RE: Existing Welds, Guidelines for Increasing Size

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Even for new construction welds are often performed in multiple passes.
Adding weld should not be a problem within the constraints of AWS.

Now if the question is restraint or reinforcing the member under load or
residual forces, you need to look to the articles by Ray Tide of Wiss,
Janney & Elstner http://www.wje.com/services/.  Check out their web site.
They will fax you the articles on request.

I asked them to post them on their web site.  I don't know if they have done
that yet.

Subject: Existing Welds, Guidelines for Increasing Size



Do guidelines exist for increasing the size (and thus the strength) of
existing welds?  The existing structure has A36 steel, E70 electrodes and
fillet welds.
