Hi Bill,
I looked into explosion welding when I had a sump that needed repairing but couldn't find anyone to even discuss it with. From what I researched it did sound very promising but I decided to go for a new sump and dropped the idea. If you find someone that wants to give it a go, or better still give us a demo, then I still have my damaged sump they could use.
If you haven't already, you should look into how this technique came about. Engineers noticed that shrapnel from WW1 was sticking to armour plating of tanks even though it was a dissimilar material. Fascinating.
