Which type of weld requires continuous inspection according to the International Building Code?

The International Building Code specifies that continuous inspection is required for certain types of welds based on their size and application. Specifically, single-pass fillet welds that exceed 5/16 inch in size require continuous inspection to ensure the integrity and quality of the weld.

This requirement arises from the fact that larger welds can be more critical in terms of structural performance and might have implications for the overall stability and safety of the structure. By requiring continuous inspection, the code helps ensure that any potential defects, such as inadequate fusion or improper penetration, are caught and addressed promptly during the welding process.

Other weld types or sizes might not necessitate this level of ongoing scrutiny, as smaller welds or multi-pass welds may have established practices in place to monitor their quality. This illustrates the code’s focus on balancing the need for thoroughness in inspection with practicality, reflecting a clear understanding of the critical aspects that contribute to structural integrity in construction.
