What is the importance of following welding procedure specifications (WPS)?

Following welding procedure specifications (WPS) is essential because it serves as a documented guideline that outlines the parameters and methods to be used in the welding process. This ensures that the welding is performed consistently and adheres to both safety standards and structural integrity requirements. By following the WPS, welders can achieve predictable results, minimize defects, and maintain high-quality standards in their work.

WPS is also crucial for meeting regulatory and industry-specific codes, which may dictate how welds must be performed to ensure the safety and reliability of welded structures. Consistency in welding practices reduces variability, which can lead to stronger joints and less chance of failure in service.
