Systems and methods for increasing deposition rates using multiple feed wires and deposition

A method comprising:

• providing an input electric power through an electrode wire to a weld pool;
• using an electrode wire feeder to feed the electrode wire at a first feed rate into the weld pool on a workpiece while an electrode end of the electrode wire melts input into the weld pool;
• moving the electrode wire feeder relative to the workpiece at a first travel speed;
• using a second wire feeder to feed a second wire at a second feed rate into the weld pool while a second wire end of the second wire melts into the weld pool;
• moving the second wire feeder relative to the workpiece at a second travel speed;
• and
• dynamically controlling the second feed rate while second wire feeder moves relative to the workpiece,
• wherein moving the electrode wire feeder relative to the workpiece moves the weld pool.

A system comprising:

• a means for creating a weld pool using electric power and an electrode wire that has an electrode end;
• a means for producing a workpiece by moving the weld pool along a predetermined path at a travel speed;
• a means for feeding the electrode wire at a first feed rate into the weld pool while the electrode end of the electrode wire melts into the weld pool;
• a means for feeding a second wire at a second feed rate into the weld pool while a second wire end of the second wire melts into the weld pool;
• and
• a means for dynamically controlling the second feed rate while a second wire end of the second wire melts into the weld pool.
