Joint Type and Base Material Information

Types of joints qualified: Lists the type of welds the welder is qualified to perform based on ASME Section IX. A common value would be "Groove and fillet welds".

ASME Rated: Select this box if the material has been rated by the ASME.

Base metals welded: Enter the base material used in the test. This is the metal or alloy that is welded, brazed, or cut. Selecting a material as the "Base Metal 1" will select that material for "Base Metal 2" as well. However, another material may then be selected or entered independently for either field. The material with the lowest P- or S-Number should be entered first, as should an unrated metal.

The note will depend on the kind of weld being tested.
