Why Your PWHT Pads Keep Creating Hot Spots
Why Your PWHT Pads Keep Creating Hot Spots Even When the Controller Says 620°C I’ve spent twelve years on fabrication yards and plant turnarounds around Shanghai—mostly pipe shops in Baoshan, Songjiang, and the outer chemical parks—watching post-weld heat treatment on carbon and chrome-moly welds. The complaint that shows up most is not that the ceramic pad won’t heat. It’s that the hardness readings or the temperature chart look uneven, one side of the weld is soft, and the crew blames the controller or the thermocouple. Nine times out of ten the flexible ceramic heating pad has crushed or...

Welding ceramic backing materials are used for full penetration welding from one side. In the past, full penetration welding involved costly backgouging, grinding, and rewelding. Welding ceramic backing materials are very efficient and easy to use. They eliminate costly and unnecessary gouging and grinding compared to classic welding methods.Easy Welding Ceramic is being used in the industries of Europe, Asia and now the Americas for shipbuilding, bridge construction, chemical industry and steel structures etc. Special Aspects of Easy Welding Ceramics,also can be called Ceramic Weld...
