Silicon nitride ceramic protective nozzles for welding 

   The ceramic raw material of these silicon nitride gas nozzles is imported from Germany. After shaping by cold-isosactic-pressing (CIP), debinding and  gas pressure sintering, the nozzles are grinded and polished by diamond.    MIG/MAG (Metal Inert Gas/Metal Active Gas) welding is a popular welding process that uses a consumable electrode and a shielding gas to join metals. Silicon nitride is a ceramic material that is known for its extremely high strength, thermal stability, and resistance to wear and corrosion.                                               Such silicon nitride gas nozzle is a component used in MIG/MAG welding to direct the flow of shielding gas onto the weld pool. It is typically made from silicon nitride due to its excellent thermal properties, which allow it to withstand the high temperatures generated during w…
