Prequalification of WPSs – Provides the requirements that need to be met in order to be exempt from having to perform testing to qualify welding procedures.

Understanding how to calculate the allowable strength for a given weld will allow you to design weldments and provide this information for the shop, rather than expect the shop to make engineering decisions such as the proper size of a weld. Need information on calculating allowable stresses? It’s all in this clause. It includes information for designing structures for both static and cyclic loading. This clause contains a wealth of engineering information that can help you design weldments properly and avoid costly overwelding. Design of Welded Connections – Spells out requirements for the design of tubular and non-tubular structures for both static and cyclic loading.Also provides definitions for terms used throughout the code. General Requirements – Provides the scope of the code including material thickness and strength ranges of structural carbon and low alloy steels.Below we provide a brief description of each of the 9 clauses. Welding codes contain much more than that.īefore you can take advantage of the AWS D1.1 you need to understand what it includes. As stated above, most of us only think of the welding codes only as instructions for qualifying welders and welding procedures and acceptance criteria for the inspection of welds. D1.1 can be used as a basis for developing your own quality standards. If you ever have a chance to attend a D1.1 code clinic we encourage you to do so.

Or, at the very least, you’ll be able to speed up the learning curve. However, with proper instruction you can avoid costly mistakes that are inevitable when you go it alone. It is definitely possible to pick up the code and teach yourself how to use prequalified welding procedures and how to qualify welding procedures by testing. Yet, it is extremely hard to follow if you have never been given proper instruction on how to do so. This code provides way more detail that you ever thought was available when it comes to making welds on structural components.
