Abstract
A method and apparatus for welding a first component to a second component. A scanning head is positionally calibrated within a localised work envelope including the components, the positional calibration being referenced to at least one datum feature within the work envelope. Profiles of the components are scanned within the localised work envelope using the calibrated scanning head. A cloud point data image of defined coordinate positions of surfaces and edges to be welded within a space envelope is generated from the scanned profiles. A robotic welding torch electrode tip is scanned using the calibrated scanning head to determine a defined coordinate position of the electrode tip within the space envelope. The components are welded using the torch, the torch controlled using the cloud point data image and the defined coordinate position such that the electrode tip is held at pre-determined stand-off positions around the components during the welding.
