Laser-Welded Metal Foam Sandwich Lightweights Ships

From Design News::
A new process for laser-welding large-scale, steel-aluminum foam sandwich structures for lightweighting ships, which eliminates intermetallic phase, has been demonstrated.

Lightweighting appears to be the real verb for this instance, though I agree it sounds very lazy / off in terms of vernacular use. If it's good enough for Dupont, it's good enough for me
Can I describe the term as 'makesoundlikeamoroning' if I hear it spoken aloud?
If you can manage to say that mouthful in one quick go, then I'd allow it

It was mentioned in replies to the story that lightweight is not something that shipbuilders look for because it changes the center of gravity. Lightweight aluminum superstructures are used to reduce topside weight, so a new foam sandwich material wouldn't be any better. In fact, repair would be more difficult. Although it wasn't mentioned in the article, I could assume that this new technology wasn't meant for displacement type hulls. It could be used for catamarans or ACV's, but as a replacement for current materials, I think not. There is an all steel honeycomb material that has been around for many years. It can be shaped into compound curves and is used as liners for gas turbine intakes and exhaust.
