More Information
Summary:A method of multi-pass arc welding with a consumable electrode in a protective atmosphere for welding heavy-gauge metal with narrow grooving, wherein, according to the invention the initial electrode extension is adjusted to be greater than the depth of grooving of welded joint, a current supply conductor which supports the consumable electrode passing therethrough is placed in a permanent position above the welded joint, and the welding is conducted with the length of extension of consumable electrode decreasing upon each pass, the voltage applied to the current supply conductor, rate of feed of the consumable electrode and welding speed being reduced with the decrease in the length of extension of the consumable electrode.
