Welding question

[Code54]

Need some help from the welding gurus - how do you suggest I join these two together.

The beam is a 3" I beam, and it has to come in at an angle. I don't really have a wedge so I was looking for any ideas. I am not a great welder, but can get stuff to always hold together. This is a land plane and this is the support that runs back from the top link bracket to tie it into the rear of the plane. I am using the I beam for 2 reason. One cause I have it and is free, and the second is I want to add some extra weight in the center and figure this would help a bit.

Notch out a little in the channel so the I beam goes down some and for added support, add a vertical 1/2 x 3 up the back side. Ken Sweet

One simple way - cut the tacks on the upper short piece of channel, slip it either forward or back just enough for the sides of the channel(s) to NOT line up perfectly (but be weldable slightly offset) - then clamp that upper channel to your I beam with 100% contact, tack everything and weld it out... - the two edges of the upper channel will have differing amount of overlap with the lower channel edges, but it doesn't matter...

Cut a wedge from the web of the I beam same angle as its position. Heat and bend the flange to make full contact with the channel face. Weld all around.

It would probably be stronger overall this way than with the two channels lip-to-lip like they are in the picture. Good idea.

I like this idea too. Easy and strong , but I'd be tempted to do it Ron's (Tractor Seabee's) way.

Could you not, untack the piece that the I beam sits on and raise it ( from the inside ) to the angle needed and weld a plate there and re weld the outer section.

I also like Steve's idea, but it looks like the two channels have already been welded, not just tacked, right?

If that's the case, I'd weld it up just like you've shown it, using multiple passes to fill the gap if needs be.:shocked: No, that's not good practice from an engineering or code standpoint, but for an implement it's probably more than strong enough. If it ends up breaking, it wouldn't take much to grind it back out and use one of the more "proper" suggestions above.:2cents:

If the channels are already welded than Ron's suggestion would make more sense.

All good structural suggestions, but I like Ken's suggestion as probably the easiest. Give it some support on the raised side, and maybe close the gaps like RNG suggested.

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!
