Welding material standards are an important basis for ensuring welding quality and safety. Different countries or regions have formulated corresponding standards according to their own industrial needs. The following are several common welding material standards and their characteristics:
1. ISO (International Organization for Standardization Standards)
ISO standards are internationally accepted welding specifications, covering material classification, process requirements and quality inspection, aiming to coordinate national standards and promote international trade. ISO 2560, ISO 14341 and other standards correspond to the technical requirements of welding rods and welding wires respectively. The characteristics of ISO standards are strong versatility and are applicable to the global market, but they may need to be used in combination with local standards.
2. AWS (American Welding Society Standards)
AWS standards are formulated by the American Welding Society and are widely used in North America. It covers welding materials, processes, equipment and personnel qualifications. The AWS A5 series is the main standard for welding materials, such as AWS A5.1 for carbon steel electrodes and AWS A5.18 for low-alloy steel wires. AWS standards are known for their practicality and flexibility, focusing on actual welding performance.
3. GOST (Russian State Standards)
GOST is the national standard of the former Soviet Union and Russia, and is still widely used in Central Asia and Eastern Europe. GOST standards have strict requirements on the chemical composition, mechanical properties and process properties of welding materials. For example, GOST 9467 is used for welding rods and GOST 2246 is used for welding wires. The characteristics of GOST standards are strong systematization, but slow updates.
4. EN (European Standard) Standards:
Features: EN standards are formulated by the European Committee for Standardization (CEN) and are enforced in European countries. Some standards are equivalent to ISO standards. Some EN welding standards are directly converted from ISO standards (such as EN ISO XXXXX format) and are compatible with the international standard system.
5. DIN (German Institute for Standardization Standards)
DIN standards are formulated by Germany and have an important influence in Europe, especially in the German-speaking region. The DIN EN ISO series combines ISO international standards for welding materials, processes and quality control. For example, DIN EN ISO 2560 is used for carbon steel welding rods and DIN EN ISO 14341 is used for welding wires. DIN standards are known for their rigor and high quality, with attention to detail and operability.
6. JIS (Japanese Industrial Standards)
JIS standards are formulated by Japan and are widely used in Asia. The JIS standard has very detailed requirements for the classification and performance of welding materials, such as JIS Z 3211 for low-carbon steel electrodes and JIS Z 3312 for welding wires. The characteristics of the JIS standard are advanced technology, environmental protection and efficient production.
7. GB/T (China National Standard)
GB/T is a Chinese national standard formulated by the National Standards Committee. GB/T 5117 is used for carbon steel electrodes and GB/T 8110 is used for welding wires. The GB/T standard combines international standards with China’s actual domestic needs, focusing on practicality and economy, and has gradually been in line with international standards in recent years.
In summary, welding material standards in different countries and regions have their own characteristics, but the overall goal is the same, that is, to ensure the quality of welding materials and welding process specifications. Choosing the right standard requires considering factors such as specific application scenarios, product requirements and target markets.
