Weld Pattern Section Properties

[BoydZander]

I am a structural engineer. I often design welds and as such need to identify the section properties of weld patterns.

I have seen a publication called "Welding Formulas and Tables for Structural and Mechanical Engineers and Pipe Support Designers" by T.S. Hobert published by I.V.I. Structural Design Service in 1983. Unfortunately, I can not find the publication available anywhere.

Many publication offer section property formulas on 10-15 common patterns. The manual mentioned above has 68 pages of strictly formulas and tables of section properties of various weld patterns. I would like to obtain a copy of this manual or obtain something comparable. What I'm looking for is the most comprehensive collection of weld pattern section property formulas and tables possible.

So, my question is whether you could offer any recommendation on any published source that could fill this need. Regards,

Boyd Zander

I would recommend the following;

Thank you very much for your response. I actually own a copy. Blodgett is typical of most other texts in that they provide 10-15 formula for common welds.

I find that my weld groups can often be beyond the scope of commonly provided formulas. Computing the seciton properties is cumbersome.

A more substantial compiliation, such as what I described in the out of print source, is desired.

Again, metengr, thanks very much for your response.

Regards,

It should be pretty easy to set up a spreadsheet to calc the section properties of different weld groups. It may take some time initially, but be well worth it in the end. What kind of odd-ball weld groups do you have that is not covered by Blodgett?

 

[BoydZander]

The L shape and C shape of blodgett consider one side only. Often, weld is applied to both sides completely or only a portion of both side with a specified return. Often times welding is applied to the outside of one angle leg and the inside of the other. Weld can also be applied to the inside of a channel web and the outside of the channel flanges in which case a tru C section is not provided.

Certainly the effort can be put into determining the section properties of any shape and weld group, even using the basic Blodgett formulas. However, I know at one time a very comprehensive compilation of weld group formulas had been published and I'm hoping it still exists in some currently available texts.

I prefer to use hand calcualtion or mathcad with accepted formulas so anyone doing a QA review can see what computaions are being performed versus accepting that the spreadsheet is correctly computing what the preparer claims it has.

Thank you for your response StructuralEIT.

Boyd
