What is the maximum allowed length of a crack or fracture that can be welded?

The maximum allowed length of a crack or fracture that can be welded is 200mm (8 in). This guideline is essential in ensuring the structural integrity and safety of a container after repairs. Welding a crack or fracture exceeding this length could compromise the strength of the container, potentially leading to failure during use.

In practical terms, maintaining a limit on the length of a weldable crack helps inspectors and repair personnel to identify whether a repair is feasible without risking the container's safety. A crack longer than this would typically require more extensive repair techniques, possibly including complete panel replacements or reinforcement, rather than simply weld repairs. The established standards, therefore, emphasize the importance of adhering to these specifications to ensure the reliability and durability of containers in service.
