of the pipe from the 3 to 12 o'clock positions is almost inaccessible. 12 inches of clearance sounds like a lot, but that is 12 inches to the center of the weld joint. So a 6″ pipe has only 9″ of clearance. The restricted area is too tight to put your head in there or too see anything.
How to check if a weld is good?
For most welding certifications given at a welding school the method used is typically destructive testing. This is a low cost and accurate way to find out if the welding student is making good quality welds. The most common is a coupon bend test. This is done by taking the weld test and cutting it up into strips, then bending them to see if the weld holds up. There are many rules concerning the amount the weld coupon can open up or even break. The ideal bent test coupon should show no signs of defects or opening up. There are many other destructive testing methods but the bend test is the most widely used!
What size pipe do you need to weld a fillet?
These two tests usually cover all the positions and most codes allow fillet welds on pipes that are a minimum diameter of 24″.
What are the different types of welding plates?
For welding plate the positions typically come in two different joint types. Fillet welds and groove welds. Most plate welding certifications are performed in groove welds. This is because in most welding codes, grove welds will also qualify you for fillet welds , but fillet welds do not cover groove welds. Fillet welds and groove welds also vary in different positions. The positions are flat, horizontal, vertical, and overhead. There is also a coding system to identify the welding position. The coding system for plate and structural welding is as follows:
What is a welding certification?
Definition: Welding Certifications are technically a hands-on welder qualification test that is conducted by certified welding inspector that will determine if the person or machine can produce a sound quality weld up to the code or welding procedure needed for a Company, job site or a particular industry standard.
What is the largest organization in America that certifies welders?
The largest organization in America that certifies welders is the American Welding Society . The welding certification procedures they have approved have been tested many time to ensure that if followed the welder taking the welding certification follows the rules and has the skills will pass the test.
