6.3.1
Projecting elements of connection materials need not be straightened in the connecting plane, subject to the limitations in ANSI/AISC 360.
6.3.2
Backing and runoff tabs shall be used in accordance with AWS D1.1/D1.1M as required to produce sound welds. The fabricator or erector need not remove backing or runoff tabs unless such removal is specified in the contract documents. When the removal of backing is specified in the contract documents, such removal shall meet the requirements in AWS D1.1/D1.1M. When the removal of runoff tabs is specified in the contract documents, hand flame-cutting close to the edge of the finished member with no further finishing is permitted, unless other finishing is specified in the contract documents.
Commentary
In most cases, the treatment of backing and runoff tabs is left to the discretion of the ODRD. In some cases, treatment beyond the basic cases described in this section may be required. As one example, special treatment is required for backing and runoff tabs in beam-to-column moment connections when the requirements in ANSI/AISC 341 must be met. In all cases, the ODRD should specify the required treatments in the contract documents.
6.3.3
Unless otherwise noted in the fabrication documents, high-strength bolts for shop-attached connection material shall be installed in the shop in accordance with the requirements in ANSI/AISC 360.
