10 in. (250 mm) min.

GENERAL NOTE: Mark the coupon into ten equal length specimens, label one end of the coupon D‐1 the other end D‐2. Cut the 10 in.

(250 mm) coupon (transverse to the weld length) into pieces 5 in. (125 mm) long each.

(1) Transverse Weld Cross Section Instructions

(a) Cut five specimens each approximately 1 in. (25 mm) in length from the coupon labeled D‐1 and discard the piece marked D‐1.

(b) Mark the remaining four specimens T‐1 through T‐4, prepare the specimens as detailed in (2)(b)(-1) below for examination, adjacent faces at the cut shall not be used.

(2) Longitudinal Weld Cross Section Instructions

(a) Cut five specimens each approximately 1in. (25mm) in length from the coupon labeled D‐2 and discard the piece marked D‐2.

(b) Mark the remaining four specimens L‐1 through L‐4, cut the specimens at approximately 1/3 of the weld width from the weld centerline through the length of each specimen in the longitudinal weld direction. Discard the four specimens containing approximately the 1/3

weld width, the remaining four specimens containing approximately the 2/3 weld width shall be prepared as detailed in (-1) below for

examination.

(-1) The specimens shall be smoothed and etched with a suitable etchant (see QW-470) to give a clear definition to the weld metal

and heat‐affected zone.
