I assume because you're planning on welding it you're going to use a 5 series alloy, which has a "poor" machinability rating, which may well be your problem.
I'm also on 190, which has plenty of Haas CNC mills for me to do my worst with. My alma mater team, 319, has the CNC I've mentioned, but I've never seen it run. I was intending to use 6061, but should I choose something else due to my intention to weld? Also, is it difficult to weld two different alloys together?
