What Are AWS Structural Welding Codes?

AWS Structural Welding Codes are a series of rulebooks published by the American Welding Society (AWS). They provide the standards, requirements, and guidelines for welding different types of metal structures safely and correctly.

Think of them as the official “how-to” manuals for welding everything from steel buildings and aluminum bridges to stainless steel tanks and sheet metal parts.

Why Are They Important?

These codes:

• Ensure safety in structures like buildings, bridges, and pipelines

• Standardize welding practices across industries

• Guide engineers, inspectors, and welders in performing and checking welds

• Help prevent weld failures, which could lead to accidents or structural collapse

What Do They Include?

Each code usually includes sections on:

• Design requirements (how the welds should be planned)

• Welding procedure specifications (WPS)

• Welder and welding operator qualifications

• Inspection and testing methods

• Acceptance criteria (what makes a weld pass or fail)
