Welding of vessel internals with noble metal technology

摘要

Method of joining a first metal to a surface of a second metal at a region susceptible to stress corrosion cracking, comprising applying an SCC-resistant Noble Metal weld Buttering or Noble Metal weld Cladding to said first metal prior adjacent to said region prior to welding said first metal to said surface of said second metal. Alternately, a method of applying Noble Metal Cladding over existing SCC susceptible weld deposits and/or heat affected zones. A metal component containing a Noble Metal weld Cladding or Buttering over existing SCC susceptible weld deposits and/or heat affected zones.
