Abstract
An undeformed weldable insert is inserted into an undercut recess opening at an inner face of an abrasion resistant ceramic brick and thereafter deformed into the undercut and interlocked with the brick. The insert is then welded to a substrate either by inserting a welding rod through a small guide hole into the recess from the abrasion resisting outer surface of the brick and then into guided welding contact with the substrate through a hole in the insert, or by inserting the welding rod through a hole in the substrate opposite the insert. Alternatively the inner face of the brick is overlaid with a fluid hardenable plastic that fills and interlocks with the undercut recess to provide means for bolting or cementing the brick to a substrate to be protected.
