anybody know the kind of aluminum thats used? other then cast lol... i gotta TIG a couple intakes and need to know what kinda rod to use. im pretty sure its 4043 because the 5056 wount take the heat... but im open to options lol.
I use 4043 when welding cast aluminum. However, if it's going to be anodized, use 5356. 4043 doesn't like anodizing at all. It's got to be really clean, and preheat it.
What sort of work are you doing, and on what intakes?
puddle welding on the runners for more porting room.
I'll second(third?) 4043. I have used 5056 too....
