A method of connecting two components includes providing an assembly including a first component and a second component, optically sensing a connection region between the first component and the second component to produce an image, defining a substantially elliptical path in a three-dimensional space based on the image, and initiating relative movement between the assembly and welding means such that the welding means is positioned, by relative movement, along the substantially elliptical path to produce a weld between the first component and the second component.
