Bend test on weld overlay procedure qualification

[TommasoDG]

Hello all,

I need to perform the follow additional bend test for a particular qualification:

Three side bend specimens shall be machined from the test piece heat treated to the
minimum PWHT condition. Specimens shall be oriented transverse to the welding
direction.
1) Thickness of the specimens shall be twice the thickness of the deposited overlay and
shall contain the entire overlay thickness, bond line, and a thickness of the base
material equal to the thickness of the deposited overlay.
2) Width of the specimen shall be a minimum of 0.75 inches (19 mm).
3) Length of the specimens shall be a minimum of two inches (50 mm).
4) Machined specimen shall be bent around a 0.5-inch (13-mm) diameter mandrel with a
bead-to-bead bond line at the middle of the bend.
5) No cracks or lack of fusion defects are acceptable on the convex Surface

Have you some more information about this (i.e. angle of bend, ASTM reference etc.)

Thank you in advance

The information is complete as stated above for performing transverse side bend testing;

Machined specimen shall be bent around a 0.5-inch (13-mm) diameter mandrel with a
bead-to-bead bond line at the middle of the bend.

Review ASME B&PV Code Section IX for bend testing application.
