ABSTRACT:
The tendency of molten weld metal to burn through a supported refractory welding backup material is greatly reduced by incorporating a woven carbon fiber cloth between the refractory and the support. A preferred product is a pressure-sensitive adhesive tape construction incorporating the carbon-fiber cloth in the backing; surprisingly, the carbon does not embrittle the weld.
