What Is a 3G and 4G Welding Test
A 3G and 4G welding test refers to specific types of welding certification tests that are conducted to assess a welder’s skill level and ability to produce quality welds.
The “G” in 3G and 4G represents the welding positions in which the test is conducted, namely vertical up (3G) and overhead (4G).
These tests typically involve welding a specified joint configuration using a particular welding process, and the welds must meet certain criteria to pass the test.
Passing a 3G or 4G welding test demonstrates the welder’s proficiency in executing welds in challenging positions.
Did You Know?
1. The term “3G” in welding refers to a 3G position, which is a vertical uphill welding test position.
2. A 3G welding test is often regarded as one of the most challenging positions because the welder must weld upwards against gravity.
3. On the other hand, “4G” in welding stands for a 4G position, which is a horizontal welding test position.
4. Unlike the 3G test, the 4G test requires welding in the flat position, and it is considered less demanding in terms of welding skill.
5. Both 3G and 4G welding tests are commonly used to certify welders’ skills, ensuring their competence in various welding positions.
Introduction To 3G And 4G Welding Tests
Welding is a fundamental skill required in various industries, including construction, manufacturing, and automotive. As a welder, it is crucial to possess the necessary certifications to validate your expertise and ensure the quality and integrity of your work.
One such certification is the 3G and 4G welding test, which evaluates a welder’s ability to perform specific welds in different positions and on various thicknesses of metal.
In this article, we will explore the intricacies of 3G and 4G welding tests, understand their importance, and learn how to successfully pass them.
Understanding The Significance Of 3G And 4G Welding Certifications
Welding certifications, particularly the 3G and 4G certifications, hold significant value for professional welders. These certifications not only enhance their career prospects but also showcase their expertise and ensure the safety and quality of their work.
The 3G certification refers to the vertical-up welding position, while the 4G certification evaluates the overhead welding position. These positions are considered more challenging, as gravity has a more significant impact on the weld pool and overall welding process. Therefore, achieving these certifications demonstrates a welder’s abilities to tackle more complex and demanding projects.

- 3G and 4G certifications
- Benefits
- Enhance career prospects
- Showcase expertise
- Ensure safety and quality of work
“These certifications not only enhance their career prospects but also showcase their expertise and ensure the safety and quality of their work.”
Key Differences Between 3G And 4G Welding Tests
The 3G and 4G welding certifications assess a welder’s skills in different positions. There are several notable differences between these two tests:
-
The 3G welding certification is performed in the vertical-up position, where the weld is done against gravity. In comparison, the 4G certification is performed in an overhead position.
-
The 3G test typically involves welding on a fixed, vertical plate, while the 4G test requires welding on an overhead horizontal plate.
-
The 4G certification goes a step further by demanding the welder to switch between vertical, horizontal, and overhead positions. This additional complexity makes the 4G test more challenging and requires higher skill levels.
Overall, while both certifications evaluate welding skills, the 4G test presents greater difficulty due to the need to weld in multiple positions.
- Summary:
- 3G Welding Certification:
- Position: Vertical-up
- Plate: Fixed, vertical
- 4G Welding Certification:
- Position: Overhead
- Plate: Overhead horizontal
- Additional demand: Switching between vertical, horizontal, and overhead positions.

Frequently Asked Questions
What is 3G and 4G welding?
3G and 4G welding refer to specific positions and types of welds. 3G welding indicates a vertical groove weld, while 4G welding refers to an overhead groove weld. The numbers in 3G and 4G signify that the welds are performed in vertical and overhead positions, respectively. These positions require specific techniques and expertise to ensure the quality and strength of the weld joints.
What is 4G welding?
4G welding, also referred to as the overhead position, is a welding technique that involves welding the underside of a workpiece positioned horizontally. This position presents the most challenging conditions for welders as they have to combat the effects of gravity on the filler metal and weld bead deposition. With the workpiece positioned overhead, welders need to exercise precise control and skill to ensure efficient and high-quality welds. The 4G welding position demands a thorough understanding of the welding process and the ability to adapt to challenging conditions to achieve successful welds on horizontal surfaces.
What is a 3G weld test?
A 3G weld test is a comprehensive examination conducted by ATS to evaluate the quality of a weld, including the materials used and the welding technique employed. It specifically focuses on welds that involve a combination of different types, positions, and joints. Fillet (F) and groove (G) welds, which join two materials together, are the most frequently encountered weld types. The 3G weld test helps to identify any flaws or defects in the weld, ensuring that it meets the required standards and specifications. With its ability to uncover deficiencies, this test plays a vital role in guaranteeing the strength and integrity of the welded component or structure.
What is the difference between 3G and 4G weld test?
The main difference between a 3G and 4G weld test lies in the position in which the weld is performed. In a 3G weld test, the welder is required to perform a vertical groove weld, meaning the weld joint is placed in a vertical position. This test evaluates the welder’s ability to effectively weld in a vertical direction, which presents its own set of challenges. On the other hand, a 4G weld test focuses on overhead groove welding, where the weld joint is positioned in an overhead or flat position. This test assesses the welder’s skill in completing welds in an overhead position, which can be more demanding due to different angles and gravity’s influence.
Both the 3G and 4G weld tests require different techniques and expertise due to the varying positions of the weld joints. Welders must adapt to these different positions and understand the unique challenges each presents. The 3G test evaluates vertical welding skills, while the 4G test assesses overhead welding skills. Therefore, welders need to be versatile and proficient in both positions to excel in their craft.
