  • The fundamentals of gas tungsten arc welding: Preparation

    Gas tungsten arc welding (GTAW) is an electric arc welding process that produces an arc between a nonconsumable electrode and the work to be welded. The weld is shielded from the atmosphere by a shielding gas that forms an envelope around the weld area (see Figure 1 ). The GTAW process is versatile and can be used on ferrous and nonferrous metals.

  • Pyrophoricity Wikipedia

    A pyrophoric substance (from Greek: πυροφόρος, pyrophoros, 'fire-bearing') is a substance that ignites spontaneously in air at or below 54 °C (129 °F) (for gases) or within 5 minutes after coming into contact with air (for liquids and solids). Examples are iron sulfide and many reactive metals including plutonium and uranium, when powdered or thinly sliced.
