Requirements For A 5G Welder (E6010 / E7010) in Yanbu

Requirements for a 5G Welder (E6010 / E7010)

✅ Applicable Standards

Employers or test labs usually refer to one or more of the following codes for pipe welding qualifications:

✔ API 1104 – common for pipeline welding and repair welder qualification tests.

✔ AWS D1.1 / D1.1M – structural welding code that covers pipe when referenced by project specs.

✔ ASME Section IX – welding procedure and welder qualification for pressure-boundary applications.

Each standard has specific acceptance criteria and test requirements.

???? Electrode Requirements

E6010 – Typically used for the root pass because of its deep penetration and fast freeze behavior, ideal for vertical-down.

E7010 – A cellulosic electrode similar to E6010 but designed for higher strength pipe applications and also suitable for vertical down fill passes.

Both are AWS A5.1 classified electrodes and work on DC+ (DCEP) polarity for best penetration.

???? Performance Test Details

These are typical components of a 5G welder qualification test:

???? 1. Test Joint

Weld a full-circumference butt weld on a pipe (often ~8″–12″ diameter depending on code and employer).

Pipe must be fixed (not rotated) — this ensures you weld all positions around the pipe.

???? 2. Technique

Root pass: usually done with E6010 or E7010

Fill / cap passes: depending on spec, the same or often E7018 in some codes — but jobs focused on downhill SMAW sometimes use E7010 for fill/cap too.

Note: Changing filler metal group or direction of travel (up/down) without requalification may invalidate the test under some standards.

???? Test Inspection Methods

After welding, the test coupon is evaluated by:

???? 1. Visual Inspection

✔ Weld appearance: no cracks, drips, lack of fusion, or excessive undercut.

✔ Smooth transitions between passes.

???? 2. Mechanical or NDT

Depending on the code being used:

Guided Bend Tests (common in AWS/ASME) — checks fusion and ductility.

Radiographic (X-ray) or ultrasonic (common in API 1104) — checks internal soundness.

If these tests pass, the welder receives a Welder Performance Qualification for 5G in the specified process (SMAW) and electrodes used.

???? Qualification Scope

Once passed:

✔ You are qualified to weld in 2G, 3G and overhead positions on pipe for the tested process.

✔ You are qualified on the same electrode group and direction you tested on; changing to different electrodes or a different progression direction may require requalification.

???? Certification Validity

Many codes or employers require continuity — you must weld using the same process at least once every 6 months to keep your qualification valid.
