QW-153.1 Tensile Strength
......In order to pass the tension test, the specimen shall have a tensile strength that is not less than
(a) the minimum specified tensile strength of the base metal; or
(b) the minimum specified tensile strength of the weaker of the two, if base metals of different minimum tensile strengths are used; or
(c) the minimum specified tensile strength of the weld metal when the applicable Section provides for the use of
weld metal having lower room temperature strength than the base metal;
(d) if the specimen breaks in the base metal outside of the weld or weld interface, the test shall be accepted as
meeting the requirements, provided the strength is not more than 5% below the minimum specified tensile strength of the base metal.
(e) the specified minimum tensile strength is for full thickness specimens including cladding for Aluminum Alclad
materials (P‐No. 21 through P‐No. 23) less than 1/2 in.(13 mm). For Aluminum Alclad materials 1/2 in. (13 mm)
and greater, the specified minimum tensile strength is for both full thickness specimens that include cladding
and specimens taken from the core.
