The ASME codes talk about impact testing being required for temperature below -20°F unless you de-rate the material. However, it does not say whether or not the welds are subject to impact testing.

Where does the ASME Pressure vessel code end and the ASME Pressure Piping code begin?
Our vessels have pipe stubs that we weld our piping to. Which code is that first weld subject to?

It's all in what you are trained to do. I am by experience a manufacturing/process engineer with a Mechanical Engineering Technology diploma. I just happened to get a job involving a lot of structural stuff. It's not that I haven't done this stuff before, it's just been a while.
You can...
Just wanted to know how I find out what the max allowable beam deflection is? Is there a standard? Does it not matter how much it deflects? Is there a calculation?

No corrupted file, any file over 1.6MB apparently. I came up with a work around, but it's a pain. I open in AutoCAD R14, then convert to R12, then open in 2002 no problem.

I am trying to open an AutoCAD LT 97 drawing file in AutoCAD 2002, but I keep getting an out of memory error.
Any ideas? Steve Mackie, Product/Applications Engineer

Hrm, I find some of these answers going much deeper than I expected.
Whyun: No, we wouldn't do a continuous weld over the 40', probably wouldn't be much more than a 1-12 1/4" fillet. Steve Mackie, Product/Applications Engineer

Sure, the channel is a track for a roller to run in, and it is sitting on top of the i-beam. The S6x17.25 is in the usual position and the 7x12.25 channel is in the "I" position on top. There are two of these parallel about 48" apart and the wheels of a horizontal scrap conveyor...
Thanks guys, I don't have an AISC steel manual, I have a few books from Lincoln and my text books, but never really did that much structure so I just needed a little quick refresher and fast. There are a lot of smart people here that remember and do things on a daily basis that I don't.
Thanks...
Question:
If I have an I-Beam and a C-channel stacked and welded as one, to find the "I" of the "built-up" member can I just add the two "I" values together, or is there some other method of finding the combined "I."
Thanks Steve Mackie...
Consider it to be welded continuous around the perimeter. The welding doesn't really concern be, the weakest point of this structure is going to be the centre of this plate.

Oops, forgot to include that. Consider the plate to be rigidly supported around the perimeter. :) Steve Mackie, Product/Applications Engineer
