A nice little structual job I just finished.

These beams are going down the center of the house, but are stepped in the middle and needed to be married. The first pic is the view from the deck.

Did you weld them with 6010 or 6011?

[zapster]

dont look so little to me...

...zap!

Looks like good old 7018 to me

[TozziWelding]

The web stiffeners in photo 2 were 6010, all the other joints were 6010 root with 7018 cover.

[admswelding]

why would you run 6010 on anything structural:confused?:I have never seen or heard of something that is a structural being welded with 6010 at least not to aws code D1.1

[emerickwelding]

6010 for root gets you deep penetration. If you ever do bend tests it will always be done with 6010 root and 7018 cover

What is it about the design of this house that needs those beams? Are they for the deck or for inner flooring or ceiling support?

Looks like a 14"x 26# weighin what, maybe 350#? Whats the other one? 12"x? Howdja get em up there? Boom? Man power? Looked like fun!!! Nice deck view!!Hey, when you get paid, get an LN25---

Not to hijack post but when i did my bend test on 1" plate vertical up and overhead the root and covering passes was put in with 7018. It passed on both pieces. Kevin

[admswelding]

Also when i did a bend test 3/8" coupon it was all done 7018 also.I still disagree 6010 has no place in structural welding.From what i know 6010 is a pipe welding rod.

[emerickwelding]

maybe things have been changed since I done it. But mine were done with 6010 root and 7018 cover.

[MNSTRBLDR]

I have qualified welders with a 1/2" plate, 6010 root 7018 fill and cap with no back weld. I have also given a 1/2", 7018 all the way, back ground and back welded with 7018 both with successful bend tests. Just my .02. Henry

TEK, dead on on the beam sizes, we used a backhoe to get them from the truck to the deck, and then brute force and ignorance to get them in place. There is no roof decking going on top, nore another floor. The only reason steel is in this job is for a clear span betweeen rooms. The rafters from one roof are going to sit on the edge of the beam. As far as 6010 and 7018, there is absoloutly no code on residential steel in MA. The engineer only wrote "weld" in pencil on the prints with no specific WPS. As far as the web stiffeners they were an after thought and have minimal structual value. I am looking for an LN-25, or a Miller 12rc right now. And yes, when I took my D1.1test it was a 7018 backing bead ground out, and all 7018 in the groove. Once again this is not a bridge or a battleship just a single family house that didnt want a huge wall.

Certified in structural open root,6010 root,6010 hot,7018cover.I would like to see you close up open root with 7018 with out any slag inclusion

I find it typical of engineers drawing the minimal amount of instruction. I just assembled a frame that called for half inch fillets on 3/8 inch material. They are often guessing themselves.
Low hydrogen is used on structural to avoid the possibility of underbead cracking. Using cellulose rod in the root is not normal practice however a cover pass with low hydrogen plus the action of reheating the bead underneath will eliminate the possibility of hydrogen entrapment.
The addition of the stiffeners is smart. It should have been on the original print.
At least you didn't have to do this job in the show or rain :'))
