Hydrogen content in low-alloyed weld metal in twin-arc welding
G.V. Bursky, M.M. Savitsky
E.O. Paton Electric Welding Institute of the NASU 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine.Abstract
The effect of twin-arc welding on hydrogen content in low-alloyed weld metal was investigated. It was established that, as compared with a single-arc welding, the twin-arc welding can decrease significantly the amount of [H]diff in weld metal that is due greatly to the peculiarities of the thermal cycle.
Keywords: hydrogen, single-arc weld deposit, twin-arc weld deposit, thermal cycle, cold cracks, humidity of shielding mixture, time of hydrogen evolution
