Welder certification project coverage issues

The welder's certification project GTAW-FeIV-6G-8/57-Fefs-02/10/12 means that the welder can weld iron materials with wall thicknesses from 8mm to 57mm under the GTAW welding process. The item considered for process specification requirements is GTAW-FeIV-6G-12/57-Fefs-02/10/12, which has a wall thickness ranging from 12mm to 57mm. Therefore, from the perspective of wall thickness, the welder's certificate covers the requirements of the process regulations (the wall thickness of the pipe does not exceed 16mm), and he can weld. However, this also requires consideration of other factors, such as whether the working environment and equipment meet the scope of the welder's certification. In actual operations, the welder's certification items are generally required to be completely consistent with the process regulations to ensure welding quality and safety. Therefore, it is best that the welder’s certification items are completely consistent with the process regulations, unless it can be ensured that the welder’s technical level and operational ability can meet the needs of the process regulations under the existing conditions. .

It is ok if the thickness of the workpiece does not exceed 16mm

8/57, shouldn’t 8 be the wall thickness, and shouldn’t 57 be the outer diameter of the pipe?

It’s clear from looking at this table, it’s just covered.

Items that do not require a certificate are exactly the same as those of the welder, as long as they can be covered. The wall thickness of the pipe does not exceed 16. If it can be covered, you can weld.

Don’t the welder’s certification items and process specifications need to be consistent? As long as the welder's certification project can cover the process regulations, right?

It doesn't have to be exactly the same as the process specifications, as long as it can be covered. GTAW-FeIV-6G-12/57-Fefs-02/10/12, the welder’s certification project GTAW-FeIV-6G-8/57-Fefs-02/10/12 The code name of the two projects of the poster is non-melting arc gas shielded welding, material austenitic stainless steel, construction welding Welding position is 45 degrees from bottom to top (this code can weld flat, vertical, horizontal, upward, and upward slopes), pipes or plates with a diameter of 25 or more, the first code (12/57) has no upper limit for weldable thickness, the second code (8/57) has a weldable thickness equal to or less than 16mm, welding wire filling (cannot be welded without welding wire filling), 02/10/12 are solid core welding wire, with shielding gas on the back, and DC positive connection.
