Quick-reference welding positions chart

Start with the workpiece shape, then the letter and number. A 2G groove on a plate is not the same physical setup as 2G around a vertical pipe, even though both describe horizontal groove welding. On pipe, the key question is whether the workpiece rotates or stays fixed.

Workpiece	Code	Position	What to picture	Movement
Plate	1G	Flat groove	Plate horizontal; groove faces upward	Fixed
Plate	1F	Flat fillet	Upward-facing fillet trough	Fixed
Plate	2G	Horizontal groove	Upright plate; seam runs sideways	Fixed
Plate	2F	Horizontal fillet	Horizontal intersection of two plates	Fixed
Plate	3G	Vertical groove	Upright plate; seam runs vertically	Fixed
Plate	3F	Vertical fillet	Vertical intersection / inside corner	Fixed
Plate	4G	Overhead groove	Groove faces downward; weld deposited below	Fixed
Plate	4F	Overhead fillet	Inverted tee or corner; weld overhead	Fixed
Pipe	1G	Flat pipe groove	Horizontal pipe turns under arc at the top	Rotated
Pipe	2G	Horizontal pipe groove	Upright pipe; horizontal circumferential seam	Fixed
Pipe	5G	Mixed around pipe	Horizontal pipe stays still; weld travels around	Fixed
Pipe	6G	Inclined pipe groove	Pipe fixed at about 45 degrees	Fixed
Pipe	6GR	Restricted pipe test	Inclined pipe with access restriction ring	Fixed

Interactive reference

Explore the plate and pipe positions

Choose any diagram to get its explanation. The red arrow always points toward the floor (gravity), the blue arrow shows an illustrative direction of travel or orientation, and the orange line marks the joint. These are simplified original schematics, not drawings for setting a welding machine or preparing a qualification coupon.

Choose a diagram above

You'll see what the position code means, what stays fixed, and why gravity matters.

Note: 6GR is shown as an additional diagram so learners can compare restricted access with regular 6G. Ring dimensions and exact coupon construction are intentionally not provided; follow the applicable code and testing facility.

How to read a welding position code

Numbers describe position

On plate, 1 is flat, 2 horizontal, 3 vertical and 4 overhead. Pipe uses additional fixed setups: 5G for a fixed horizontal pipe and 6G for an inclined fixed pipe. Don't assume every numeral works identically across every joint type.

Letters describe the joint

G = groove: weld deposited into a groove between members. F = fillet: weld joining intersecting surfaces, often an inside corner. The R in the familiar 6GR test indicates a restriction near a tubular test weld.

Not the same as welding symbols: Position codes identify physical orientations. Welding symbols on a drawing communicate required weld design, size, location and other instructions. Try our welding symbols practice lab for that separate skill.

Plate welding positions: 1F/1G through 4F/4G

1: Flat

With the weld facing upward, the pool sits naturally in the joint. A 1G groove is a straight seam on horizontal plate; a 1F fillet is an upward-facing corner trough. This is often where beginners first learn to keep a consistent bead.

2: Horizontal

The seam goes sideways, but the face of a groove joint is upright. Gravity tends to pull the molten pool toward the lower edge. A 2F horizontal fillet typically forms where an upright plate meets a horizontal base.

3: Vertical

The seam runs up and down. Vertical-up and vertical-down are distinct approaches; the approved WPS and qualification govern which is used. Not every application permits switching direction just because both feel comfortable.

4: Overhead

The joint faces downward, with the welder beneath it. Gravity works against the molten pool, and falling hot metal adds a serious hazard. Overhead practice belongs in a properly supervised, protected welding environment.

Welding position does not dictate one universal machine setting. Process, filler classification, material thickness, transfer mode, joint design and the qualified procedure all matter. For example, Miller distinguishes conventional spray-transfer MIG from pulsed and short-circuit transfer in positional capability.

Pipe positions: rotated 1G versus fixed 2G, 5G and 6G

Pipe introduces a curved joint. Picture the cylinder's lengthwise axis separately from its circular weld seam. That's the mental trick: a horizontal pipe can be rotated for 1G or locked in place for 5G, creating radically different tasks.

1G pipe: rolling under the torch

The pipe lies horizontally and rotates around its lengthwise axis; the weld remains near the top. Think of a pipe spool on turning rolls. Being able to weld its top does not prove you can weld all the way around a fixed pipe.

2G pipe: upright and stationary

The pipe stands upright. Its circular seam sits in a horizontal plane, with the welder moving around the circumference. Unlike 1G, the workpiece does not rotate during welding.

5G pipe: fixed horizontal

The pipe is horizontal but secured against rotation. Starting from the bottom and moving upward, a welder passes through overhead, vertical and flat orientations. The approved weld progression controls how the work is performed.

6G pipe: fixed at 45 degrees

The pipe remains inclined at roughly 45 degrees as the welder circles the joint. Torch positioning and access are harder because the angle changes continuously. This is a demanding practice and performance-test configuration.

What makes 6GR different?

6GR is a restricted-access variation of the inclined pipe test, with a ring or obstruction placed near the joint. It is particularly relevant to certain complete-joint-penetration welds on structural tubular T-, Y- and K-connections under AWS D1.1. It is not an automatic requirement for every pipe welder or every ASME pressure-piping job. See the Steel Tube Institute's HSS welding position reference for the structural context.

