Learn about bend testing, a destructive test to determine the strength and ductility of materials. Find out the different types of bend tests, such as transverse, longitu. Bend Test in welding has different types to test the material in different conditions such as testing in longitudinal, transverse (for base metal or weld coupons), and face or root . A longitudinal bend test is performed on the test specimen. This test is extracted in the longitudinal direction of the sample piece.

Types of Bend Tests Bend tests may be categorized as Guided Bend Test; Semi-Guided Bend Test; Free Bend Test; Bend and FlattenFor longitudinal bend testing of butt welds, the test specimen shall be taken longitudinally from the welded joint of the manufactured product or from the welded test piece. The location and orientation of bend test specimens of cladding material shall be specified by the application
In the Guided bend test the test specimen is wrapped around a former of a given diameter as per the test specification. . In Figures, a, b, and c below, the dimensions of the Face bend Root transverse bend, and Longitudinal bend specimen are shown.

Various bend tests are used to evaluate the ductility and soundness of welded joints. However, the guided bend test is most commonly used in welding procedures and welder performance tests. This method is good at determining liner fusion defects, which often show up on the plate surface during the testing procedure.
Berdasarkan posisi pengambilan spesimen, uji tekuk bending dibedakan menjadi 2, yaitu transversal bending dan longitudinal bending. Apabila kedua jenis pengujian tersebut digunakan pada benda hasil pengelasan, maka pemotongan area pengelasan harus disesuaikan dengan jenis pengujiannya. . Uji Tekuk ( Bending Test ) merupakan salah satu bentuk .Guided bend specimens may be longitudinal or transverse to the weld axis. Transverse Bend-testing specimens have the weld parallel to the axis of bending. . Standard Test Method for Guided Bend Test for Ductility of Welds ASTM International .Figure 4 — Longitudinal face/root bend test specimen for a butt weld (LFBB and LRBB) 3.5 longitudinal root bend test specimen for a butt weld LRBB specimen where the direction is parallel to the butt weld direction and where the root is in tension Note 1 to entry: See Figure 4. 3.6 face bend test specimen for cladding without a butt weld FBCDownload scientific diagram | A diagram showing the method of testing longitudinal bend on specimens. from publication: Effects of Operating Parameters on the Static Properties ofPulsed Laser .
tiate the four methods of bending covered in these test methods. The two semi-guided bend test procedures provide radiused surfaces over which the bend is formed. The results obtained by different test procedures may not be the same, especially for material with a tendency to crack or fracture. 3.5 The test is completed when the designated angle of3.3.1 Longitudinal tests use a specimen with its long dimension aligned with the processing direction such that the bend is . 3.7.1 The semi-guided bend test is made by applying a force transversely to the specimen’s long axis in the portion that is being bent. Transverse Tensile Test and ; Longitudinal Tensile Test (all weld tensile tests). 3. . FREE-BEND TEST FOR WELD TESTING. Free Bend Test measures the ductility of the weld metal in a butt joint in a plate or pipe in .
In applied mechanics, bending (also known as flexure) characterizes the behavior of a slender structural element subjected to an external load applied perpendicularly to a longitudinal axis of the element.. The structural element is assumed to be such that at least one of its dimensions is a small fraction, typically 1/10 or less, of the other two. [1] . The 2" dimensions are from the longer (30" or 36" long) test plate joint for the longitudinal test specimens plate joint to the left of the 15" test plate joint. . up for discussion knowing full well that a 2" side bend test didn't make sense because if one looks up the term "Side bend test"in AWS A3.0 the definition is: "A test in which the .The bend test is a straightforward and low-cost qualitative method for determining a material's ductility and structural integrity. A mechanical test called bend testing is frequently used to evaluate a material's ductil ity and structural integrity, especially with regard to metals and alloys. This test provides important information about a material's capacity to sustain applied loads .
