FINE PARTICLE PLASMA CLADING BY WELDING METHOD

摘要

PURPOSE:To thickly perform cladding by welding at the wide area without the occurrence of cracking by providing metal walls over cladding by welding thickness in advance to perform cladding by welding on the inside thereof at the time of performing cladding by welding by using welding materials containing the specific quantity of carbide. CONSTITUTION:The welding materials containing =30vol.% carbide are used to perform cladding by welding by fine particle plasma welding. In this case, after edge penetration of base material 1 is carried out so that the metal walls 3 are obtained, the aforementioned welding materials are used to laminate and clad the inside of the metal walls 3 by fine particle plasma welding. By this method, cladding by welding can be performed thickly at the wide area without the occurrence of cracking.
