I work at a facility that has been in operation for over 50 years. Some steel support in our Powerhouse has become corroded. We are thinking of welding flat steel plates on the flanges of the I-beams instead of replacing the beams. I have found some documentation on reinforcement of steel columns. This addresses welding of cover plates to the flange that are at least no narrower than the width of the flange unless a sufficient space be left for the weld. However, one beam has some holes in the web. This beam does not appear to support any weight (bending) but may have tensional (axial) load on it. We are looking to weld plates onto the web. Is there a standard or code that addresses this issue?
