Which section of the ASME codes deals with welding?

Section IX of the ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code specifically addresses the qualifications for welding and brazing procedures and personnel. It provides guidelines for the qualification of welders and welding procedures to ensure that they meet industry standards for safety, quality, and reliability.

This section outlines the necessary tests and documentation required to ensure that welders have the appropriate skills and that welding procedures are effective and produce strong, durable welds. It sets forth requirements for different materials, types of welding processes, and the conditions under which welding must be performed. By establishing these standards, Section IX plays a crucial role in maintaining the integrity of welded structures in various applications, from pressure vessels to piping systems.

The other sections of the ASME codes focus on different aspects of boiler and pressure vessel design, construction, and operation. For instance, Section I pertains to the rules for making safe design and construction of power boilers, Section IV focuses on heating boilers, and Section VII addresses the recommended guidelines for the care and maintenance of boilers. While these sections contribute to the overall safety and functionality of pressure equipment, it is Section IX that specifically concentrates on welding qualifications.
