ASTM E190 describes requirements for guided bend testing of welded materials. The guided bend test on welds is designed primarily for metal plates and pipes and provides a quality control check that helps determine the ductility of the weld and the effectiveness of the welding process. During the bend test, the material containing the weld is supported on both ends by the test fixture, while a load is applied at its center point.

Materials Testing System

For ASTM E290 testing we recommend using HST WAW-E Series and a 3 point bending test fixture. This fixture allows for adjustment of the support span and is supplied with various sizes of loading mandrels to accommodate different specimen thicknesses. The loading supports are held together with two tie rods to provide extra stiffness during loading. The dual test space load frames allow the bend test fixture to be positioned in the lower compression test space. Any tensile testing can also be accomplished in the upper tensile test space.
