These are most easily NDT tested in both tubular

Clad Thickness Measurement System - NDT.net

The clad thickness system previously developed was tested on a block provided by EPRI, test block 104-1D1, shown in Figure 10. This block is clad with stainless steel except in a 4.5 x 4.5 in attachment weld region that is covered with Inconel (Alloy 182). Tests were performed in both the stainless clad and the attachment weld regions.Determination of the Mechanical Properties of Friction stainless welded with thin wall thickness with et ut testThe welding parameters used are as follows friction pressure rate of 15 MPa per second, forging pressure rate of 37 MPa per second, and rotational speed of 900 rpm. The upset distance is approximately two times of the wall thickness. 40 samples were welded with the above-mentioned process parameters under the same conditions.Guidelines for Automated Ultrasonic Inspection Austenitic stainless welded with thin wall thickness with et ut testApplication Notes

Manual ultrasonic inspection of thin metal welds

Phased array technology for weld inspection is becoming mature, with a draft standard for weld inspection BS EN 13588(6), and this standard and technique were also adopted. 2. Test Samples The test samples specified consisted of plates 3, 4 and 5mm thick in ferritic and stainless steel, each containing 4 flaws.Non-Destructive Testing UK Leading Weld Testing NDTVisual inspection is a popular weld quality inspection method and is one of the most common Non-Destructive Testing (NDT) methods. It involves a visual testing of welds and is capable of detecting surface-breaking defects, as many welding flaws are on the surface and can easily be detected via this Welding Procedure and Welder Qualification Testing procedure.Questions & Answers - Thickness Gauging Level 2Questions & Answers - Thickness Gauging Level 2 by Rolf Diederichs * Acknowledgement Before we made this Q&A we read the articles from Focus on Thickness Measurement in UTonline 10 97 So you may do this also before you start or after you have failed :-)

Radiographic and Ultrasonic Testing of Welds

This testing method is usually suited to having access to both sides of the welded joint (with the exception of double wall signal image techniques used on some pipe work). Although this is a slow and expensive method of nondestructive testing, it is a positive method for detecting porosity, inclusions, cracks, and voids in the interior of welds.Rules for Classification and Construction II Materials and stainless welded with thin wall thickness with et ut testinspection of drawings or a welding procedure test). 1.3 A weld shape appropriate to, and adequately dimensioned or well designed for the nature (static or dynamic) and magnitude of the forces to be transmit-ted shall be chosen. Where necessary, documentary proof Seamless or welded pipes? - BUTTINGtolerance for wall thicknesses of welded pipes is defined in ASTM A999 or EN ISO 1127 T3. The evenness of the steel plate or coil thickness ensures that the wall thickness tolerance remains constant across the entire pipe body and much better than the required

Since the sound beam essentially propagates in fine-grain base material, shear waves can reliably detect flaws at the near-side of the weld.Tube Inspection - Eddy CurrentThe operating frequency is determined by the tube material and wall thickness, ranging from a few kHz for thick-walled copper tube, up to around 600 kHz for thin-walled titanium. Tubes up to around 50 mm diameter are commonly inspected with this technique.
