Weld category
Weld category classifies welded joints according to safety significance and loading. Higher categories require stringent testing and qualifications.
Physical-Chemical Mechanism of Action
The weld category refers to the mechanical safety and service life of welded joints. The higher the category, the more critical the application and the more important precise processes and high-quality materials become.
Metallurgical Relevance & Welding Risks
Weld categories help in selecting the right process and material. Wrong categories can lead to safety issues, such as cracks or failure under load. It is crucial to choose the correct category for the specific application.
Shop Practice & Action Items
In the shop, the weld category is determined by load and safety significance. For higher categories (e.g., Category 3), special inspection procedures and qualifications must be followed. Always use the appropriate material and perform precise welding processes to ensure the required safety.
