GENERAL NOTES:

(a) For P‐Numbers, see QW/QB-422; for F‐Numbers, see QW-432.

(b) For guided‐bend jig configuration, see QW-466.2, QW-466.3, and QW-466.4.

(c) The weld and heat‐affected zone, in the case of a transverse weld bend specimen, shall be completely within the bend portion of the

specimen after testing.

(d) For materials with less than 3% elongation, a macro‐etch specimen shall be used in lieu of bend test at each bend test location. Acceptance criteria shall be in accordance with QW-183(a).

(e) Figure QW-466.3 shows the recommended method of testing aluminum weldments.

NOTE:

(1) The dimensions of the test jig shall be such as to give the bend test specimen a calculated percent outer fiber elongation equal to at

least that of the base material with the lower minimum elongation as specified in the base material specification.



The following equation is provided for convenience in calculating the bend specimen thickness:

GENERAL NOTES:

(a) See Figure QW-466.1 for jig dimensions and other general notes.

(b) Dimensions not shown are the option of the designer. The essential consideration is to have adequate rigidity so that the jig parts will

not spring.

(c) The specimen shall be firmly clamped on one end so that there is no sliding of the specimen during the bending operation.

(d) Test specimens shall be removed from the jig when the outer roll has been removed 180 deg from the starting point.

NOTES:

(1) Either hardened and greased shoulders or hardened rollers free to rotate shall be used.

(2) The shoulders or rollers shall have a minimum bearing surface of 2 in. (50 mm) for placement of the specimen. The rollers shall be high

enough above the bottom of the jig so that the specimens will clear the rollers when the ram is in the low position.

(3) The ram shall be fitted with an appropriate base and provision made for attachment to the testing machine, and shall be of a sufficiently

rigid design to prevent deflection and misalignment while making the bend test. The body of the ram may be less than the dimensions

shown in column A of Figure QW-466.1.

(4) If desired, either the rollers or the roller supports may be made adjustable in the horizontal direction so that specimens of t thickness

may be tested on the same jig.

(5) The roller supports shall be fitted with an appropriate base designed to safeguard against deflection and misalignment and equipped

with means for maintaining the rollers centered midpoint and aligned with respect to the ram.
