ABSTRACT:
A welding method that permits thick pieces of metal to be welded together over the entire face of their touching surfaces during a process of self organizing, single pass arc welding in the ambient air without any special proofing of the welding bath melt. The higher quality and faster weld when welding considerably thick metals in a single pass is achieved by using an insulated stationary consumable electrode clamped between the parts to be welded together and by scientifically substantiated selection of the value of the electric power applied to the end face of the electrode.
The arc is distinguished by the fact that the value of its power is sustained at a level which keeps the pressure of the metal vapor P.sub.me which arises due to vaporization of the electrode material in the welding zone higher than the air pressure P.sub.atm with a relation between them complying with the rule P.sub.me .gtoreq.(1.1-2.0)P.sub.atm. This affords protection of the welding bath metal melt against air oxidation and interaction with other air elements such as N, H, H.sub.2 O, etc.
