Abstract
A process and apparatus for forming an as-rolled composite metal panel comprised of at least two sheets of metal having a bond therebetween which can be broken by inflation to form a desired pattern of tubular passageways. The deformation of the sheets of metal during inflation is limited by a maximum aspect ratio. Inflation is provided using an inflation needle having a cross section which is a part or full oval. A fixture is provided for limiting the peeling apart of the composite metal panel upon insertion of the inflation needle.
