Welding question

BukitCase · Mar 22, 2017

Went back and looked closer at the pic - I agree it's too late for MY suggestion, so I'm "re-casting" my vote for Ron's way(assuming the OTHER END of the I-beam isn't welded firm yet) - easiest way I see is to measure distance from the front of the channel to bottom of I-beam, add a "skosh" to that to allow for change in I-beam angle, mark that distance at bottom rear of I-beam web, pick a point on bottom of web even with FRONT of the channel - that'll be the POINT of the triangle that needs cut from the I-beam web - heat/beat as necessary to get the bottom end of the I-beam to close the gap, continue as Ron suggested.

That'll be at least as strong and less extra pieces to gather dirt, bug nests, etc... Steve

Thanks to everyone for some great ideas. The I beam is not welded at all so that part is good. I did just tack the C channel on top of the other, then went back and did full length welds... oops..
BUT - I figure I could cut it loose with the cold saw pretty easily and just re-weld it. I like the idea of doing it at an angle as that is pretty simple and easy. Was not planning on using that beam until the last minute so that was my big error. Never even thought of rewelding it at an angle for some reason.....

Thank you all for the ideas and info - all the ideas were really good and helpful!

Another "simple" option is to cut a couple "wedges" the shape of the opening out of 1/4" flat stock. Slip those wedges in between the beam and the channel, then just weld into place. If you need additional support under the beam, a small piece of the 1/4" stock can also be slipped in along the width of the beam. If the loads aren't too big, you could get away with just the rectangular piece of flat stock between the beam and the unsupported edge of the channel.

If you go this route I would definitely box it in on three sides and weld all the way around. Much better for any twisting or offset loads.

I ended up cutting the "C" channel and will weld it at an angle to match the beam. It is supposed to ran all day Sunday so I should get it taken care of then. Only took 2 minutes to cut the C channel off so figure that was an easy solution.
Thanks for the help all!

Well then, it is soon picture time!
