As long as you preheat enough to boil out any existing moisture of both parts and weld with a 7018 rod that is dry, it should be no problem. Use a temp stick rated at 300 deg. Regards, Carl D.

Hi All
Have a question for the welders out there. Are there any issues welding mild steel to the pressure hull ( which would be A516 70) ? I was thinking in terms of welding structural members to the outside of the sub for supporting various components and to stablize everything.
