The dimensions of the welding groove are not essential variables of the welding procedure.
Where the material thickness permits, the axis of a heat-affected zone specimen may be inclined to allow the root of the notch to align parallel to the fusion line Fig. Metric Equivalents Y 8 [mml t, in. This abstract is a brief summary of the referenced standard. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
A88 side of the specimen turned toward the gap of the jig shall be the face for face-bend specimens, the root for root-bend specimens, and the side with the greater number of defects, if any, for side-bend specimens. Who by virtue of these tests meets the welder performance qualification.
A Indicate the number for controlling the maximum width. A number in parentheses indicates the year of last reapproval.
Types of Tests 6. Single or Multiple Pass: The welder or operator successfully performing the procedure qualification test is automatically qualified for performance.
Surfaces of backing plates when used asym also meet the same cleanliness requirements. For welding processes using wire, indicate wire diameter, wire feed speed, and current requirements. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
