Abstract:

In a method of making a leading edge component for an airfoil device a first elongate sheet is provided and has a shape substantially conforming to a surface on one of a suction side or a pressure side of an airfoil. A second elongate sheet is provided and has a shape substantially conforming to a surface on the other of the suction side or the pressure side of the airfoil. The elongate sheet can be welded together at least along respective elongate edges thereof, in such a way as to form a leading edge base structure comprising a weld extending the length of the elongate sheets. Material deposits can be provided onto an outer surface of the leading edge base structure in such a way as to substantially cover the weld, whereby the leading edge component is formed.

Abstract:

A method of attaching a first metal object to a second metal object is presented. The first metal object and the second metal object are dissimilar materials. The first metal object comprises an upper surface and a lower surface. The method comprises: positioning the first metal object in intimate contact with the second metal object such that the second metal object is in contact with the lower surface of the first metal object; identifying at least one attachment location on the upper surface of the first metal object where the first metal object is in intimate contact with the second metal object; adding a powdered metal on the upper surface of the first metal object at the at least one attachment location; and firing a heat source at the powdered metal to melt the powdered metal and drive the melted powdered metal through the first metal object and into the second metal object.
