A battery component for use in a flow battery is provided with a weld rib pattern on a planar surface thereof. The weld rib pattern includes respective weld ribs defining a sealable flow region therebetween and further includes respective flash traps disposed adjacent each of the weld ribs opposite the sealable flow region. The battery components are stacked one on top of the other and friction welded together to form a flow path within the sealable flow path region. During the welding process, the weld rib material is melted and deposited in the adjacent flash traps.
