Mechanical tests used in procedure or performance qualification are specified in
QW-141.1 through QW-141.5.
QW-141.1 Tension Tests. Tension tests as described in QW-150 are used to determine the ultimate strength of groove‐weld joints.
QW-141.2 Guided‐Bend Tests. Guided‐bend tests as described in QW-160 are used to determine the degree of soundness and ductility of groove‐weld joints.
QW-141.3 Fillet‐Weld Tests. Tests as described in QW-180 are used to determine the size, contour, and degree of soundness of fillet welds.
QW-141.4 Notch‐Toughness Tests. Tests as described in QW-171 and QW-172 are used to determine the notch toughness of the weldment.
QW-141.5 Stud‐Weld Test. Deflection bend,hammering, torque, or tension tests as shown in Figures QW-466.4, QW-466.5, and QW-466.6, and a macro‐examination performed in accordance with QW-202.5, respectively, are used to determine acceptability of stud welds.
