    a number of us have had pretty good luck on Cast 356 with 4943 filler..

    (I am a pretty recent convert myself..)
    Yes, he said that he liked a fairly "new" filler rod........I don't have my notes in front of me, but I think that it was 4943.

      As of a couple of years ago when I was welding on a Delorian engine block, Chris told me to try some 2319, So I keep that on hand as well as some 1100 rod for doing thin aluminum.

      I've been welding The dirtiest, nastiest oil soaked aluminum for 20 years so I've gotten pretty good and can weld pretty much anything that I come across.

      I tig weld all kinds of piping from low pressure to Hi pressure hydraulics and never have a leak.

      All my customers think I'm the best thing out there and I'm not going to tell them any different.

      But when it comes to Chris I still look at his work and say Wow, He is truly a Artist.

      Good luck with what ever you decide.

        2319..??? that is one alloy I have not used... seems like an odd choice..

        ALLOY 2319 is one of the few Al-Cu alloy filler metals available.. and the literature says it needs post weld heat treatment..

        any idea why he would have chosen it??... always willing to learn new tricks..

          I read the info that you sent over, The way I read it is that it is heat treatable, That doesn't mean it has to be heat treated.

          It also mentioned that it can be used for welding on castings.

          However, To be honest with you I never second guessed Chris, I just bought some and tried it.

          The valley under the intake was open and the acid from the leaves and antifreeze along with the rain water had pitted the aluminum, Not to mention another welder tried to weld the block with a arc welder and blew holes into the oil galleries and left me a mess to clean up.

            Am by no means second guessing him.... but would love to hear his thoughts on his choice...

            it might be that the DeLorean/Renault block is an Alusil casting and 2319 is one of the acceptable fillers for that high silicon alloy..??

            If you get a chance to ask him... could you share it with us??

            it does look like 4943 is a viable filler for that these days as well..
