Reply:Weld up to the tack on both sides, Grind tack away and finish the bead.  I used a pretty good overlap to start so I had a good puddle by the time I got to the end of the last bead..  Here is the Big gap one finished.  One pass. It was over 3/8" in the center.I did not but the L bracket on. Last edited by David R; 10-10-2007 at 07:15 PM.Real world weldin.  When I grow up I want to be a tig weldor.

Reply:David, those heat exchangers are becoming a neat project for you!! It looks really good, especially considering you are stuck having to fill a gap up to 1/8" in one pass like that. Good job on keeping it from warping too much.And then, after so much work...... you have it in your hand, and you look over to your side...... and the runner has run off. Leaving you holding the prize, wondering when the runner will return.
