4G Welding Certification

Welding certification requires a welding procedure or a qualification test. Certification is offered by a variety of different organizations and the requirements will vary by the certifying body.

Identification

Welding certifications are identified by the numeral and the letter. The numeral refers to the position; 4 indicates the overhead position. The letter will either be an F, for fillet groove, or G for a groove weld.

Considerations

For a person to pass a 4G welding certification test the sample must meet a visual inspection as well as an X-ray or bend test to check for significant welding defects.

Significance

To perform certain welding jobs requires certain welding certifications, specific to the type of material, and the position and type of pipe. A certified welder will have demonstrated the ability to perform that type of weld to a prescribed level of professionalism and will therefore have better job opportunities and advancement potential within a company.
