  • The Guided Bend Test – Welding Classroom

    2018-9-22 · One of the tests used to determine the soundness of weld metal is a bend test. A bend test can take a few forms and may have to meet different requirements. For the purpose of this short piece of information, we will talk about the “Guided Bend Test” as opposed to the “Free Bend Test”. Here is a closeup video of a students GMAW Side bend.

  • Guided Bend Test of Metal Welds

    2021-7-19 · Guided bend tests provide a quality control check that helps determine the ductility of weld metal at the face and root of a welded joint. A guided bend test sample containing the weld is located at its center point while being supported by lower anvils. It is bent 180 degrees and the sample is visually checked for cracks or defects.

    2009-9-26 · The thickest bend specimen I have seen is 3/8'. Once the base metal thickness exceeds 3/8', side bends are used which are 3/8' wide x the base metal thickness. I think 3/4' is the maximum base metal thickness allowed for face/root bends, but I've never seen anyone choose to do a face/root bend on material over 1/2' thick.

  • Bend Testing - TWI

    When tested in a standard guided bend tester, primary bending will occur in the weakest material. The effective radius in the bend can become so small that the maximum elongation property of the material is exceeded, resulting in fracture. For mandrels larger than 1/2 inch, a knurled surface is used to drive the specimen being tested.
