Welding Cast Iron Beams (maybe)?

What welding projects are you working on? Are you proud of something you built?
How about posting some pics so other welders can get some ideas?

Sounds plausible. The beam was said to have been around for a while. But does shitty old mild steel develop orange skin like in my first picture?

From the look of their pictures compared to yours the closest would be tool steel! Would that be possible in an I beam? If so could it be for a special purpose? I had 2 beams that I got many years ago from an old, small backroad bridge that was dismantled that had a similar profile. :?


I'll try to do a welding test over the weekend. Thanks for that link, the spark test 'poster' is there nice.

I'm still puzzled about the material, thinking about how much it shattered the edges of the brand new cutting disc, when I separated it for transport.

Yes! Especially if it was a salt based corrosion.
I have more questions than answers

One of the uses we had for these beams was to hang one on the end of the cable of my 60ft crane and with 4 or 5 guys to swing it to use it as a battering ram to bust up concrete walls or whatever else needed to be demolished. I never thought much of it but after a lot of beating over years the beam ends were still pretty much intact. Must have been pretty good stuff certainly better than mild steel I would think. :geek:

Whatever it is, I did a little test with ER70 (S6) and looks good, no cracks or porosity. So I'll proceed and be on the watch for old cracks. Thanks everyone for the input!
