Abstract

A dual-weave welding system is disclosed. The system may have a first welding device configured to create a weld joint in a gap between two or more work pieces by moving a first welding component along a first weaving path. The system may also have a second welding device configured to create the weld joint in the gap by moving a second welding component along a second weaving path. The system may further have a controller that sends commands to control the movement of the first welding device and the second welding device.

Claims (65)

1. A dual-weave welding system, comprising:

a first welding device configured to create a weld joint in a gap between two or more work pieces by moving a first welding component along a first weaving path; and

a second welding device configured to create the weld joint in the gap by moving a second welding component along a second weaving path.

2. The dual-weave welding system of claim 1 , wherein

the first welding device is a laser welding device and the first welding component is a laser beam; and

the second welding device is an arc welding device and the second welding component is a consumable electrode.

3. The dual-weave welding system of claim 2 , wherein

the first welding device is further configured to create the weld joint by moving the first welding component along the first weaving path with a first frequency of oscillation; and

the second welding device is further configured to create the weld joint by moving the second welding component along the second weaving path with a second frequency of oscillation that is less than the first frequency of oscillation.

4. The dual-weave welding system of claim 3 , wherein the first frequency of oscillation is between 0 Hz and 3.5 Hz and the second frequency of oscillation is greater than or equal to 4 Hz.

5. The dual-weave welding system of claim 1 , wherein

the first welding device is an arc welding device and the first welding component is a consumable electrode; and

the second welding device is an arc welding device and the second welding component is a consumable electrode.

6. The dual-weave welding system of claim 1 , wherein the first weaving path has a first amplitude that is less than a second amplitude of the second weaving path.

7. The dual-weave welding system of claim 1 , further comprising:

a controller configured to:

receive input parameters defining a first frequency and a first amplitude of the first weaving path and a second frequency and a second amplitude of the second weaving path;

send a command to the first welding device to move the first welding component along the first weaving path having the first frequency and the first amplitude; and

send a command to the second welding device to move the second welding component along the second weaving path having the second frequency and the second amplitude.

8. The dual-weave welding system of claim 1 , further comprising:

a controller configured to:

receive input parameters indicative of a size of the gap between the two or more work pieces;

determine a first characteristic of the first weaving path and a second characteristic of the second weaving path based on the size of the gap between the two or more work pieces;

send a command to the first welding device to move the first welding component along the first weaving path having the first characteristic; and

send a command to the second welding device to move the second welding component along the second weaving path having the second characteristic.

9. A method for creating a weld joint in a gap between two or more work pieces, the method comprising:

controlling a first welding device to move a first welding component of the first welding device along a first weaving path; and

controlling a second welding device to move a second welding component of the second welding device along a second weaving path.

10. The method of claim 9 , wherein

the first welding device is a laser welding device and the first welding component is a laser beam; and

16. The method of claim 9 , further comprising:

receiving input parameters indicative of a size of the gap between the two or more work pieces;

determining a first characteristic of the first weaving path and a second characteristic of the second weaving path based on the size of the gap between the two or more work pieces;

sending a command to the first welding device to move the first welding component along the first weaving path having the first characteristic; and

sending a command to the second welding device to move the second welding component along the second weaving path having the second characteristic.

17. A dual-weave welding system comprising:
