Name two major welding codes or standards that may apply alongside or within AWS guidelines.

• A. AWS D1.1 (Structural) and ASME BPVC (Boiler & Pressure Vessel Code).
• B. ISO 9001 and ISO 14001.
• C. EN 1090 and DIN.
• D. AWS D9 and AWS D4.

Answer: (A)

Welding projects often rely on specialized codes tailored to the application, in addition to AWS guidelines. The two major codes you’ll encounter are the structural welding code for steel structures and the code for boilers and pressure vessels. The structural code sets detailed requirements for weld design, welding procedures, material suitability, preheat and interpass temperatures, post-weld heat treatment when needed, and nondestructive testing methods specifically for structural steel in buildings, bridges, and similar assemblies. The boiler and pressure vessel code governs weld quality and safety for vessels and piping that contain or transmit pressurized fluids, covering its own requirements for weld procedures, welder qualification, heat treatment, and inspection to ensure safe operation. In practice, a project may call for AWS guidelines as the baseline, while also requiring adherence to these codes depending on the component—structural work follows the structural code, while pressure-containing equipment follows the boiler and pressure vessel code. Other standards you might see in different contexts address quality systems or European structural requirements, but they are not the same kind of welding codes, so the combination of AWS with AWS D1.1 and ASME BPVC covers the common, application-specific welding standards you’d expect to encounter.
