Welding ceramics

Our Programme

Rauschert is a leader in the manufacture of ceramics for welding technology in a wide range of application fields.

Welding back-ups, loose or customised

So-called welding chips or bars made predominantly from the material cordierite C410 and C520
Welding and soldering back-ups made of alumina C786; honed and polished for high demands
Customised welding back-ups are made of welding chips which are stuck on double-sided adhesive tape, and thus customised ready for use in shipbuilding, for example.

Welding ceramics, loose or customized Welding back-ups, soldering back-ups from Rauschert

Welding tubes and sector parts for resistance welding

For resistance welding made from the materials cordierite C410 and C520. Also made of aluminium oxide for very high-grade applications, e.g. welding bead supports

Weld studs

Welding tubes and sector parts from Rauschert Weld studs / welding studs from Rauschert ceramic-coated weld studs (metal parts) from Rauschert

Materials

Depending on the application, various materials may be used:

Cordierite C520: outstanding resistance to thermal shock; porous; low-priced
Cordierite C410: outstanding resistance to thermal shock; dense; low-priced
Aluminium oxide Al₂O₃: high mechanical strength; high surface quality; extremely high heat resistance
Zirconium oxide ZrO₂: extremly high mechanical strength; high surface quality
Silicon nitride Si₃N₄: Very high mechanical strength; age-resistant; for the highest demands
