ASTM E190 is a widely used standard test method that assesses the ductility and quality of welds in metallic materials. This test method determines the ability of a weld to withstand bending without cracking or other forms of failure. It is an essential test for evaluating the integrity and performance of weldments in industries such as construction, manufacturing, and transportation. ASTM E190 evaluates the quality of welds as a function of ductility as evidenced by their ability to resist cracking during bending. Test results stated in inch-pound units are to be regarded as standard.

Introduction to ASTM E190
ASTM E190 establishes the standard test method for conducting a guided bend test to evaluate the ductility of welds. Ductility is a critical property that ensures the weld’s ability to withstand deformation and stress without failure. The ASTM E190 test method provides guidelines for performing a consistent and controlled bending test on weld specimens, allowing for the identification of potential weld defects, such as lack of fusion, incomplete penetration, or other discontinuities. The ASTM E190 test method covers a guided bend test for the determination of soundness and ductility of welds in ferrous and nonferrous products. The quality of welds is evaluated as a function of ductility as evidenced by their ability to resist cracking during bending.
ASTM E190 test method is useful for qualitative characterization, research, development, and specification purposes. We have the best network of testing labs in the USA to carry out ASTM E190 test for our clients.
ASTM E190 Test Method
The ASTM E190 procedure is as follows:
Guided Bend Testing
The guided bend test requires a specially designed bending apparatus that applies a controlled bending force to the weld specimen. The weld specimen is carefully positioned in the bending apparatus, and a gradually increasing force is applied until the specimen reaches the specified bend angle or shows signs of failure.
Visual Inspection
After bending, the specimen is visually inspected for any cracks, fractures, or other indications of failure. The size and nature of any observed defects are recorded.
ASTM E190 Specimens
Specimen details
ASTM E190 specimens are oriented to ensure that the weld fusion line or other critical areas are subjected to the maximum stress during bending.
Specimen dimensions
Welded joints or test plates are prepared according to specific dimensions, welding procedures, and requirements defined in the applicable welding codes or project specifications.
Specimen preparation
Specimen preparation guidelines include cutting, machining, or sampling techniques to obtain representative samples for testing.
ASTM E190 Results
The results of ASTM E190 provide information on the ductility and quality of the weld. A sound weld should exhibit sufficient ductility, without any visible cracks or significant defects, after undergoing the specified bending process. The absence of cracks indicates the weld’s ability to withstand deformation without failure.
