This article focuses on everything you need to know about welding, from certifications, institutes that can prepare you for these credentials, and the types of certifications available.

What Are Welding Certifications?

Welding certifications are formal assessments that verify and prove a welder’s ability and knowledge of the principles. You can pursue most welding certifications online or as a practical demonstration.

Why Are Welding Certifications So Important?

Welding certifications prove that you have the necessary skills to do the job. Additional benefits include:

  • More job opportunities across different industries.
  • Decreased recertification costs.
  • Demonstration of important knowledge and the skills.
  • Proof of your ability to perform different welding procedures.
  • Higher job stability with permanent positions in the industry.

Welder Certifications Vs. Qualifications

There is a lot of confusion surrounding the difference between certifications and qualifications. To be clear, these terms are not interchangeable.

According to the American Welding Society, you can achieve a certification through a specific channel and process. However, the qualification test depends on the company or the contractor and the tests they choose for their job.

The goal of certifications is to meet the welding codes established by the AWS, ASME, and API. Qualification tests do not depend on codes but each company’s set of parameters such as weld process, base metal type, electrode type, weld position, and base metal thickness.

Certification agencies help you become a certified welder for that extra leverage when searching for jobs. Once you complete the certification, you will receive a certified welder card. Qualification is still necessary after you apply for a job.

The Most Prominent Organizations That Provide Welding Certifications

The three most prominent organizations that provide welding certifications in the U.S. are:

  • American Welding Society (AWS) – The American Welding Society is a non-profit organization that provides professional certifications and opportunities for collaboration in the welding industry. Get leading industry knowledge, resources, and tools for career success.

Certification organizations conduct tests to see the welder’s ability to work under the code. Most tests consist of:

  • Following the instructions and welding the metals in the required position.
  • Cutting the metal welded according to the instructions and preparing it for a bend test or another approved method for quality testing.
  • Performing bend tests and radiographic (x-ray) tests on the material.

Welding Certification Positions

The welding certifications depend on whether the welder is working on a plate or a pipe.

Plate Welding Certification Positions

There are two types of plate welding position:- fillet weld and groove weld. Most plate welding certifications are on a groove weld because this also qualifies you for fillet weld. The coding system to identify the welding position is:

1 – Flat position

2 – Horizontal position

3 – Vertical position

4 – Overhead position

F – Fillet weld

G – Groove weld

Using the coding system above, we’ve outlined the different positions below:

  • 1G plate welding certification position – This position has the plate in a beveled flat position. It is the most basic position.
  • 2G plate welding certification position – This position has the plate in a beveled horizontal arrangement. If you clear this test, you automatically cover the 1G position.
  • 3G plate welding certification position – This position has the plate in a vertical position. You can either start at the bottom and weld upwards or the other way around. The 3G test covers both 1G and 2G positions.
  • 4G plate welding certification position – This position has the plate in the beveled overhead position. The 4G position covers both 1G and 2G positions but not the 3G position.
  • 3G and 4G combo plate welding certification positions – It is also common to take 3G and 4G welding tests together.

Pipe Welding Certification Positions

The coding system for pipe welding certifications is as follows:

  • 1 – Horizontal position and rolled
  • 2 – Fixed vertical position
  • 5 – Fixed horizontal position
  • 6 – Fixed position at an angle of 45-degree
  • R – Restricted position
  • F – Fillet weld
  • G – Groove weld

Using the coding system above, we’ve outlined the different positions below:

  • 1G pipe welding certification position – The welder places the pipe in a horizontal position and rolls it while welding.
  • 2G pipe welding certification position – The pipe is in a vertical position and fixed, and the welding direction is horizontal.
  • 5G pipe welding certification position – The pipe is in an overhead position, horizontal, and fixed. The welding is vertical and flat, with a full transition of all three positions.
  • 6G pipe welding certification position – The pipe is in a 45-degree position and is fixed. There is an easy side and a hard side to this welding position. This position certifies you for pipe and plate welds in all positions and is for high-paying jobs.
  • Restricted pipe welding certifications and positions – This test checks your ability to weld in confined spaces.

There are three ways to limit access:

  • Unusual body position of the welder.
  • Using ceiling, walls, restrictive rings, and other obstacles to block access to the joint.
  • Blocking the visual access and forcing the welder to use a mirror for welding.
  • 6GR restricting ring-type welding position – This test position comprises an 18″ restrictive ring 1/2″ above the weld joint.
  • 6GR restricted boiler tubing position – This position consists of two boiler tubes, one on each side of the coupon with 1-inch of clearance. It is one of the most challenging tests. It would be best to weld half of it with your left hand and the other half with your right hand. It is not permissible to walk the cup.
  • 6GR box type restriction pipe welding position – Box type restricted welding is applicable in the shipping industry. The pipe is inside a welding booth with a steel grading ceiling in a 6G position. If you are right-handed, the pipe is on the right side of the booth, 12″ from the right wall, ceiling, and back wall. This makes the 3 to 12 o’clock positions almost inaccessible.

Welding Certification Processes

Standard processes for welding certification tests are:

  • GTAW (Gas Tungsten Arc Welding) or TIG welding
  • SMAW (Shielded Metal Arc Welding) or Stick welding
  • GMAW (Gas Metal Arc Welding) or MIG welding
  • FCAW (Flux Core Arc Welding) or Wire Wheel welding

Other welding processes in which you can get certifications are:

  • Brazing
  • Plasma welding
  • Laser welding
  • Soldering
  • Resistance welding
  • Stud welding
  • Submerged arc welding

Common Welder Qualification Test for Jobs

The welder qualification tests for jobs vary in positions, welding processes, and the type of welding inspection. While some jobs may require just the visual inspection, others may ask for a bend test and x-ray of the weld as minimum requirements.

Qualification Tests for Construction Jobs

Welder qualification tests are equivalent to and sometimes even more challenging than certification tests. Most construction jobs will likely ask for a 3G and 4G combo MIG welding test. They may also require either stick welding or flux-cored arc welding, or both.

Qualification Tests for Shipyard Jobs

Shipyard jobs ask for stick welders in the 3G and 4G combo welding positions. They do not allow weave beads. It is always an open root weld using ceramic backing tape. The flux cored arc welding test combines 2G, 3G, and 4G positions.

Qualification Tests for Power Plant Jobs

The most common test in power plant jobs is a pipe in the 6G position using a TIG root and hot pass. They will x-ray this weld and will not allow any grinding.

Nuclear and coal-fired power plant jobs require three tests. The first is a 2″ double heavy wall schedule 160 carbon steel pipe in the 6G position with a TIG root and hot pass, and the rest stick-welded with an E8018.

The second test is a 2″ double heavy wall schedule 160 carbon steel pipe in the 6G position that is completely TIG welded. The third is a 4″ thin wall schedule 5 or 10 stainless steel pipe fully TIG welded.
