NIAC can help you with any Welding Procedure Specification (WPS) development. There are three different development stages, which you can choose from depending on the essential variables such as welding process, filler metal, base metal, shielding gas, welding position, joint geometry, etc.
Option 1: is Pre-Qualified. AWS offers quite an array of Pre-Qualified welding procedures. The processes it covers are SMAW, GMAW, FCAW and SAW. The exception to Pre-Qualified AWS processes are GMAW-S & GTAW (except in Stainless Steel). These are not recognized pre-qualified processes by AWS.
Option 2: if working with structural steel or pressure vessels, AWS offers a small array of SWPS's (Standard Welding Procedure Specifications). These can be purchased from AWS. But please note, purchasing an SWPS from AWS will not provide you with a PQR (Procedure Qualification Record) , this can sometimes become a problem with engineers and customers. It is best to check with your customer before purchasing and utilizing SWPS's.
Option 3: Is used when it is unfeasible to utilize pre-qualified WPS's and SWPS's, and involves developing a procedure from scratch. This can become quite complicated and costly if data is not collected and executed correctly. The first step NIAC takes is helping you pick out what welder in your facility will weld up the PQR test. We like to take our time, educate your staff and welder on the expectations this test holds. PQR (Procedure Qualification Record) is the supporting document that details elements of a process, essential variables or method used to produce a specific result. Basically we find all the parameters we need to meet in this Welding Procedure Specification, then we mock up a joint or in some case just a test coupon, as the welder is welding the coupon up, we record all data essential to the PQR. The data and weld coupon or joint will be sent to a metallurgical lab, and depending upon the process and application, there is a gamut of tests, destructive and non-destructive, administered on the joint or coupon. We receive the test results back from the lab, check and see if the values are code compliant for this particular process, and from there we develop the Welding Procedure Specification., with the PQR and lab reports attached.
