Abstract
Official abstract text for this publication.
A system for arc welding two sides of a joint simultaneously is disclosed. By customizing welding waveforms and the distance between two or more electrodes, weld currents can be designed to transfer current to and through one or more electrodes in addition to the current traditionally passed only to the common node.
First claim
Opening claim text (preview).
What is claimed: 1. A method of arc welding comprising: providing a first current with a first welding waveform to a first electrode; providing a second current with a second welding waveform to a second electrode; welding a weld joint in an interface between a first base metal and a second base metal, each of the first and second base metals defining a first side and a second side opposite the first side of the base metal, the interface extending from the first side to the s…
