What is required for welding activities according to the ITP?

A Welding Procedure Specification (WPS) is fundamental to welding activities as it outlines the specific requirements for the welding process being employed. It serves as a critical document that details essential variables such as the materials to be used, the welding technique, and the parameters for heat input, among others. The WPS is designed to ensure that the welding work meets the required standards and specifications, which is crucial for the integrity and safety of the final product.

Having a WPS helps to standardize the welding practices across various projects, ensuring consistency and quality control. It lays the foundation for welder qualification and ensures that personnel are following the established procedures, which in turn minimizes the likelihood of defects and issues in the welded components.
