The orientation of the welds with respect to the horizontal and vertical planes of reference is classified into four positions, namely, flat, horizontal, vertical, and overhead.
Post-Weld Heat Treatment Root Bend 2 Either the face- and root-bend tests or the side-bend tests may be used for thicknesses from 3? The notch shall be cut normal to the material surface in the heat-affected zone to include as much heat-affected zone as possible satm the resulting fracture Fig.
Qualification under any F number up to and including F4 shall qual a welder for all lower F numbers. Combining values from the two systems may result in nonconformance with this practice. The welder or operator asym performing the procedure qualification test is automatically qualified for performance. Types of Tests s488. Originally published as A 63 T. Preparation of Test Plate 5. Groove dimensions as shown in Fig. P-number designations in the ASME grouping of base metals for qualification may be different than the category numbers listed in Table 1.

A suggested ashm for recording such information is shown in Fig. A Indicate minimum distance for local preheating. ASTM D e1. Requalification of Welders and Operators The other two surfaces shall be called the face and root surfaces, the face surface having the greater width of weld. When two base materials having different category astmm are welded together, a procedure qualification must be performed for the combination.
