Alloys Which May be Welded as Rings

  • Iron Base Alloys
  • Nickel Base Alloys
  • Cobalt Base Alloys
  • Titanium Base Alloys

Cost Savings

Flash welded rings offer substantial cost saving advantages as compared to traditional hot rolled seamless forgings.  Each part is specifically designed to minimize material input and subsequently reduce costly down-stream machining operations.  Parts are routinely designed to allow for a maximum 0.045" to 0.060" machining envelope.  State of the art forming and sizing equipment allow for exceptional control of flatness and roundness tolerances, which enables Wyman-Gordon to manufacture the most consistent and highest quality rings in the aerospace industry.
