Joint Design "V" or Fillet

Joint Design "V" or Fillet

Joint Design "V" or Fillet

(OP)

Hello,

I am seeking a help in the subject matter. I am working on a project where Steel structure is in our scope. We have a Turbine building  where we have a Main column having Web Thickness of 25-50 MM and Flange 40-63 MM.
My query is " Can we go ahead with Fillet weld between Web and flange joint. ?" request you to kindly suggest refrence documents for the same.

Regards
Aakash

RE: Joint Design "V" or Fillet

It would depend on the loading. If there's little load then an intermittent fillet weld woudl do. In the worst case go for a full pen weld.

RE: Joint Design "V" or Fillet

The forum prefers that you post in a single category.  More information is needed to determine the weld detail.  If design force information is not available, then the conservative solution is complete joint penetration (CJP) welds.  I don't know what welding code you use, but Clause 3 of AWS D1.1, Figure 3.4 is a good start.  For 50mm (2") material a double bevel is probably the best choice, see TC-U5b in D1.1.

But, if the forces allow a combination of groove welds, fillet welds, and/or stitch welds may be more economical.

RE: Joint Design "V" or Fillet

I agree with Connectegr..., you need much more info. on the member forces, moments, stresses, section properties, etc. before your question can really be discussed in a meaningful way.  2" web and 2.5" flg. plates make for a fairly husky column section, but it is quite likely that it doesn't have to have CJP welding.  Preheat, interpass temps. and post heating might more likely be issues.  And, on columns made up of plates this thick, many times you want to mill or saw cut the ends for good bearing on the base plates.  It seems that if these types of structural design details and problems are within the scope of your work you had better know a great deal more about this subject matter than your O.P. suggests.  You really need some text books on subjects like Strength of Materials and Structural Design in Steel,  and welding ref. books to study on your own.  These kinds of questions can't be fully addressed, long distance, on a forum.
