grinding of ferro alloys for successful chemical analysis

  • Metal Composition Analysis TestsWeld Guru

    Sep 16 2020 · The grinding wheel should be run to give a surface speed of at least 5000 ft (1525 m) per minute to get a good spark stream. Grinding wheels should be hard enough to wear for a reasonable length of time yet soft enough to keep a free-cutting edge. Spark testing should be done in subdued light since the color of the spark is important.
