What is the AWS D1.1 - 5G Welding Position?

The "5G" designation is a standard defined by the American Welding Society (AWS) and other codes like ASME. It's a fundamental certification for pipe welders.

• 5: Refers to the test position number.

• G: Stands for "Groove" weld, indicating that the test involves a beveled joint.

In the 5G position, the pipe is fixed in a horizontal axis and cannot be rotated. The welder must perform the weld by moving around the pipe, transitioning through all four primary welding positions:

• Overhead (4G) at the bottom of the pipe.

• Vertical-Up (3G) or Vertical-Down on the sides.

• Horizontal (2G) as you work around the circumference.

This unique combination makes the 5G test a comprehensive evaluation of a welder's skill and adaptability.

5G vs. 6G: What's the Difference?

Achieving a 5G welding certification is more than just passing a test; it's a powerful career-accelerator that showcases your elite skills and versatility. Employers across high-demand industries actively seek welders who hold this certification. It proves you can handle complex, real-world pipe welding scenarios with precision and confidence, translating directly to greater job security and a higher earning potential.

Master of All Positions

The 5G weld test is a rigorous "all-position" pipe welding qualification. Unlike tests that focus on a single orientation, the 5G position challenges you to seamlessly transition between overhead, vertical, and horizontal welding. This comprehensive test validates your ability to control the weld puddle and maintain a consistent travel speed and arc length, even as gravity constantly pulls on the molten metal. This level of proficiency is a key indicator of a truly skilled professional welder.

While the 5G position is challenging, the 6G position is considered the "all-encompassing" test. In the 6G position, the pipe is fixed at a 45-degree angle. This adds another layer of complexity, as there are no true flat or horizontal sections.

A 6G certification typically qualifies a welder for all other positions (1G, 2G, 3G, 4G, and 5G) as it requires the highest level of skill and puddle control. However, a 5G certification is often a prerequisite and a common requirement in its own right for many jobs. You can learn more on our dedicated 6G Weld Testing page.

Preparing for Your 5G Weld Test

Success in a 5G test comes down to preparation and practice. Here are the key steps to follow:

1. Know Your Code and Procedure

Before you even strike an arc, you need to understand the welding code you're testing to (e.g., AWS D1.1, API 1104, or ASME Section IX). The code will specify:

• Filler metal (e.g., E6010 for the root, E7018 for the fill and cap).

• Pipe dimensions (diameter and wall thickness).

• Joint configuration (bevel angle, root opening, and land).

• Welding process (SMAW, GTAW, etc.).

• Post-weld inspection requirements (visual, bend tests, or X-ray).

2. Practice, Practice, Practice!

The most common point of failure is the transition between positions. Spend time on each section of the pipe, focusing on:

• Root Pass Control: The root pass is the foundation of your weld. Maintain a steady hand and a tight keyhole, especially in the overhead and vertical sections.

• Body Position: Find a comfortable and stable position for each part of the weld. Use your elbows for support and move smoothly around the pipe.

• Weld Puddle Manipulation: Learn to manipulate the puddle to counteract gravity. Whether you're whipping, dragging, or weaving, consistency is key.

• Cleaning: Thoroughly clean each pass with a grinder, wire brush, or chipping hammer to prevent slag inclusions and lack of fusion.

3. Seek Professional Guidance

Working with experienced instructors or certified welding professionals can make all the difference. They can provide personalized feedback on your technique and help you identify and correct bad habits.

Ready to Achieve Your AWS D1.1 5G Pipe Welding Certification?

What is the hardest part of the 5G weld test?

Many welders find the "overhead" section at the bottom of the pipe to be the most challenging. Managing the weld puddle against gravity while maintaining a consistent travel speed requires significant skill and practice.

What welding processes and filler metals are typically used for a 5G test?

The most common process is SMAW (Shielded Metal Arc Welding). A popular combination of filler metals is an E6010 electrode for the root pass and an E7018 electrode for the fill and cap passes.

Does a 5G certification qualify me for all welding positions?

No, a 5G certification does not automatically qualify you for all positions. However, it does qualify you for the flat, vertical, and overhead positions on a pipe. To be certified for all positions, you would typically need to pass the 6G test.

How long is a 5G welding certification good for?

Welding certifications typically last for six months. To keep it current, you must weld using the qualified process every six months. Your employer is responsible for maintaining a record of your continuity.

Once you've completed your weld, the work is inspected to the applicable welding standard. The process typically involves a two-stage evaluation to ensure the weld is sound, strong, and meets all code requirements.

Visual Inspection

A Certified Welding Inspector (CWI) will perform a thorough visual inspection of your finished weld. They are looking for surface imperfections such as porosity, undercut, overlap, and proper bead profile. This initial step is crucial—if the weld fails the visual inspection, no further testing will be performed.

Destructive or Non-Destructive Testing

After passing the visual inspection, the test coupon will undergo further evaluation to check for internal defects.

• Destructive Testing (Bend Tests): This is the most common method. Sections of the pipe are cut out and bent in a jig to test the weld's ductility and fusion. The convex surface of the bent specimen is inspected for any cracks or discontinuities.

• Non-Destructive Testing (X-Ray): For certain codes, especially API 1104, the weld is often subjected to radiographic testing (X-ray). A radiograph provides an internal view of the weld, revealing any porosity, slag inclusions, or lack of fusion.

If the weld passes all of these tests, you have successfully qualified and your certification will be issued.

Higher Earning Potential & Career Growth

Holding a 5G welding cert demonstrates to employers that you have the advanced skills to perform critical, high-stakes work. This specialized expertise commands a premium salary and sets you apart from welders with only basic qualifications. Many professionals use the 5G certification as a foundational step toward more advanced qualifications, such as the coveted 6G certification, further expanding their career opportunities and increasing their income.

The Challenge of the 5G Test

Unlike a 2G weld test, where the pipe is vertical and the weld is purely horizontal, the 5G position forces you to manage the molten weld puddle against the constant pull of gravity. You must maintain consistent technique, arc length, and travel speed as your body position changes, which is a significant challenge.

The weld is typically performed in two halves, starting at the bottom (6 o'clock position) and working your way up to the top (12 o'clock position) from both sides.
