The bend test is being used in welder performance tests to substitute the NDT.Bend tests may bend the weld towards the face, towards the root, or sideways. The most common is a guided bend test as opposed to a free bend test. Some materials are required by certain codes to be bent at specific radii. The property that dictates this is often the required "elongation" in the specimen.- face bend test pieces, when the surface in tension con- tains the largest width of the weld; - root bendtest pieces, when the surface in tension con- tains the root of the weld.

You may perform a radiography or ultrasonic testing to qualify your welder, or you may perform 1 root bend test and 1 face bend test. Both methods are acceptable. Some welding process are excepted and welder only can be qualified by bend test and radiography and ultrasonic will not be acceptable. (Like GMAW with Short Circuiting) Acceptance Criteria on ASME Section IX Bend Tset Test requirements for groove welds QW452 consists of either:-One face bend and one root bend except for welding positions 5G & 6G which require 4 bends (Ref QW452.1 Note 4). If the plate exceeds 3/8" side bends may be used. See QW 466 for precise details and exceptions. Note:- Bend Tests can in most cases be replaced by Radiography {See Below}. In cases where bend testing is used to supplement radiography when evaluating welding samples carried out using processes: 131, 135, 138, or 311, two bend test samples must be removed. One sample should be bent with the face outward (face bend test) and the second bent with the root side of the weld outward (root bend test). Welding (8th Edition) Edit edition Solutions for Chapter 25 Problem 27R: How are the specimens bent for a guided-, root-, face-, and side-bend test? … Solutions for problems in chapter 25 1R RE: root cause for failure of bend test stanweld (Materials) 3 Sep 13 09:27 The process is not low hydrogen plus acid based fluxes are often used plus preheating normally not done; hydrogen embrittlement remains a suspect.Root and face bend tests are another simple low cost method of testing. It gives very simple to understand results and will show any signs of poor fusion or weaknesses such as porosity within the weld. There are numerous variations on this method, we will look at one of the most simplest methods. Whether the sample piece is bent root up or root down decides whether it is a root or face bend test, with the root on the outside of the bend, in tension that would be a root bend test. Title of Legally Binding Document: Method of Testing Fusion Welded Joints and Weld Metal in Steel, Part 7: Longitudinal root and face bend test on butt welds Number of Amendments: Equivalence: Superceding: Superceded by: LEGALLY BINDING DOCUMENT Step Out From the Old to the New--Jawaharlal Nehru Invent a new India using knowledge. Under AWS D1.1, our 1" test plates (for unlimited qual) are side bends and the 3/8" test plates are root and face bends. Skimming through some of the test procedures for stainless structural a few weeks back, I believe some of the thicknesses remain constant while the bends ( sides vs. face & root) changed based on the qual (E1, E2, E3...)Face and Root Bends Side Bends LANL Engineering Standards Manual ISD 341-2 Chapter 13, Welding & Joining GWS 1-05, Welder Performance Qualification and Certification, Attachment 9 Rev. 1, 10/27/06 Oct 28, 2019 · Root Bend Test.

Related Videos Feb 16, 2015 · ASME IX table QW-452.1 (a) states that a root & face bend may be substituted for two side bends on mat’l from 3/8” to less than 3/4” (see note 3). If you then go to Figure QW-466.1 you have jig dimensions for mat’l up to 3/8” in thickness. My question is where do you get the jig dimensions for material over 3/8” in thickness? Face bend test- face bend test pieces, when the surface in tension con- tains the largest width of the weld; - root bendtest pieces, when the surface in tension con- tains the root of the weld. When the joint is made from both sides, then the side from which welding commenced first is called the face.Bend one coupon (from each plate) to test the face and one to test the root. 9/14/2011 8 Practical - Retainable - Teachable - Accountable 9. Actuate the ram by the lever on top of machine and stand clear of the guard area where coupon will exit. 10. Inspect the convex surface of the bend specimen for fusion type defects.Sep 23, 2004 · I recently have been trying to qualify a process for .080 Titanium. the spec requires FPI,xray,tensile test then face bend and root bend all in that order. Twice now the samples pass all of the tests until it gets to bend testing. The first attempt failed face bend and the second attempt failed on the root bend. Fusion welded butt joints in steel — Transverse root and face bend test. General information ... Root and face bend tests are another simple low cost method of testing. It gives very simple to understand results and will show any signs of poor fusion or weaknesses such as porosity within the weld. There are numerous variations on this method, we will look at one of the most simplest methods.

The guided bend tests are shown in the figure. Notes: T-Test plate thickness A hardened roll may be utilized on shoulders if needed Specific dimension for 3/7 of the plate Every shown dimension is in inches. 3. Free Bend Test. Root Bend ... The magnetic field is always at right angles to the direction of current flow Guided-bend test To test welded, grooved butt joints on metal that is 3/8 inch thick or less, two specimens are prepared and tested - one face bend and one root bend Nitric acid has the capacity to etch rapidly and should be used on polish services only Hydrochloric acidBend tests may bend the weld towards the face, towards the root, or sideways. The most common is a guided bend test as opposed to a free bend test. Some materials are required by certain codes to be bent at specific radii. The property that dictates this is often the required "elongation" in the specimen.In a root bend test, the test specimen is placed in a jig with the root down, such that the root face is in tension. True. The Vickers test produces a square (pyramid-shaped) indentation. True. The Rockwell hardness test is the most commonly used and versatile hardness 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.ASME IX Destructive Test Specimens Face and Root Bends Side Bends Face and Root Bends Side Bends .

Title: Rev Author: Stone & Webster Created Date:Jul 10, 2014 · Root/Face bends of a coupon thicker than 1/2" will give more stress and more fiber elongation; it was harder to pass this test [and harder on the bending jig]. Additionally, you seem to be getting overly precise. The concept in ASME is to switch to side bends at 3/8" and API to switch at 1/2" [bigger die radius]. - face bend test pieces, when the surface in tension con- tains the largest width of the weld; - root bendtest pieces, when the surface in tension con- tains the root of the weld. When the joint is made from both sides, then the side from which welding commenced first is called the face. angle of 180°. See the following figures for acceptable and unacceptable bend tests. Tampering with the test specimens, such as by rewelding to hide visible discontinuities, either before or after bending will result in the immediate loss of bend testing privileges and failure of the welders.
