ABSTRACT:
A method for the manufacture of hollow articles comprising providing a first sheet of metal, placing on said first sheet a weld-inhibiting material in a pattern corresponding to a predetermined configuration of fluid passageways, forming an assembly by superimposing a second sheet of metal upon the surface of said first sheet bearing said pattern, pressure welding said assembly in the areas thereof not separated by weld-inhibiting material, and expanding the areas separated by said weld-inhibiting material, wherein the weld-inhibiting pattern provided is so configured that when said assembly is expanded, a marker structure is formed which is situated so as to guide the determination of the final linear dimensions of said article. The foregoing marker enables the rapid, automated sizing of articles such as heat exchange panels produced by the above process.
