Abstract
A hybrid welding apparatus, and a system and method for welding at least two adjacent components having a large gap of approximately 3.0 millimeters that results in a full-penetration weld is provided. The welding system includes a hybrid welder having a defocused laser beam, an electric arc welder, and at least one bridge piece adjacent to one or more of the at least two adjacent components. The defocused laser beam and the electric arc welder are arranged and disposed to direct energy onto the at least two adjacent components to create a common molten pool operable to provide a full penetration weld to bridge the gap at a high constant weld speed, thereby joining the two adjacent components with a weld.
