Re: Cutting structural steel at site

[Subject Prev][Subject Next][Thread Prev][Thread Next]

John,

As long as the torch cutting and welding are done properly and in accordance with AWS D1.1 it should not be a problem.  Flame cutting of steel is a standard method used in most if not all steel fabrication shops during normal steel fabrication.  The real problem will be with the "As long as the torch cutting and welding are done properly...".  Hopefully you have good site inspection, QC, QA, etc.

Cutting structural steel at site





A girt that is attached to a column via steel plates is too long.

The contractor is requesting cutting the welded  plate at one end by torching it.  The girt will also be cut by a torch to the required length.  The girt will  be welded to the plate and then will be connected  to the column by bolts.


What are your thoughts please about torching the end of the girts where the lateral loads will pass thru the torched cross section to the column.

Or what is the loss to the steel grade.


Thanks,

John
