What is the maximum depth of undercut permitted in transverse splices of primary members?

The maximum depth of undercut permitted in transverse splices of primary members is indeed 0.01 inches. This specification is crucial in maintaining structural integrity and performance. Undercuts can significantly affect the strength of a weld by creating stress concentrators that can lead to further degradation of the material if not controlled.

Having a strict limitation on undercut depth helps in ensuring that the welds provide the necessary strength without being compromised by local weaknesses. A depth greater than this specified limit can lead to potential failure points in the weld, especially in critical load-bearing applications.

While undercuts of 0.02 inches, 0.015 inches, or 0.005 inches may seem acceptable to some, they do not align with the typical industry standards set for primary members in construction. Maintaining adherence to the 0.01-inch limit is essential for compliance with welding codes and standards, ensuring that the structural components perform safely under design loads.
