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.
How do you bend aluminum test?
In bend testing, a 1.5-inch-wide sample is cut so the weld is running across the width of the sample. Then the sample is bent around a specified radius, with either the root or the face of the weld in tension. The bend usually is made using a radiused plunger that pushes the sample down into a radiused female die.
What is a face bend test?
The bend test determines the quality a weld at the face and root of a welded joint. The specimen normally is bent 180 degrees. Face bend tests are made with the weld face in tension; root bend tests are made with the weld root in tension.
Is standard for bend test?
1.1 This standard specifies the method of conducting bend test for determining the ability of metallic materials to undergo plastic defor- mation in bending. It applies, to the bend test of test pieces taken from metallic products as apecilied in the relevant product standard.

Why bend test is done in welding?
The bend test is a simple, inexpensive qualitative test that can be used to evaluate both the ductility and soundness of a welded joint or less commonly parent material. It is often used as a quality control test for butt-welded joints, having the advantage of the simplicity of both test pieces and equipment.

How do you test Aluminium?
Check your metal by applying the magnet test again if you suspect that the metal is aluminum. Aluminum and tin can be mistaken for one another, but tin will stick to a magnet while aluminum will not. Tin also has a similar color to aluminum but shows a slightly duller finish.
How do you pass a bend test?
Why is bending test important?
What is the Purpose of Bend Testing? Bend testing a material allows for the determination of that materials ductility, bend strength, fracture strength and resistance to fracture.

Do you need to bend test aluminum for welding?
Almost all welding codes require bend tests for welding procedures and welder qualifications. These tests can cause more problems in aluminum than in steel. In bend testing, a 1.5-inch-wide sample is cut so the weld is running across the width of the sample.
Can you bend test aluminum with a plunger?
BendTesting Of Aluminum Is Different Than Bend Testing Steel. Most guided bend testing of steel is conducted with the use of a die and plunger arrangement often referred to as the plunger-type guided bend test. The plunger-type guided bend test is not recommended for testing aluminum.
How to test the bend coupons for butt welding?
For butt weld procedure and welder qualification testing the bend coupons may be oriented transverse or parallel to the welding direction. Below approximately 12mm material thickness transverse specimens are usually tested with the root or face of the weld in tension.
What is a bend test?
The type of bend test (root, face, or side) is determined by which surface of the weld sample (root, face, or side) is on the convex (outer) side of the bent specimen and, consequently, subjected to tension load during the testing operation.
