Ceramics are a good insulator, though. I have heard of guys making firebrick tables, small furnaces from piled up firebrick, or piles of firebrick to warm large castings. A better-phrased question might get a more informed answer.

Root pass backup. Posted by TinLizziedl on July 21, 2009, 4:35 am Please log in for more thread options Use of ceramics as a backing material is widely accepted. Most commercially available ones I've seen come with a sticky-sided steel tape pre-attached. Simply peel and stick the ceramic against the back side of the work (far side of the root pass from where you are welding) and fill in the gap. That said, it does take some skill to end up with a U.T. or R.T. passable weldment. In my place of employment, you can only use it if the engineers say you can (backside only accessable enough to remove the ceramic, but not enough to backgouge and weld). Typically it is only used in flat, horizontal, and vertical welds. -- Tin Lizzie "Elephant: A mouse built to government specifications."-Lazarus Long Similar Threads Posted rich welder - sell Welding Equipment & Machines & mask,Power Tools,Motorcycle & Welding helmet,CUT,TIG,MIG,MMA,BX welder June 30, 2008, 2:20 am Re: Men are too stupid for welding - welding is a job for WOMEN!!!
