5G welding position is the welding of the pipe in horizontal position that cannot move and is fixed. It is also named as PF in ISO/EN standards. In 5 G welding is done vertically either upwards or downwards. 6 G position is used to weld a pipe joint inclined at an angle of 45 degree. Thus, the information on types of welding positions like 1G, 2G, 3G, 4G, 5G, and 6G/6GR is beneficial for students, welders, educators, and other professionals. Welding positions play the main role in the certification process for welders. They may be tested for positions starting from 1G to 6G both for the fillet and groove welds. The positions you encounter when Pipe welding are many and usually the position will be fixed, however it’s not uncommon to be in a flat position. Horizontal Pipe Rolled: Step 1: You will align Align the joint, tack weld it, or you can hold it with bridge clamps (made of steel) and your pipe should be placed on rollers.
Welding certifications are procedures that a welder must follow to produce a sound weld according to the guidelines that are specified. The certification is a hands-on welding test, supervised by an individual that is trained and approved by the certifying organization. These tests or certifications only qualify the welder for a single process and position. There is not a single welding certification that certifies a welder for all processes, metals, or positions.
There are several good welding schools and vocational schools to learn the trade and receive a welder certification. At most vocational schools, the student will leave with an associate’s degree after completing the welding program. For those students wanting more in-depth education and greater employment opportunities, a welding engineering bachelor’s program is available.Welding Certification Tests
Most welding certification tests are based on codes written by one of three organizations, depending on the type of work involved and what organization is overseeing the welding procedures. In the United States the three biggest organizations are the:
*AWS – American Welding Society
*ASME – American Society of Mechanical Engineers
*API- American Petroleum Institute
Even though the above organizations are the largest, there are many others like:
*ABS – American Bureau of Shipping
*MIL – STD – Military Standards
*The Canadian Welding Bureau
*D.O.T. – Department of Transportation
*State and Local Welding Certifications Codes
Knowing which code to be a certified welder in is essential, as welders are only certified to weld within the code parameters of the test they have taken.
Most of these codes certify the welder for a specified length or period of time. In most cases, the welder must have a logbook signed to show that they have welded with the process and in that position at a job site every six months. The reason behind this is that most welders lose their skills in as little as two weeks without consistent practice or use. Even after a weekend of not welding, most people find their appearance of a quality weld goes downhill. It takes consistent practice to keep your eye/hand coordination at its peak level at all times. Simcheck a300 liveries. Because of this, it’s important to focus on the certification for the type of welding you most frequently do.
One of the most common welding codes is AWS D1.1, which covers structural steel. Passing the test on a 3/8″ thick plate, with backing in the vertical position, you would then be qualified to weld in the flat, horizontal and, vertical positions.Welding Certification Processes
The most four common types of welding processes used for certifying welders are:
*SMAW / Shielded Metal Arc Welding – Typically referred to as Stick Welding.
*GMAW / Gas Metal Arc Welding – Commonly called MIG Welding.
*FCAW / Flux Cored Arc Welding – Just another type of electrode for a MIG welder.
*GTAW / Gas Tungsten Arc Welding – Most people know it as TIG Welding.
There are many other welding processes that a welder or even a welding machine can get certified. Some examples include:
*Resistance Welding
*Brazing
*Soldering
*Plasma Welding
*Laser Welding
*Stud Welding
*Submerged Arc WeldingWelder Qualification Testing
Welder qualification testing consists of questions on the types of welding symbols, safety, welding processes and positions, types of welds, material handling, and more. The hands-on qualification test is conducted by a certified welding inspector who will provide a visual inspection and observe the welder’s skill level. Depending on the type of welding, it can either be a nondestructive test (NDT) or a destructive test.Welding Certification Positions
Welding certifications come in many different positions depending on the type of structure that will be welded. In most cases, it is broken down between structural and pipe welding. Structural positions are for welding work plate and are the easiest to pass. Pipe positions are good for welding plate and pipe depending on what the structural welding code allows. Pipe certifications are much harder because it is an ever-changing position and never a simple straight line.Structural positions have a coding system that identifies the position and joint type. The coding system is as follows:
*1 stands for the flat position
*2 stands for the horizontal position
*3 stands for the vertical position
*4 stands for the overhead position
*F stands for a filler weld joint
*G stands for a groove weld joint
The way this system works is the position is first stated with a number, then right next to it the letter specifies the type of weld joint used. Here are some examples:
*1F is a flat weld done using a fillet joint.
*2F is a horizontal weld done using a fillet joint.
*3F is a vertical weld done using a fillet joint.
