Another Damn Weld Dam?

If you notice on the right side of the beam, there is a hold back for the weld termination point. This is most likely to prevent the development of a stress riser, if the weld were to terminate at the corner. For what ever reason, the engineer needs the welds to travel the full length of the stiffener on the left side. To prevent the development of a stress riser on the left side, the engineer has designed a plate for the weld to tie into. My question would be, how wide is that termination plate suppose to be.

Dams, in the sense used by D1.X welding codes, are blocks of metal placed at the ends of the groove to prevent the liquid weld pool from spilling out of the groove. Slag inclusions can be found at the ends of the weld beads in the completed groove weld when dams are used.

Extension tabs or run-off tabs are the preferred method of extending the groove to ensure sound weld at the ends of the groove weld.
