The Why and How of Welding Procedure Specifications - Both
Welding Procedure Specifications - Ensuring Consistent, Predictable Welding Processes Performance
As a welding professional, if you are constantly responding to customer demands for increasing the performance and quality of weldments while controlling costs, optimizing your WELDING PROCEDURE SPECIFICATIONS (WPSs) for performance and profitability may be the key. A well written WPS Defines, Measures, Analyzes, Improves, & Controls (DMAIC) quality in the welding process. This 2-part workshop revisits the fundamentals of WPSs for both the seasoned professional and for those individuals seeking to become more proficient in the authoring and application of a WPS in fabrication as well as a hands-on approach to advanced instruction in the formulation and writing of WPSs in the afternoon.
Who Should Attend
This session will benefit owners, managers, engineers, and CWIs who must qualify, write, or revise welding procedure specifications to satisfy codes and contract documents.
What Will Be Addressed?
This workshop is divided into two half-day sessions. The morning session addresses the fundamentals of WPSs. Morning topics are focused on:
- Standard terminology
- Welding processes
- Filler metal
- Shielding gases
- Current and voltage range, travel speed and heat input
- Joint design tolerances
- Joint and surface preparation
- Preheat / interpass temperature
- Welding positions
- Standard WPSs
The afternoon session focuses on the mechanics of WPSs by different codes and standards. Afternoon topics include:
- Proper preparation and qualification of welding procedure specifications
- Documenting standard procedure qualification testing for commonly used processes for joining ferrous plate and pipe
- Selecting and documenting welding variables
- Specifying essential and nonessential variables commonly used in sample AWS, ASME, and API code formats
- Different techniques to author WPSs
