ASME Section IX Code is set of rules, guidelines, and requirements for Welding, Brazing, and Fusing Qualifications. It is a reference code that helps for BPVC Construction Codes for Qualifications of Welder or Welding Operator, Brazer or Brazing Operator, and Fuser or Fusing Operator.
Now, we see the rules, guidelines and requirement s for welding and welder qualification as per ASME Section IX, out of above-listed subsections Part QG and Part QW are only related to welding qualification process. So that we will discuss Part QG and Part QW in Details.
In this part consist of all the general requirement that are required to follow for Welding, Brazing, and Fusing Qualification. Those requirements which are particularly applicable to only one process that is explained in their individual general requirement article. Part QG consist of the following subsections:
This Article covers Welding General Requirements for Welding Procedure Specification (WPS), Performance Qualification Records (PQR) and Welding Performance Qualification (WPQ) under the scope of ASME Section IX.
This Section Listed All Essential Variables, Non-Essential Variables, and Supplementary Variables Each Welding Process Separately. This Article helps to Specify a range of Essential Variables, Non-Essential Variables, and Supplementary Variables while preparation of WPS. As per ASME Section IX WPS form is used to specify ranges of these all variables and PQR form is used to record the value of each Essential Variables, Non-Essential Variables, and Supplementary Variables.
This Article provides list of Essential variables for Welding Performance qualifications. WPQ forms must record a value for each essential variable used and must list a range qualified for each of these essential variables. This Article covers responsibility, type of tests, records, welder identification, positions for Welder Performance Qualifications. Welder and Welding Operator can qualified by interpreting and recording results of Destructive and Non-destructive Tests.
This Article also covers P-Number, F-Number and A-Number for Joining Materials and Welding Materials. This Article covers Maximum Qualification Limits of Thickness and Diameters for Welding Procedure and Performance Qualifications and also includes Qualification Positions for Welding and Welder Performance Qualifications.
