For any pressure vessel or boiler construction, a Welding Procedure Specification (WPS) must be developed. ASME Section II Part C is critical during this phase:

The section is organized by material types and welding processes, such as shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and submerged arc welding (SAW). Importance in Engineering and Fabrication

Standardized specifications provide a clear trail for quality assurance and third-party inspections. Accessing the ASME Section II Part C PDF

ASME Section II Part C does not create these specifications from scratch; instead, it adopts many standards from the American Welding Society (AWS).

is the designated "Service Section" within the ASME Boiler and Pressure Vessel Code (BPVC) that contains the essential specifications for welding rods, electrodes, and filler metals. It serves as a mandatory technical reference for engineers, manufacturers, and inspectors to ensure that welding consumables used in pressure-retaining components meet strict safety and quality standards. Core Purpose and Scope

Using a consumable not listed in Part C often means the weld is not code-compliant.
