Certainly a very interesting process and may have some potential applications for us, though I'm with Dennis concerning the problem of the typical thinness of our boiler shells. It may be possible to overlay a sheet of material at the hole location and thus establish a suitably thicker wall locally. This process does remind me some of using ultrasound to "weld" brass inserts into plastics which I was told could also be done in some metals in a much heavier operation with much more expensive equipment, but I'd never experienced that end of the spectrum.
