In a method of explosively expanding a tubular metal component into engagement with a surrounding metal component, an explosive charge is disposed axially and fired in an insert comprising a hollow cylindrical container fitting closely within the portion of the tubular metal component to be expanded and having charge holding means, for example an axial pocket, to accommodate the explosive charge, the container being filled with a shock wave-transmitting liquid. Compared with solid inserts, the novel hollow insert is cheaper and requires a smaller explosive charge for a given operation. The method is especially advantageous for expanding large diameter tubes. |
