2 A worldwide presence through factories, offices and distributors CERAMIC BACKINGS AND THEIR APPLICATIONS . CERAMIC BACKINGS are made of sealed, high temperature (~10 to 15 cm long) for placement in metallic rails that are resistant CERAMIC , from different mineral mixes ( Al2O3, then attached to the work piece with magnets or other SiO2, Fe2O3, TiO2). When they melt, they produce a glassy fixtures. slag that forms the underside of the weld seam and seals it The CERAMIC BACKINGS offer special economic advantages against air entering. They are chemically neutral in the weld for submerged arc welding and MAG welding with solid pool. CERAMIC BACKINGS are available as CERAMIC blocks wires or metal- cored wires in the downhand position as (~2 cm long) on a flexible aluminum foil with an adhe- well for positional MAG welding using rutile cored wires sive edge, that can be stuck to the underside of the weld with fast freezing slag.

However, today they are increasingly used in pressure vessel fabrication, machine construction, general steel construction, tanks, bridges and plant engineering. APPLICATION TIPS: I deal for mechanized, one-sided welding with high Root runs welded with CERAMIC backing normally have currents and for manual welding of root runs with a lower incidence of insufficient penetration, undercut, increased welding parameters (MAG solid wire and pores, slag inclusions and restart errors.)

4 MAG cored wire). One-sided welding with CERAMIC backing increases Root runs can be produced in thicknesses that make it process reliability when root runs have to be notch- possible to weld filler layers (as from the second layer) free, in the case of dynamic loading or stress with very high currents and deposition rate, without corrosion. the risk of burn-through. Due to THEIR moisture resistance, CERAMIC BACKINGS are Suitable for compensating deviations in fit-up, without also suitable for outdoor welding . One-sided welding the need to significantly adjust the welding param- at the construction site can often be carried out on the eters, thereby ensuring a high quality root. Irregu- inside of the component so that weather conditions do lar root gaps can be welded without time-consuming not play a role adjustments.
