Welds with a 1 are flat position, 2 is horizontal, 3 is vertical and 4 is overhead. F stands for fillet weld, while G is a groove weld.
5G and 6G Welding Positions
In the 5G welding position, the pipe is in the horizontal position, whereas in 6G position, the pipe slopes at approximately 45° from the horizontal (X) axis or 45° from the vertical (Y) axis. Unlike the 1G and 2G position, the pipe is in a fixed position and not rotating.
A) For Groove Welding :
2G – horizontal welding position. 3G – vertical welding position. 4G – welding position overhead or overhead) 5G – uphill and downhill vertical welding position.
The 1G welding position, also known as the flat position, is the simplest and most comfortable welding position for most welders. In this position, the welder lays the workpiece horizontally, enabling them to deposit the weld bead using gravity.
The 6G pipe weld is one of the most difficult weld certification tests to pass because the pipe is at a 45-degree angle and immovable. Welders performing the 6G certification test must weld in all positions including horizontal, vertical and overhead, and may have to weld both right-handed and left-handed.
8G, a candidate shall meet one of the following: One year's welding experience, subsequent to or during an apprenticeship to an acceptable trade, including 40 hours' training in the welding of plate and pipe using the gas metal-arc welding process.
The positions of groove welds are classified as 1G, 2G, 3G, 4G, 5G, and 6G, respectively representing flat welding, horizontal welding, vertical welding, overhead welding, horizontal fixed welding of pipelines, and 45° inclined fixed welding of pipelines.
6G Coded Welding refers to welding pipe in the 6g position. The number “6” represents the position of the pipes, while the letter “G” stands for the type of weld, in this case, a groove weld. A groove weld is a joint in two metal pipes where the space between them is filled with the welding material.
The Certified Welding Supervisor (CWS) certification is the highest designation available to welding professionals. CWS certifications are recommended for those who have reached managerial positions in the field. The certification is ideal for welding leaders with experience in quality assurance and problem-solving.
2G testing refers to a certification test that proves a welder can lay a horizontal weld in a groove joint between two metals. If a welder passes the weld test, they are also certified to perform groove and fillet welds in the flat (first) and horizontal (second) positions.
Filler Metals: The F Number
This number is used to group filler metals used in welding procedures and welder performance qualifications.
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.
A 5F weld joint is a tube welded to a plate where the axis of the tube is horizontal and the plate is vertical. A 5F weld joint is a bit more challenging than a 2F. ... and the thing that makes it difficult is mainly body positioning.
A 4G welding certification demonstrates a welder's proficiency in the overhead position. ATS offers numerous services to fulfill our clients' needs, from welding sites to observations to quality testing.
The 5S concept consists of Sort (seiri), Set in Order (seiton), Shine (seiso), Standardise (seiketsu) and Sustain (shitsuke). One of the 5s elements is Straighten (seiton) where the systemize workplace and worker discipline to organize its work area become an important factor to improve work efficiency.
In the 5G position, the pipe is fixed at one or both ends and the welding operator must travel in one of two directions, either vertical-up or vertical-down. Depending on the location of the pipe, the application may also require welding either overhead or in a flat position.
TIG welding is the hardest form of welding to learn for a variety of reasons. The process of TIG welding is slow and takes time to get used to as a beginner. A TIG welder requires a foot pedal to feed the electrode and control the variable amperage while maintaining a steady hand at the welding torch.
Pipe welding is considered one of the more difficult processes for welders to master. In order to pass pipe welding tests, you must be able to join two cylindrical metal pipes together utilizing shielded metal arc welding or any number of other methods.
Pipeline welder
Pipeline welding is very challenging because the pipes are in fixed positions and can't move – so the welder must know how to work in many different and difficult positions to reach the area they need to weld.
F stands for fillet weld, while G is a groove weld. A fillet weld joins together two pieces of metal that are perpendicular or at an angle. A groove weld is made in a groove between workpieces or between workpiece edges.
The most common used codes or regulations are API Standard 1104, American Petroleum Institute— Used for pipelines, ASME Section IX, American Society of Mechanical Engineers—Used for pressure vessels and nuclear components, and AWS D1. 1, American Welding Society—Used for bridges, buildings, and other structural steel.
A more difficult certification, like the 6G welding test for a pipe standing at a 45-degree angle, takes anywhere from 12 to 18 months for a beginner. If you have more welding experience or can learn more quickly, then it may take less time to get certified.
The four basic welding positions are: flat, horizontal, vertical, and overhead.
Q: What voltages are used in the arc welding process? A: Arc Welding involves open circuit (when not welding) voltages which are typically from as low as 20 volts to as high as 100 volts.
1. Horizontal Rolled Welding—1G. If you see 1 in the position code, that means you'll be performing the easiest kind of pipe weld: a horizontal rolled weld. In this kind of welding, you weld from above the pipe and rotate along the X-axis as you complete the weld. If the pipes are small, you can rotate them yourself.
