Method for fabricating embossed articles by flash welding
First Claim
Patent Images
1. A method for fabricating an article with an embossment thereon, comprising the steps of:
- providing an article precursor;
providing art embossment precursor; and
flash welding the embossment precursor and the article precursor together, to form the article with the embossment thereon, wherein the step of flash welding does not heat either the embossment precursor or the article precursor to its melting point.

12. A method for fabricating an article with an embossment thereon, comprising the steps of:
-
providing an article precursor;
providing an embossment precursor; and
joining the embossment precursor and the article precursor together, to form the article with the embossment thereon, the step of joining including the step of solid state flash welding the article precursor and the embossment precursor together by a process that does not rotate the embossment precursor relative to the article precursor. - View Dependent Claims (13)

joining the embossment precursor and the article precursor together, to form the article with the embossment thereon, the step of joining including the step of solid state welding the article precursor and the embossment precursor together by a process that does not rotate the embossment precursor relative to the article precursor, and wherein the step of joining includes steps of applying an electrical potential between the embossment precursor and the article precursor, while the embossment precursor and the article precursor are sufficiently separated that there is no current flow therebetween, thereafter moving the embossment precursor and the article precursor together such that there is current flow therebetween, thereafter forcing the embossment precursor and the article precursor together with a mechanical force, and thereafter discontinuing the electrical potential and the mechanical force while the embossment precursor and the article precursor remain in contact.
