Welding rod for 6061, to be heat treated
Welding rod for 6061, to be heat treated
(OP)
Hello, I'm hoping that someone could suggest a solution or a good reference for a welding rod.
We're welding a large component out of 6061, which must then be heat treated to the T6 condition.
What would be the preferred welding rod, given that post treatment properties of the weld material, and the HAZ will be critical? In other words, I'm at least as interested in trying to heat treat the weld metal as I am in heat treating the rest of the structure.
Where might I look for a reasonable value for post treatment strength in the weld zone?
I've been able to find codes for strength reductions in an untreated condition, but nothing about how much of the strength I can get back.
Thanks in advance

One alloy I've come across from some of these references is 4643. Does anyone have any experience using this rod?
I'm a little concerned about what the post heat treat ductility of this might be.
