Bend
This Bend test is designed to evaluate the quality of welds as a function of ductility in ferrous and nonferrous
products as evidenced by their ability to resist cracking during bending.
Reference:
3 Types of Bends:
A. Transverse side bend. The weld is transverse to the longitudinal axis of the specimen
which is bent so that either one of the side surface becomes the convex surface of the bent specimen.
B. Transverse face bend. The weld is transverse to the longitudinal axis of the specimen which is
bent so that the weld face becomes the convex surface of the bent specimen.
C. Transverse root bend. The weld is transverse to the longitudinal axis of the specimen
which is bent so that the weld root becomes the convex surface of the bent specimen.
Note: For more information please refer to the following publications:
AWS D1.2–D1.2M: 2003; API 5LC (R2006); API 1104 (R2010).
