Accounting for HAZ in 6061-T6 Pipe
(OP)
In CAESAR II, how do you account for the heat affected zones (HAZ) when welding 6061-T6 aluminum pipe together?

RE: Accounting for HAZ in 6061-T6 Pipe
Can you elaborate on the background of your question? Why did you think it would have influence in pipe stress analysis?
RE: Accounting for HAZ in 6061-T6 Pipe
I suppose this could be a code question because I couldn't find anything specific about this in B31.3 other than Table A-1 (Basic Allowable Stresses) does acknowledge this difference in properties. You could take the conservative route and use the welded properties for the entire length of pipe. I just assumed (there I go again), that there would be some way to differentiate between stresses in welded and unwelded portions of pipe.
Just to be clear, I'm talking about circumferential welds where pipes are joined together (or pipe to elbow or whatever). Aluminum pipe is extruded so it doesn't have a longitudinal weld.
