Welding 3003 to 6063. What rod ?

admin

I'm guessing it would be 4043. But that's assuming it it's properties are close to 6061, which we would use 4043. It's for an intercooler. Thanx for the help.
Reply:i think you made a smart choice, 4047 could be an alternative.

Reply:Yeah, I've got that here and it's a nicer finish than anything else I have seen locally in the 6061. It was all dull, and this at least shines a bit to match the rest of the cooler. But this is what most guys are using now. Almost done with this thing. Forgot how long to make them lol
Reply:Just have to slip rol and weld on the last tank. 3003 welds REALLY nice. Looks great when it's so shiny. Just upped the machine to 220 power. SOO much easier to weld this up lol. Don't know why I put it off for so longMako, thanx for the help.Last edited by 10secgoal; 03-21-2010 at 06:28 PM.

Reply:Thanx a lot. Hope to get faster and better as I make more. I just need to find out what's up with my stops and starts. Usually you see that oxidation, then it breaks down. On my buddies 250 syncro I noticed his completely goes away. But you can see in my second pic my stop and start, and you can see the oxidation ring. Anyone else gets that ? I usually have the balance at 76+ and the hz over 200. Wonder if my etching just isn't as wide as his settings. I've upped my pre flow to .5 and everything. Or am I overly picky ? Sorry if they are 101 questions. I literally picked the torch up one day because I wanted to tig. Only real help I'm gotten is here since I found this place.
