Ceramic Weld Backings
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.
Using ceramic backing materials makes it possible to weld in the spray-arc mode. Due to the higher deposition rate the welding is more efficient. Different kind of ceramics are available for various types of weld preparations. With X and K preparations usually round ceramics are used. For plate material the grooved ceramics are standard.
Ceramic backingare used in the following industries :
- Maritime constructions
- Other steel construction
