Carbon Steel Grinding Spark Test To Metal

  • Spark testing Wikipedia

    Spark testing is a method of determining the general classification of ferrous materials. It normally entails taking a piece of metal, usually scrap, and applying it to a grinding wheel in order to observe the sparks emitted. These sparks can be compared to a chart or to sparks from a known test sample to determine the classification. Spark testing also can be used to sort ferrous materials, establishing the difference from one another by noting whether the spark is the same or different. SPARK TEST tpub,The few sparklers that may occur at any place in low-carbon steel are forked, Figure 1-3.-Using a grinding wheel dresser. Figure 1-4.-Spark patterns formed by common metals.
