Focuses on the materials used to join metals. It ensures that the weld metal matches or exceeds the properties of the base materials being connected.
Use Part C to pick the correct welding wire or electrode to ensure the joints are as strong as the shell.
Without Section II, engineers would lack a uniform language to verify that the steel, alloys, or non-ferrous metals used in boilers and pressure vessels can withstand extreme temperatures and corrosive environments. The Four Parts of Section II asme boiler and pressure vessel code section ii
For a shop with an ASME "S" or "U" stamp, your QC Manager should treat Section II like a law book. It dictates:
The ASME Boiler and Pressure Vessel Code Section II is the definitive global standard for the selection and specification of materials used in the construction of pressure equipment. While other sections of the Code focus on design rules or fabrication methods, Section II provides the "ingredients list"—the strict chemical, physical, and mechanical requirements that materials must meet to ensure safety and structural integrity under pressure. Focuses on the materials used to join metals
Most ASME Section II specifications are identical to, or heavily based on, ASTM (American Society for Testing and Materials) standards. When ASME adopts an ASTM standard for pressure vessel use, it is prefixed with an "S" (e.g., ASTM A106 becomes ASME SA-106).

If you are specifying steel for a heat exchanger, ordering plates for a steam drum, or qualifying a new alloy for cryogenic service, Part II is your definitive guide.

This part ensures that the joining processes (welding and brazing) meet the same rigorous standards as the base metals.
