Abstract
A weldable abrasion resistant ceramic brick is formed with spaced recesses extending angularly into the brick to undercut a surface thereof and interlock with a weldable insert having angularly extending projections mating with and insertable into the recesses. Each recess may be defined by a wall inclined into the undercut for camming an aligned projection into the undercut. The insert and brick may be interlocked and thereafter welded to a substrate, or the insert may first be welded to the substrate and thereafter interlocked with the brick. The invention is particularly useful with comparatively thin abrasion resistant wear plates that heretofore could not be welded satisfactorily to a substrate.
