Apparatus for welding with granular material on a rotating cylindrical surface having a welding tool and a flux fence for holding said material on said surface until such said material has passed a predetermined point, the improvement in said fence comprising: a support member; a shaft fixed to said support member; a plurality of wheels loosely journaled on said shaft in such manner to allow independent vertical movement of each of said wheels relative to any other wheel; and a pair of peripherally extending members loosely journaled on said shaft external to said wheels on opposite ends of said shaft and adapted to engage said cylindrical surface, whereby any of said wheels and said peripherally extending members can ride over an irregularity of said cylindrical surface without causing like members to do so.
