Commonly Used Welding Codes
Introduction
Welding codes are a set of standards and guidelines that are used to ensure quality and safety in welding. They define the requirements for welding procedures, materials, testing, and inspection. Welding codes are developed and maintained by various organizations such as the American Welding Society (AWS), International Organization for Standardization (ISO), and others. In this article, we will discuss some commonly used welding codes.
American Welding Society (AWS) Codes
The AWS codes are widely used in North America and are recognized by many countries around the world. The most commonly used AWS codes are:
- AWS D1.1: Structural Welding Code – Steel
- AWS D1.2: Structural Welding Code – Aluminum
- AWS D1.3: Structural Welding Code – Sheet Steel
- AWS D1.6: Structural Welding Code – Stainless Steel
- AWS D14.1: Specification for Welding of Industrial and Mill Cranes and Other Material Handling Equipment
International Organization for Standardization (ISO) Codes
The ISO codes are developed by the International Organization for Standardization and are used worldwide. The most commonly used ISO codes are:
- ISO 9606-1: Qualification testing of welders – Fusion welding – Part 1: Steels
- ISO 5817: Welding – Fusion-welded joints in steel, nickel, titanium and their alloys (beam welding excluded) – Quality levels for imperfections
- ISO 15614-1: Specification and qualification of welding procedures for metallic materials – Welding procedure test – Part 1: Arc and gas welding of steels and arc welding of nickel and nickel alloys
American Society of Mechanical Engineers (ASME) Codes
The ASME codes are used in the United States and are recognized worldwide. The most commonly used ASME codes are:
- ASME Section IX: Welding and Brazing Qualifications
- ASME B31.1: Power Piping
- ASME B31.3: Process Piping
- ASME B16.5: Pipe Flanges and Flanged Fittings
- ASME Boiler and Pressure Vessel Code: Rules for construction of boilers and pressure vessels
Conclusion
Welding codes are an essential part of the welding industry. They ensure quality and safety in welding and provide a set of standards and guidelines for welding procedures, materials, testing, and inspection. By following these codes, welders can produce high-quality welds that meet industry standards and customer expectations.
