Base Metals

Base Metal: Enter the base material used in the test. This is the metal or alloy that is welded, brazed, or cut. Most related fields will be automatically completed if the material is selected from the Material Browser. 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.

Group: This field will be automatically completed based on the chosen material, however a different Group Number may be manually selected.

Thicknesses: The minimum and maximum thickness in the Groove, Fillet, and Plug/Slot fields default to their qualified ranges. These values may be reduced within the qualified range.

Diameter: The pipe diameter defaults to the qualified minimum and maximum ranges. These values may be reduced within the qualified range.

Base Metal notes: Enter additional notes about the base metal.

Preheat

Minimum preheat temperature: The minimum temperature in the weld joint preparation immediately prior to the welding; in the case of multiple pass welds, this refers to the minimum temperature in the section of the previously deposited weld metal immediately prior to welding.

Min. interpass temperature: The lowest temperature in the weld joint immediately prior to welding; in the case of multiple pass welds, this refers to the lowest temperature in the section of the previously deposited weld metal immediately before the next pass is started.

Max. interpass temperature: The highest temperature in the weld joint immediately prior to welding; in the case of multiple pass welds, this refers to the highest temperature in the section of the previously deposited weld metal immediately before the next pass is started.

Preheat notes: Enter additional notes about the preheat process.

Postweld Heat Treatment

PWHT: Select whether or not a post-weld heat treatment will be performed.

Temperature: Enter the temperature of the post weld heat treatment.

Holding time: Enter the actual post weld heat treatment time. This should be expressed in hours and decimals; for example, record a PWHT time of 4 hours and 15 minutes as 4.25.

PWHT notes:  Enter additional notes about the PWHT that should be included with this WPS.
