WebbSir Humphry Davy, 1st Baronet, FRS, MRIA, FGS (17 December 1778 – 29 May 1829) was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp.He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and … Webbcathode shape obtained with a free-burning arc is applicable to actual weld ing arcs. The particular free-burning arc used in this study allows long-time oper ation of an arc in a fixed position and generates a rotationally symmetric plas ma. These features permit measurement of the temperature and velocity fields with established techniques.
