Why Bend Testing Matters
Bend Testing is a fundamental method for determining the ductility and formability of metals. By bending a specimen over a specified radius and inspecting the outer surface for cracks, engineers can confirm whether a weld or material meets stringent safety, compliance, and performance requirements.
This test provides insight into:
- Ductility and fracture resistance — ability to withstand deformation without failure.
- Formability — performance in shaping, welding, or fabrication processes.
- Weld quality — detection of cracks, lack of fusion, or inclusions.
- Mechanical behavior — modulus of elasticity and bending strength under applied load.
Bend Testing Capabilities
AADFW supports a wide range of Bend Testing configurations and specimen types, ensuring compliance with ASTM, AWS, ASME, and MIL standards.
- Face, Root & Side Bend Testing – Evaluates ductility and crack resistance of welded joints, with tensile stresses applied to weld face, root, or cross-section.
- Three-Point Bend Testing – Single central load to measure stiffness and bending strength.
- Four-Point Bend Testing – Even distribution of load across two inner points to reduce stress concentrations; ideal for brittle or heterogeneous materials.
- Guided Bend Testing – Bends specimens to prescribed angles, typically 180°, for weld procedure qualification.
- Coating & Adhesion Bend Testing (T-Bend) – Verifies coating integrity and adhesion after deformation.
- Custom Bend Fixtures – Interchangeable rollers and adjustable setups for varied specimen geometries.
- Volume Testing – Capable of handling both single specimens and large lot sizes efficiently.
Sample Types We Test:
Machined coupons, weld samples, fasteners, wire, cable, tubes, pipes, plates, beams, and structural bars. If needed, our team can provide guidance on coupon preparation to meet ASTM or MIL requirements
