What tables are used to specify the range of thickness and diameter qualifications from procedure qualification tests?

• A. Tables listing thickness and diameter qualification ranges
• B. Welding consumable supplier tables
• C. Maintenance frequency tables
• D. Job scheduling tables

Answer: (A)

The main idea here is that the qualification tables set the scope of what a welding procedure has been proven to handle. These tables list the thickness ranges and diameters for which a procedure qualification test demonstrates acceptable welds. They define the boundaries within which a Procedure Qualification Record (PQR) and the Welding Procedure Specification (WPS) are considered valid. If production involves work outside those specified thicknesses or diameters, the procedure may not be qualified for those dimensions and another qualification test or an adjusted approach would be needed. In short, these tables document the exact size ranges the qualified welding procedure can safely cover, tying the qualification to real fabrication sizes. The other types of tables don’t determine this scope—they relate to consumables, maintenance, or scheduling, which don’t define the qualified dimensions for a PQ.
