Welder Qualification Test - Eiwaa Group

     This article talks about the Welder Qualification Test  based on requirements of ASME Code Section IX. The WPQ record indicates the ability of the welder or welding operator to deposit sound weld metal.


Each manufacturer or contractor shall maintain a record of the result obtained in welding procedure and welder/operator performance qualifications. As minimum any welding performance qualification record should indicate the essential variables, the range of qualified variables such as material, pipe diameter, thickness, position etc. The record also should indicate the result of mechanical or nondestructive testing result.



The Welder Qualification Test can be qualified by either radiography or ultrasonic testing; alternatively it can also be qualified by mechanical testing. The required number of testing is different from PQR and is less stringent. The Welder Qualification Test can be qualified by one face bent test and one root bend test. The bend test actually checks the ductility of the weld metal which is important factor in the depositing sound weld metal.


I have seen folks confusing between WPS and Welder Qualification Test requirements like the position which normally is not essential variable in WPS but it is essential variable in the WPQ. The other confusion happens in the qualified thickness range, backing and pipe diameter etc.


Welder Performance Qualification


This document is required by all codes for all welders. It details and summarizes the following information: Indicates the WPS referenced during the qualification test Identifies the welder by name and/or clock number Lists what the essential parameters were during this test Reports the results of the required qualification tests Specifies qualified limits for welder For most codes there is a time limit associated with the welder qualification test.


However, the American Welding Society provides an unlimited qualification period if certain conditions are met. As with the WPS and WPQR, each code has a recommended format.

Are you looking for Eddy Current Testing - Eiwaa Group

Image
Eiwaa Group of  Eddy Current Testing system was specially developed for quality testing and process monitoring of long products. From hot testing to all bright steel processing steps, the surfaces of semi-finished products made from austenitic, (non) ferromagnetic metals can be tested for defects. The system operates in a contactless and non-destructive manner in accordance with the Eddy Current Testing method and is used for detecting short defects, such as holes or localized defects and transverse defects.  The systems detect defective materials fully automatically and reliably. Defects can be marked, classified, and automatically discarded. The test speed of up to 150 m/s facilitates 100% testing, even at high production speeds. The systems benefit from low operating costs and frugal energy consumption as well as low maintenance costs, few wear parts, and low use of materials. Eddy Current Testing :  It is based on the principle of generating circular electric curre...

Best Eddy Current Testing in Saudi and UAE - Eiwaa Group

Image
Eddy Current Inspection is one of several NDT methods using the principle of electromagnetism to conduct examinations. Other methods, such as remote field testing (RFT), flux leakage also use this principle. Eddy Current Testing is completed through a process called electromagnetic induction. When alternating current is applied to the conductor, such as copper wire, a magnetic field develops in and around the conductor. This magnetic field expands as the alternating current rises to maximum and then collapses as the current is reduced to zero. When another electrical conductor is positioned in close proximity with this changing magnetic field, current will be induced into this second conductor. Eddy currents are induced electrical currents that flow in a circular path. Current testing takes its name from Eddies, which are formed when a liquid or gas flows in a circular path around obstacles under the right conditions. ID probes, also referred to as Bobbin probes or feed-through pr...
