Hybrid welding apparatuses, systems and methods for spatially offset components

1. A hybrid welding method comprising:

directing a laser beam from a laser onto a top surface of a first component, wherein the directing comprises directing the laser beam onto an edge of the top surface of the first component,

wherein the first component is vertically and horizontally offset from a second component and is separated from the second component, and wherein along a vertical direction, a top surface of the second component is below the top surface of the first component and above a bottom surface of the first component, wherein a focus distance is a length of the beam between a laser head and a focus point of the laser beam, and wherein the focus distance is the same as a height between the laser head and the top surface of the first component; and

directing a weld arc from an arc welder onto a weld joint between the first component and the second component to weld the first and second components together, wherein the directing of the weld arc includes moving the arc welder in a weld direction, the weld direction being perpendicular to a plane comprising the vertical direction and a horizontal direction,

wherein the laser beam does not overlap with the weld joint, and wherein the laser beam promotes a full penetration weld when directing the laser beam with the focus point on the edge of the top surface of the first component.

2. The hybrid welding method of claim 1 , wherein the laser beam only contacts the first component, and wherein the first component does not contact the second component on any surface prior to forming the weld joint.

3. The hybrid welding method of claim 1 , wherein the top surface of the first component is vertically offset from the top surface of the second component by from 0.02 inches to 0.125 inches.

4. The hybrid welding method of claim 3 , wherein adjacent sides of the first component and the second component are horizontally offset by from 0.02 inches to 0.045 inches.

5. The hybrid welding method of claim 1 , wherein the laser has a power of less than or equal to 8 kw.

6. The hybrid welding method of claim 1 , wherein the first component and the second component are two different areas of a single workpiece.

7. The hybrid welding method of claim 1 , wherein the laser beam is produced at the same time as and directly adjacent to the weld arc.

8. The hybrid welding method of claim 1 , wherein the weld joint is a butt joint.

9. A hybrid welding system comprising:

a hybrid welding apparatus comprising a laser that produces a laser beam;

an arc welder that produces weld arc; and

a first component vertically and horizontally offset from a second component, wherein the first component is separated from the second component, wherein along a vertical direction, a top surface of the second component is below a top surface of the first component and above a bottom surface of the first component, wherein a focus distance is a length of the beam between a laser head and a focus point of the laser beam, and wherein the focus distance is the same as a height between the laser head and the top surface of the first component,

wherein the laser beam is directed onto the top surface of the first component and the weld arc is directed onto a weld joint between the first component and the second component, wherein the directing of the weld arc includes moving the arc welder in a weld direction, the weld direction being perpendicular to a plane comprising the vertical direction and a horizontal direction,

wherein the laser beam does not overlap with the weld, and wherein the laser beam promotes a full penetration weld when directing the laser beam with the focus point on an edge of the top surface of the first component.

10. The hybrid welding system of claim 9 , wherein the laser beam is positioned to only contact the first component, and wherein the first component does not contact the second component on any surface prior to forming the weld joint.

11. The hybrid welding system of claim 9 , wherein the top surface of the first component is vertically offset from the top surface of the second component by from 0.02 inches to 0.125 inches.

12. The hybrid welding system of claim 11 , wherein adjacent sides of the first component and the second component are horizontally offset from the second component by from 0.02 inches to 0.045 inches.

13. The hybrid welding system of claim 9 , wherein the laser produces the laser beam at a constant power throughout a weld.

14. The hybrid welding system of claim 9 , wherein the laser has a power of less than or equal to 8 kw.

15. The hybrid welding system of claim 9 , wherein the weld joint is a butt joint.
