Ceramic welding process.

50 w of laser power making it more practical than current ceramic welding methods that. Fosbel has pioneered and perfected this innovative hot repair process that is used to repair the inside hot face of any furnace refractory at operating temperature in most cases with minimal disruption to production. They ensure the drawn arc stud welding process works effectively. These figures relate to silica type s ceramic welding powder mechanism of ceramic welding magma layer 3180 3540of reaction zone 3540 3720of welding nozzle projected powder reacted material in the.

This ceramic welding process is applied for more than 20 years in coke plants all over the world in the most important steelmaking group such as arcelormittal jfe china steel etc. Why are ceramic ferrules essential for stud welding. Nano tec ceramic weld powders. Ceramic ferrules also known as ceramic arc shields are small rings made from ceramic material.

Non oxide ceramics are more difficult to join by this process as they tend to react with the glazes releasing gas bubbles which weaken the bond. Usually this method is employed for joining ceramics to metals. The ceramic weld process reconstructs the refractory back to its original state. Unfortunately ceramic welding is only suitable for the treatment of medium and big cracks or holes ceramic welding together with s bricks.

The process works in ambient conditions and uses less than 50 watts of laser power making it more practical than current ceramic welding methods that require heating the parts in a furnace. Ceramic welding coke ovens ceramic welding the process from left to right. Damaged wall prior to repair welding in progress finished repair. Gas tight welding repairs reduce energy loss and solve environmental issues.

San diego ca and collaborators has developed a ceramic welding process that uses an ultrafast pulsed laser to melt ceramic materials along the interface and fuse them together. The technology works in ambient conditions and uses. It is necessary to reduce the temperature gradient in and around the fusion zone as much as possible and to carefully control the heating and cooling speed during the joining process. In many cases the cooler end.

Special glazes are available to join some of the ceramic and metal combinations. Fosbel initiated a research project to address ceramic welding repairs on older ovens that do not heat as well as designed.
