Thread: Length of a rifle with welded on suppressor?

Re. aluminium suppressors, normally the aluminium would come off worst (be the anode) in a steel:aluminium pairing. So in your example I'm sure there can be corrosion, I just don't think it would be galvanically driven to attack the steel.

ADDED: Anyway, I like Gundoc's idea of high strength loctite. Apart from avoiding some of the potential issues with welding, done properly it would also be a sealant at the suppressor/barrel interface and prevent corrosion in these joints.
