Abstract
A welding system and method is provided which moves a welding consumable during a welding operation, where the consumable is moved downstream of the welding contact tip during welding. A wire manipulation device is provided which causes the consumable to move after it has left the contact tip and before the consumable reaches the weld puddle of the welding operation. The consumable can be moved in different patterns during welding and the welding process parameters, such as wire feed speed, etc. can be changed based on the movement of the wire.
Claims20
A welding system, comprising:
- a welding power supply which provides a welding current to a welding consumable during a welding operation;
- a welding torch comprising a contact tip where said welding consumable is delivered to said welding operation through said contact tip;
- and
- a wire manipulation device comprising a wire manipulator and a mechanism to move said wire manipulator, where said manipulator is positioned between said contact tip and said welding operation;
- wherein said manipulation device moves said welding consumable downstream of said contact tip relative to a centerline of said contact tip.
