Clause 9 is basically a stand alone code.
You need a copy of the latest edition AWS D1.1 Structural Welding Code (Steel). Without the code book it is extremely difficult to do so. As of the writing of this guide, the cost of AWS D1.1/D1.1M:2020 Structural Welding Code – Steel is $509 for AWS members and $679 for non-members. Write a couple of prequalified WPSs and it pays for itself!
The AWS D1.1 Structural Welding Code (Steel) welder qualification plate tests consists of a groove weld with a 45-degree included angle. The plates are prepared to a knife’s edge and a ¼ in [6 mm] backing strip is used. The test for unlimited thickness will use plates that are 1 in [25 mm] thick. Anything […]

Hello Frankie. AWS D1.1 only provides information regarding SMAW low-hydrogen electrodes. Take a look at this article from Hobart. It provides good information on properly storing flux-cored wires. Most manufactures keep the boxes of unopened wire in a separate room with low humidity.
AWS D1.6, like AWS D1.1 (Steel) allows for the use of prequalified welding procedure specifications (PWSPs). This is advantageous because it can save fabricators a lot of time and money by providing an exemption from qualification by testing in accordance with Clause 6 – Qualification.
When qualifying a welding procedure specification (WPS) for fillet welds per Clause 4 of AWS D1.1 Structural Welding Code you must only perform a single test. You must do macroetches in three locations as shown below. It is assumed that if we can show root fusion at these three locations that our welding procedure is […]
