toe grinding
(OP)
hey folks,
Couldn't find anything on the subject here, so here goes...
I've always heard that when you are having difficulty getting a weldment to work due to fatigue (i.e. endurance limit is reached too early), toe grinding can be employed which improves the fatigue performance of the particular weldment. I am wondering what the mechanism is behind the additional endurance that the weld gets when it has been treated in this fashion? Is it a matter of internal stress relief from the grinding procedure? If so, i would think a post heat treatment would have a similar effect??
thanks

The concept is that there are inherent oxides, slag, and small cracks along the toes of the fillet weld. Remelting the area of the fillet weld toe and adjacent base metal, using GTAW, eliminates many of the small cracks, oxides, and slag.
