Aluminum Weld Shear Strength?
Aluminum Weld Shear Strength?
(OP)
Here's an easy question. I'm using 4043 to weld two 6061-T6 tubes and I'm trying to figure out the strength of the weld. I've found some literature that says the minimum shear strength of a weld using 4043 is 15 ksi. Does that figure include the weld efficiency, or would I need to knock that number down even further?

Consider a full pent weld and HT if full strength is required.

Welded butt joints.
Minimum expected strength. (Called design point by ALCOA)
Welded with no post weld heat treatment.
6061-T6 welded with 4043 under 3/16" thick:
UTS 24,000 psi YS 20,000 psi
6061-T6 welded with 4043 over 3/16" thick
UTS 24,000 psi YS 15,000 psi

Minimum Shear Strength of 4043 Filet Weld after naturally aging 2-3 months.
Shear Strength 11,500 psi
