Webjoints can serve as a stress concentrator and crack initiator. To eliminate this condition, for the bottom beam flange to col-umn flange connection, the steel backing is removed and the root pass is gouged to sound weld metal. The welder must then re-weld the gouge and add a contouring fillet weld under the bottom flange.
