The guidedbend specimens shall have no open discontinuity in the weld or heataffected zone exceeding 18 inch (3 mm), measured in any direction on the convex surface of the specimen after bending. A new test method called "Bead Bend Test " for evaluation of the hydrogen-assisted cold cracking (HAC) susceptibility of multi-layer welds will be presented. The main advantage of this test is the possibility of evaluation of weldments that are established by using real welding procedures. The concept of a bend test for welds is simple two plates are welded together and a flat strap of metal is cut from the welded plates. Next, the flat strap of a prescribed size is bent into a U-shape, stretching the material on the outer surface of the "U," while compressing the material on the inside surface..

A bend tests can provide information on both the soundness and ductility of a weld. This type of test is a "Destructive Test" so it is not used on welds that you want to put into use later. The test is done by bending a strip of the material to a certain radius which stretches the outer surface of the material to a point where it "yields".
