Abstract
A system and method of welding or additive manufacturing is provided where at least two welding electrodes are provided to and passed through a two separate orifices on a single contact tip and a welding waveform is provided to the electrodes through the contact tip to weld simultaneously with both electrodes, where a bridge droplet is formed between the electrodes and then transferred to the puddle.
Claims18
A welding or additive manufacturing system, comprising:
- at least one power supply and a controller which controls operation of said power supply, where said power supply provides a current waveform to a contact tip assembly having a first exit orifice and second exit orifice, where said first exit orifice is configured to deliver a first consumable and said second exit orifice is configured to deliver a second consumable;
- wherein said first and second exit orifices are separated from each other such that a distance S is provided between said first and second consumables;
- wherein said contact tip assembly is configured to deliver said current waveform to each of said first and second consumables;
- and
- wherein said distance S is configured to facilitate formation of a bridge droplet between said first and second consumable by said current waveform, where said bridge droplet couples said first and second consumable prior to contacting a puddle during a deposition operation.

A method of welding or additive manufacturing, comprising:
- providing a current waveform to a contact tip assembly having a first exit orifice and second exit orifice,
- providing a first consumable to said contact tip assembly such that said first consumable exits said first exit orifice;
- providing a second consumable to said contact tip assembly such that said second consumable exits said second exit orifice, where said first and second exit orifices are positioned from each other such that a distance S exists between said first and second consumables;
- forming a bridging droplet between said first and second consumables using said current waveform, where said bridge droplet couples said first and second consumables before said droplet transfers to a puddle during a deposition operation.