*4F is an overhead weld done using a fillet joint.
*1G is a flat weld done using a groove joint.
*2G is a horizontal weld done using a groove joint.
*3G is a vertical weld done using a groove joint.
*4G is a vertical weld done using a groove joint.
When it comes to structural certifications, in particular, groove welds will also qualify the welder for fillet welds. However, fillet welds do not qualify the welder for groove welds. Most codes allow a welder to take a combination of the 3 and 4G certification positions, which typically qualifies the welder for all position structural welding plus pipe that is a minimum of 24 inches in diameter.Pipe welding certifications also have a coding system to identify the position and joint type. They are very similar to structural welding but are more difficult to pass. The positions have the following designations:
*1 stands for a pipe that is in the horizontal position and the welder welds in the flat position while rolling the pipe.
*2 stands for a pipe in the vertical fixes position and the welder welds in the horizontal position.
*5 stands for a pipe in the horizontal fixed position and the welder welds in the overhead, vertical and flat positions.
*6 stands for a pipe in a fixed 45 degree position and the welder welds in the overhead, vertical, horizontal and flat positions.
*F stands for fillet weld.
*G stands for groove weld.
*R stands for restricted.
Pipe welding test positions have the same coding system as structural positions with one main exception. That is the “R” or restricted position. The restrictions used for pipe welders are designed to make the test as difficult as possible and, at the same time provide the same types of obstacles that the welder will encounter in the field. Just like structural welding positions you simply identify the position with the number, then the joint type with the letter and finally if it is restricted there will be an R., For example, a 6GR test would be a pipe in the fixed 45 degree position with a groove joint that is restricted.
Combination pipe welding certifications are not very common these days, but there is one combination that is still used. The 2G and 5G combination welding certification is also considered a 6G certification. For most pipe welders, they will take the 6G welding certification, and that certifies the welder for all position pipe welding plus all position structural welding. For most welders, the metal that they certify in is carbon steel or A36 steel. For other metals like stainless steel and aluminum, it is more of a job-specific certification that in most cases their employer pays for.

The welding position refers to the position of the welding operator towards the workpiece to be welded. Because of gravity, the welding position affects the flow of molten filler metal. It’s important to understand the types of welding positions as different welding processes require to be performed at a certain position of the welder.
There are four main types of welding positions, which we will cover below.
Table of Contents
*1 4 Basic Welding Positions4 Basic Welding PositionsFlat Position (1G and 1F)
The easiest type to perform is the flat position, which is also sometimes called the downhand position. It involves welding on the top side of the joint. In this position, the molten metal is drawn downward into the joint. The result is a faster and easier weld.
In 1G and 1F, the number 1 refers to the flat position, while the letter G stands for a groove weld and letter F stands for a fillet weld.Horizontal Position (2G and 2F)
This is an out of position welding position. It’s a more difficult position compared to the flat position and it requires more skill from the welding operator to do them well.
2G is a groove weld position that involves placing the weld axis in a horizontal plane or approximately horizontal. As for the face of the weld, it should lie in an approximately vertical plane.Pipe Weld Position
2F is a fillet weld position, in which the welding is done on the upper side of the surfaces that is approximately horizontal that lies against a surface that is approximately vertical. In this position, the torch is usually held at a 45-degree angle.Vertical Position (3F and 3G)
In this position, both the plate and the weld lie vertically or almost vertically. The 3F and 3G refer to vertical fillet and vertical groove positions.
When welding vertically, the force of gravity pushes the molten metal downward and so it has the tendency to pile up. To counteract this, you can use either an upward or downhill vertical position.
To control this in the upward vertical position, point the flame upward, holding it at a 45-degree angle to the plate. This way, the welder will use the metal from the lower parts of the workpiece to weld against the force of gravity.3g Welding Position Qualification
In the downhill position, the metal from the upper parts and the electric arc’s kinetic force are used.
Overhead PositionMig Welding 4g Position
In this position, welding is carried from the underside of the joint. It’s the most complicated and difficult position to work in. The 4G and 4F positions stand for groove and fillet welds respectively.
In the overhead position, the metal deposited to the joint tends to sag on the plate, resulting in a bead with a higher crown. To prevent this, keep the molten puddle small. If the weld puddle becomes too large, remove the flame for a moment in order to allow the molten metal to cool.5g Welding Position
The positions flat, horizontal, vertical and overhead are the basic types of welding positions. However, they do not adequately describe pipe welding positions. Pipe welding can be done under many different requirements. These positions we’ll cover in a separate article.4g Welding Position SmawRelated Posts:
