Vacuum Arc Remelting is a consumable electrode melting process used to create high grade, homogenous and defect free ingot products suitable for forging operations. Given their critical applications in a variety of industries, nickel based Superalloys ingots are commonly produced using the VAR process with a goal to maximize product quality and prevent premature failure of materials in service. However, the segregation prone nature of nickel based Superalloys means that high level of control of the VAR equipment and process is critical to ensure that ingot products are sufficiently homogenous and free from defects.

The presentation will cover:

  • Overview of the VAR equipment and process
  • Discussion of the basic control mechanisms and feedback loops
  • Basics of solidification control and segregation
  • Examples of common melting defects and their causes

Michael Lison-Pick is the Technical Manager of Western Australian Specialty Alloys (WASA). Michael has over a decade of experience working with Nickel Based Superalloys in the Aerospace, Power Generation and Petroleum Industries. Michaels experience varies from alloy formulation, primary melting, investment casting, remelting, forging, heat treatment and service repair/rejuvenation of nickel Superalloy products.