The schematic does not specify ring thickness, setback, weld preparation or test tolerances. Those belong to the applicable edition of the code and approved qualification procedure, not a general-interest website.

Welding positions are not a universal certification

A position designation answers where the test weld is made, not every question about what the welder is allowed to produce. A welding performance qualification is evaluated against a specific procedure and governing code. The range of qualification depends on additional variables, such as the process, test assembly, filler and material requirements, progression and thickness or diameter restrictions as applicable.

3G + 4G plate

An AWS technical explanation describes combined 3G and 4G plate groove tests qualifying all production positions on certain nontubular structural shapes under its discussed AWS D1.1 example. That does not override other variables or turn it into a universal pipe qualification.

Passing a 6G pipe test

Passing a 6G test may demonstrate broad positional ability within the specific code's rules, but it does not automatically qualify another welding process, all metals, every thickness or every restricted-access connection. For credentials and testing routes, use our welding certification guide.

What actually happens in a welding qualification test?

The candidate prepares and deposits a weld using the specified test assembly and welding procedure. The completed weld is evaluated by the method and acceptance criteria specified by the relevant standard. Depending on the procedure, evaluation can involve visual examination and guided bend or other testing. There is no one universal "1/8-inch rule" that safely summarizes all acceptance criteria and exceptions.

For the AWS Certified Welder program, AWS describes hands-on, performance-based testing at an Accredited Test Facility and states that the program has no prerequisite course or prior-certification requirement. Welding school graduation and a passed qualifying weld are separate accomplishments. See AWS program requirements.

Position practice is hands-on, and safety isn't optional

These diagrams and questions explain terminology; they are not instructions for unsupervised welding. Out-of-position work can put the welder beneath hot metal, arc radiation and welding fumes. Welding also involves electrical, fire and gas hazards.

Training facilities should provide proper machine instruction, protective helmets/lenses, protective clothing appropriate to the hazard, safe equipment and ventilation. OSHA notes that protective clothing requirements vary by the size, nature and location of the work. Ask instructors what additional protection is used during overhead practice. OSHA: general welding requirements.

Where do students learn these positions?

Schools can organize practice differently, but public course descriptions show a useful progression: basic plate joints, vertical and overhead welding, then specialized pipe work as appropriate to the credential.

Austin Community College · Texas

ACC publishes welding syllabi covering beginning shielded metal arc welding (WLDG 1428), WLDG 1435 Introduction to Pipe Welding (API 1104), WLDG 2453 Advanced Pipe Welding (ASME Section IX), and WLDG 2179 Welder Qualification. Specific instructor syllabi can differ. See current course list.

Hobart Institute · Ohio

The Hobart Institute currently lists an advanced 4-week, 140-hour SMAW 6-inch pipe uphill course covering 2G, 5G and 6G, followed by a 2-week, 70-hour 2-inch 6G course with prerequisites. These are individual courses, not proof of a universal time-to-certification. Read individual course descriptions.

Lincoln Tech · Multiple campuses

Lincoln Tech's current welding-program overview emphasizes supervised shop training in SMAW, MIG, TIG, FCAW, cutting, fitting and blueprint reading. Specific positions, testing opportunities, program length and campus offerings should be confirmed at the campus, rather than assumed from a generic brochure. See program overview.

Your local training provider

Ask which plate and pipe positions the program actually teaches, how many supervised booth hours are included, what process and test code it uses, and whether third-party qualification testing is included in the tuition or costs extra.

Six questions worth asking a welding school

Do beginners practice flat, horizontal, vertical and overhead plate welds, and with which processes?
Is 5G or 6G fixed-pipe welding part of this particular credential or an advanced elective?
How many supervised shop hours are included, and how are students assessed?
What code, procedure and test position does any included performance test follow?
Does completion lead to a school credential, an external qualification, both, or neither automatically?
What are the full costs for PPE, materials, testing, retesting and tools, and how are outcomes reported?

Frequently asked questions

Which welding position is the hardest?

Many welders find overhead and fixed inclined 6G pipe demanding because gravity complicates puddle control and access changes around the joint. The hardest task also depends on the process, material, joint, test requirements and the welder's experience.

What is the difference between 5G and 6G?

Both involve a fixed pipe. In 5G the pipe axis is horizontal; in 6G it is inclined about 45 degrees. The inclined setup adds changing access and torch-angle challenges as you move around the seam.

What is the difference between 1G and 1F?

Both are flat positions. G means a groove joint between edges, while F means a fillet joint joining intersecting surfaces. The shape of the weld joint differs even if the puddle faces upward in both.

Does a 6G welding test qualify you for everything?

No. Qualification applies to a defined process, code and set of essential variables. Additional tests or qualifications may be needed for other processes, materials or restricted connections. See the welding certification guide.

Is this an official AWS welding practice exam?

No. This is a free, independent educational tool for recognizing welding positions and understanding basic qualification concepts. It does not issue credentials or assess actual welding performance.

Can I learn welding positions online?

You can learn what the positions mean and practice recognition online. Welding in those positions requires supervised hands-on practice with appropriate equipment, protective gear and ventilation.

Can I print the welding positions chart?

Yes. Use Print chart / save as PDF near the diagrams. Your browser's print dialog can print a reference sheet or save it as a PDF.
