There is a significant cost to obtain the new edition – $480 ($640 for non-AWS members). But before you start thinking that this is AWS’s way of making money you must know that frequent update of codes and standards are mandated by the American National Standards Institute (ANSI). Revisions are necessary to address issues that were not addressed by a previous version but which are important to users.

The question we always get when a new edition comes out is if it is necessary to buy the new edition. The answer is yes. Any code work, whether welding procedure prequalification or qualification, welding inspection, weld design, etc. must be done using the current code. However, any WPSs or other work that was done or started with the previous code is still governed by it. You do not need to update anything done prior to this year.

Also, if you are not able to get your hands on the new AWS D1.1 for a while and you are concerned about developing and testing new welding procedures you must not worry. The only significant change is in regards to using welding equipment with waveform technology. And this applies only to the calculation of heat input. We will discuss this further on next week’s article.

Newer welding equipment technology allows for the calculation of the amount of energy going into a weld.

All tests for procedure qualification as well as welder performance qualification remain the same. Your WPS, PQR and WPQR forms will only change when making reference to tables, figures or sections of AWS D1.1. The new version has 11 clauses instead of 9. Clause 3 (Prequalification) is now Clause 5. Clause 4 (Qualification) is now Clause 6. And Clause 9 (Tubular Structures) is now Clause 10. These are the three clauses that apply to prequalification and qualification of welding procedures and welders.

Additions of tables and figures as well as change in their order within clauses mean that changes to their reference numbers are not as simple as going from, for example, Table 3.1 to Table 5.1. So if you do not yet have the new copy do not attempt to change your references.
