Subject: Re: Welding 6061 Aluminum Mast Section Author: Brainfarth [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 14:07:19 11/28/03 Fri In reply to: Peter Medway 's message, "Welding 6061 Aluminum Mast Section" on 04:23:46 11/22/03 Sat I worked for a company that built aluminum tanker trucks and trailers and what we did for cracks was to drill holes on either end of the crack to stop it, grind a bit of the crack out then tig the missing material back in. On a situation where a doubler plate was needed, still drill the crack on either end, then weld the plate(or tube as the case may be) over it. A full weld was not usually needed for a doubler. -Mike [ Next Thread | Previous Thread | Next Message | Previous Message ]
