Weld support comprising ceramic strips held together by metal strip, has areas of weakness in metal strip close to joints between ceramic strips

摘要

The metal strip (6) contains areas of weakness (11, 11) at regular intervals to make the strip easier to break. These areas of weakness are located close to the joints (12, 12) between adjoining ceramic strips (5-5). Flat strips of ceramic material are joined end to end and held together by a metal strip with a base and raised side walls.
