Interesting article as for a long time we have been struggling with interpretations of the OSHA railing regulations. One interesting thing to add to the article is that OSHA uses the term "withstand" when specifying railing required strength.
I had it clarified by OSHA and the term means : "strength to failure" not to the code allowable stress level. Important difference.
Welding low strength steel material

I need to develop a procedure for the repair of a beam at one of our hydro facilities. The beam was probably fabricated about 1912 so I am assuming an allowable tensile capacity of 16 ksi. A 1 ½ “ dia. hole was torch-cut in the top flange of the beam. It is my intent to fill the hole using a plug of material from another beam of the same vintage. The plug is to be welded to the flange using a complete penetration groove weld. Material thickness is approximately ¾”. What welding process and electrode should I specify?
