Thread: Length of a rifle with welded on suppressor?

I am first to put my hand up and say I dont know much about it, but I have arc welded a few thing in my day and know things get red hot and its easy to distort things if not careful. Now, I doubt you will be doing that, maybe gas welding? I dont know.

But is welding around a barrel an ok thing to do? Could it not distort, or bulge a bit inside or something bad that could leave it as a useless bit of steel tubing?
