5. DETAILED REQUIREMENTS

A procedure qualification record shall be established for all Class A and B welds. The PQR shall contain all of the relevant information contained in the format example in Appendix A.

5.1 Welding consumables

5.1.1 Low hydrogen electrode storage

These covered electrodes shall be procured in hermetically sealed containers. After removal from the container, the electrodes shall be stored in an oven at a temperature to prevent moisture contamination.

5.1.1.1 Exposure

After hermetically sealed containers are opened or after electrodes are removed from drying or storage ovens, the electrode exposure before use shall not exceed the following values:

E70XX 4 hrs E80XX 2 hrs E90XX 1 hr E100XX ½ hr E110XX ½ hr E120XX ½ hr

5.1.2 Bare filler metal storage

Bare welding wire and welding rod shall be stored in a clean and dry environment. Heating may be employed if necessary to prevent moisture accumulation.

5.1.3 SAW flux

This flux shall be stored in a clean and-dry area. Unfused SAW flux may be reused.

5.1.4 Identification

Filler metal and flux shall be properly identified.

5.1.4.1 Covered electrodes

Each covered electrode shall have distinguishable color code, type designation, or classification number marking. If markings are destroyed or missing, electrodes shall not be used.
