Abstract
Abstract A method of the arc welding and deposition of metals in vacuum by means of a consumable electrode, in which for the purpose of providing the stable arcing process between the electrode wire and the workpiece, the arc is stabilized by shielding the current-carrying parts of one of the electrodes with the aid of a metal envelope having a charge corresponding to the charge of the other electrode.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
87 words
A method of arc welding and depositing metals in a vacuum comprising providing a workpiece and a consumable electrode in a vacuum opposite one another in spaced relation, said workpiece constituting an electrode, producing respective charges in the workpiece and consumable electrode to provide an electric arc therebetween, shielding the consumable electrode with a metallic envelope having opposite open ends through which the consumable electrode is movable and insulated therefrom, and producing in the metalic envelope a charge corresponding in polarity to the charge in the workpiece.
Claim 2
Independent Claim
87 words
A method of arc welding and depositing metals in a vacuum comprising providing a workpiece and a consumable electrode in a vacuum opposite one another in spaced relation, said workpiece constituting an electrode, producing respective charges in the workpiece and consumable electrode to provide an electric arc therebetween, shielding the consumable electrode with a metallic envelope having opposite open ends through which the consumable electrode is movable and insulated therefrom, and producing in the metalic envelope a charge corresponding in polarity to the charge in the workpiece.
Claim 3
Dependent Claim
27 words
A method as claimed in claim 1 wherein the charge produced in the metallic envelope is produced by the electric arc and stored in the metallic envelope.
Claim 4
Dependent Claim
29 words
A method as claimed in claim 1 including connecting the consumable electrode and the metallic envelope to an independent power supply for producing the charge in the metallic envelope.
Claim 5
Dependent Claim
36 words
A method as claimed in claim 3 wherein the metallic envelope and the consumable electrode are connected to the negative and positive poles respectively of the independent power supply and wherein the workpiece is charged negatively.
