» CBT is used to prevent molten metal leakage from the backside of a full penetration weld. A full penetration weld requires something to block the gap from molten metal overflow. CBT helps achieve that.
» Ceramic Backing tape is a non-metallic ceramic material which is temporarily attached to the reverse side of a weld while helping to support a full penetration weld.
» It is made with several pieces of small ceramic tiles, glued to an adhesive tape.
» It is easy to apply, easy to clean up after the welding is completed, and can greatly improve welding quality and throughput.
