To some, WPSs are a necessary evil, a paperwork requirement that is required by codes like AWS D1.1. To others, a WPS is used by welding inspectors to ensure welding is performed within acceptable limits and is often used to shut down welding operations. Others may see WPSs as the method by which Engineers confirm that the means and methods of the Fabricator or Erector meet specification requirements. Finally, some Fabricators or Erectors see WPSs as an issue that needs to be addressed in order to pass an AISC audit. The authors will show that WPSs are critical tools for each group to control quality and productivity. When the primary purpose is understood, the focus of WPS development and enforcement changes. Practical examples of correctly and incorrectly prepared WPSs will be given to demonstrate the importance of proper WPSs.
