Bolt Hole on CJP weld line 1

[nymous]

I need some sources or references to sustent my position in order to reject a steel member which has a shop welded splice with a bolt hole located on the line of welding. The joint is a CJP and is joining WF shapes.
Thank you in advance for your help.

Regards.

Nymous.

If your feeling is that the steel member should be rejected you are probably right and you should be encouraged to follow your opinion.
In general, however, to decide on such a matter, a stress analysis should be performed that takes into account the direction and amount of stresses in relation to the weld.
Furthermore it would be important to establish if the steel member is subjected to fatigue stressing.

I'm showing considerable ignorance here, but what exactly is the problem? I know we don't like it, but the weld and the hole are both fatigue category B.

Nymous,
Just a quick question here- I am wondering why you are looking for substantiation to reject something instead of tools for evaluation to see if it will really cause a problem or not?

Anyone have an answer for my dumb question above?

No one can answer the problem without
knowing the application and how the
hole is used or even the forces that
are acting on the weld. The problem
is too vague. What forces are acting
on the weld design?

Just in general, though, there's an overall idea that "drilling through welds is bad". Let's assume tension across the welded splice, with a bolted bearing connection.
