REVEAL DEFECTS BY BENDING DEFORMATION
Bend testing is commonly used to determine the ductility of the material or weldment. The test provides qualitative data on the ductility of the bent area of interest, directly reflecting the soundness and quality of the material or weldment. These characteristics are vital considerations in any engineering design in the Construction, Offshore, and Oil & Gas industries. This is mainly because bend tests provide qualitative data on the ductility of the bent area of interest, directly reflecting the soundness and quality of the material or weldment.
Our testing experts perform the bend test by deforming the specimen to a specified angle resulting in a concave surface (bend). The concave surface of the bend specimen is then visually inspected in detail for any defects or discontinuities. In the context of reinforcement bars and wire meshes, bend and rebend tests use similar operating principles. However, rebend tests require an additional step of rebending the test specimen back to a specified angle after the first bend.
Professional Testing Services Pte Ltd has decades of experience with Bend Testing of:
- Reinforcement Bars
- Wire Meshes
A myriad of materials requires bend tests to be performed, typically in the form of a sectioned bend test or bending a full-sized pipe. In general, these ductility tests assist in certifying material specifications and grades.
On the other hand, the bend testing of welds is essential for the qualification of Welding Procedure Specifications (WPS) and Welder Performance Qualification Tests (WPQT).
Strength is not the only desirable characteristic in reinforcement bars and wire meshes, as ductility is equally critical to function as the backbone of structures in construction. Thus, bend and rebend tests serve as crucial indicators for this purpose.
Application of Bend Test
Ease of the specimen preparation
Specimen undergo extensive plastic deformation, so any defects in materials are revealed
The angle of bend can be 90 degrees, 120 degrees or 180 degrees depending on the test standard
