SPECTROSCOPIC STUDY IN TEMPERATURE OF UNDERWATER WELDING ARC

Abstract

Abstract: The temperature of underwater welding arc is investigated systematically by means of spectral diagnostics of plasma. The comparison of arc temperature between underwater wet and dry welding is made and the influences of water cooling and pressure to arc temperature are considered, The factors influencing arc temperature, such as welding current, iron powder, mass fraction of thermit mixture in coating etc, are discussed. The works is significant and valuable to the study of underwater welding arc physics.

Key words: Arc, Temperature Spectral diagnostics, Underwater welding
