How can you weld steel and aluminum together. My 2nd problem is that it's on a sniper rifle chamber in 7.62x54r, thus I'm worried about the heat that it will produce near the weld spot and weaken it. Thanks Its a mosin nagan sniper project, and I'm trying something different, just wonder if that possible, and if not then what would be the best way secure the scope mount rather then just 4 screws?.
Tell me, exactly what's wrong with screws? If it isn't broken, there's no need to fix it.
No you cannot weld steel and aluminum. You can braze them however, which can be a very strong connection.
Aluminum and steel are completely incompatible, you really don't even want them touching due to a chemical process caused by dissimilar metals. You defiantly don't want to weld on any part of the barrel, that will kill you. The weld zone will harden and fail. An expert can braze on the barrel, I wouldn't trust anybody else to do it.
