Bend test sets

A range of bend test specimens that show the impact weld flaws can have on the structural integrity of a welded joint.

Our specimens are supplied as a set of five bars. Each bar measures 10mm wide x 200mm long and is available in either 12, 15 or 20mm wall thickness. They are manufactured to contain one flaw type from the list below and then each bar is bent until the weld starts to fail, and the flaw is exposed.

  • Bar 1 – Lack of side wall fusion (LoSWF)
  • Bar 2 – Slag
