If you're worried about overheating the head when welding, then just zap 3/8" at a time and let it cool between zaps.

Just spoke to machine shop. They won't work on a car directly, but the guy sounded confident that it could be welded. Stated melting point of tool is probably lower than the prechamber. Would take an experienced welder. He did not have fear of the aluminum head because it conducts heat so well. I am going to call around on this some. Wish I could get someone over with a portable welder. Don't know if such a device would have the heat to weld into prechamber metal.
