1 CERAMIC BACKINGS FOR ONE SIDED WELDING Refractory Materials Division in Gliwice since 1995 is manufacturer of ceramic welding backings for the formation of welding seam root passes. Welding backings are manufactured in two grades: technical porcelain cordierite PROPERTIES* TECHNICAL PORCELAIN CORDIERITE Water absorption, max. [%] 0,1 9 Bulk density, min. [g/cm 3 ] 2,4 2,1 Mount of heat introduced in the use of submerged arc melt connectors [kj/] do 3,75 do 2,73 * Given properties do not constitute acceptance a conditions 17.0/11

2 TYPE LENGTH APPLICATION 120 Ceramic backings with a concave groove. It is used when sparing between the edges is small up to 5 and when welding in vertical position. 150 Ceramic backings with a concave groove. It is used when sparing between the edges is small up to 5 and when welding in vertical position. 120 Ceramic backing with trapezoidal groove. It is used when sparing between the edges is Ceramic backing with trapezoidal groove. It is used when sparing between the edges is Wide ceramic banking with a concave groove. It is used for a large spacing between the edges 9 13 (20). Repair of defective edges prepared for welding
