QW-321.3(b) At the option of the manufacturer, the welder who
has failed the production weld alternative test may be
retested by examining additional weld areas equal to twice
the required length or number of pipe circumferences of
the same or consecutively made production weld(s) speci-

the welder is qualified and the area of weld on which he
had previously failed the test shall be repaired by him or
another qualified welder. If this length does not meet the
examination standards, the welder has failed the retest and
all of the production welds made by this welder shall be
examined completely and repaired by a qualified welder
or welding operator.
