Hi Bill,

You need not take eveything I say in my post as being personally directed at you. I try to respond to threads for everyone's benefit, to which the Vo-Tech comment is more directed to very inexperienced weldors. I figure the more experienced weldors will just ignore my comments that doesn't apply to them.

Something to consider with beams in tandum is both beams would need the same repair treatment so the design flex stays in balance. By beefing up one side of a tandum beam then this becomes less flexable and will cause the opposite beam to stress more than it's design spec thus will also split after a short time.

Once a beam fatiques to the point that it cracks, a gusset 12" on either side of the crack center line is usually what is required to make the repair. I have also seen where 6" works well depending on the location. A person needs to be careful not to tie welds or plating together from horizontal flange to the vertical web.

If your sticking your electrode while trying to keep a short arc length then your most likely about 20amps to cold. With 1/8 7018 rod you should be about 130amps or so for the average weldor. I like 150amps on 1/4" plus material. Travel speed will control small amperage speads, 10 to 15 amps. Yes there are a few joints that I drop to the 120amp range only because of the joint position in relationship to other materials.

If you post this on the tool forum then maybe BFO or Fred O. will respond as they have commented on this type of repair alot over the years. I believe both still have active shops going.
