You need to have a copy of Section IX and understand it. The world of product development, manufacturing, and production is changing. First, prepare a welding procedure specification WPS. Similarly, when the code requires notch-toughness, supplementary essential variables become additional essential variables.

Welders and Welding Operators may be qualified by visual and mechanical tests, or by radiography of a test coupon, or by radiography of the initial production weld. Each process is listed separately in QW with the essential, supplementary essential, and nonessential variables. Actual variables Essential variables Tests and results.
This secrion is not going to do that for you. The WPS shall specify a value or range for each essential, nonessential and, when necessary, each supplementary essential variable listed for each welding process.
Weld repair qualification of ASME BPVC Section IX - ASME (mechanical) Code Issues - Eng-Tips
The WPS provides guidance for sectoon by specifying ranges for each variable. The world of manufacturing is rapidly advancing and key to that evolution is the development of technologies related to product design and quality control. Register now while it's still free! Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden. First, prepare a welding procedure specification WPS.
The Eng-Tips staff will check this out and take appropriate action. Promoting, selling, recruiting, coursework and thesis posting is scetion. Understanding this document may make procedure qualification easier for casting.
The goal is to repair welding on casting during casting processes. James, Agree with metengr.
Join your sectino on the Internet's largest technical engineering professional community. Though the requirements are heavily based on ASME Sec-IX, the repair kx and qualification regime for casting repair could be slightly different. When a change is made in a supplementary essential variable, the WPS must be revised, and requalified by a new PQR, unless the revision can be supported by an existing PQR for notch-toughness applications.

Resources The world of product development, manufacturing, and production is changing. Thanks Juergen, deposited weld metal thickness: Same applies for welders also. Close this window and log in. There are tables for welding positions signifying that a welder who qualifies in a particular position is qualified to weld within a range of positions as appropriate.
Some of the welding variables are listed below: It's easy to join and it's free. May we adopt 38mm of groove weld for all qualification of QW Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Are you an Engineering professional? The WPS is qualified by welding procedure qualification test coupons. The PQR shall record the value for each essential and, when necessary, each supplementary essential variable used.
We are a casting supplier of manufacturing austenitic stainless and carbon steel. Third, the performance of the welders is verified by welding performance qualification test coupons.
You need to have a copy of Section IX and understand it. If a customer discovers a repair in a purchased casting he is going to want to know the full history of that repair and if you can't supply the correct documentation you could end up in a court of sectjon. Another way of conceptualizing these requirements is shown below:
