ABSTRACT:
A process is described of preparing composite articles of aluminium or aluminium alloy suitable for superplastic forming by explosion welding two or more components together and heating the welded article to consolidate the bonds. The welds do not extend into areas to which a stop-off composition has been applied and the article can be superplastically formed by passing a pressurized fluid into these stopped-off areas.
