I've seen a product you can buy like that but it is slotted on the base to slide onto weld on T shaped lugs. Then it's easy to remove to put on another T lug. You knock the lugs off after you're finished. Welding nuts on a piece of heavier plate in an L shape and using a bolt as a hold down is common. Most people call them s_crew dogs. When you weld them on, you put the weld on the front edge(inside) as that's where the force is. Then they're real easy to break off after you're finished. Loosen the clamp so there's some space between your work piece and either pull it forward or whack it with a hammer and the weld will rip off. Sometimes you have to twist it back and forth if you put a big weld on it. On your clamp you could cut off the plate sticking out the back of the clamp cause it isn't needed. If you welded that side down to clamp, it would just bend up using the weld like a hinge when you applied clamp pressure. Putting the weld on the inside, you'd be surprised how much the weld will hold.

That's funny Stick welding! I just mentioned the same thing on another site, except I didn't go into such detail. I said it was the same thing as using dogs and wedges.
Great minds think a like! :wink:

I don't know if I've got such a great mind. Thanks for the compliment though. LoL I probably go into too much detail because I figure a lot of people don't realize what's involved to fabricate some of the big stuff.

You use a lot of dogs and wedges fitting vessels. Wedges are used for the heavy jobs like fitting 2 1/2" thick heads. Most times you can just weld on one side like in your picture but sometimes you have to weld both sides and grind one weld out to break it off. Really heavy jobs need hydraulic porta-powers to put things in place.

I worked in a vessel shop that had a 10' diameter, 2 3/4" head weighing over 10 tons fall off and partially crush a wire feeder. It put a hole in the concrete floor as well. A lot of wedges were used to fit it and it was fully tacked in place for the root pass but must have been under a lot of stress. Tacking isn't really the right term. When fitting thick vessels you lay a piece of round bar in the bevel and put a weld down each side so you don't burn the edge for your root pass. The round bar is 1" to 1 1/2" long and you put a 1/4" gap rod between the 2 bevels for 100% penetration. We heard a ping, then another ping and it didn't take long to realize the tacks were breaking. It was almost like slow motion, then BANG! We saw the wire feeder and XMT 304 cart sitting there but you don't take chances with a 10 ton chunk of steel making strange noises. The tacks were about 6" apart all the way around! I helped fit it back on and got to do the MIG root pass. Had to use a tiger torch to preheat it but man that was a lot of grinding! You start your root pass between the tacks and grind out and clean up every piece of round bar as you go. You also have to feather your root pass every time you stop. Once the root pass is done you grind all your stops and starts and run a 3/16" 7018 hot pass so hopefully the sub-arc won't burn through. Fixing sub-arc burn through for 100% X-Ray isn't fun and neither is grinding off all the welds from the wedges. LoL


For pulling checker plate up on skids when they're upside down, we just used a piece of pipe with about a 2" wide flat bar on the end. In that case you tack the back side of the flat bar on the checker plate and place the other end on the I beam. Then just use the weld as a hinge and pull the checker plate up and tack it in place. Pull the pipe handle back and it breaks the tack so you can move to a new location. Very fast and because the tacks are on the bottom and nobody see's them, you don't normally have to grind them off.

Using round stock like that, we always called them bridge tacks.
When we started this project just down river from the Bonneville dam on the Columbia River I had a fab shop in Portland Oregon cut out enough wedges and dogs to fill a 55-gallon drum for each. Takes a lot of dogs and wedges to align 10-feet dia pipe. Had to have a tent made for the weldors, they were running dual shield, that wind can really blow through the Columbia River gorge!

They are kind of a bridge tack. On smaller pipe you just put bridge tacks with MIG without the round bar because you can keep the weld away from the edge of the bevel. The round bar bridge tacks are always done with 7018.

That bicycle must be a poor mans weld tractor. You hold the flux-core gun in one hand and pedal the bike the opposite way while turning the pipe. See we can learn something from Hamsters. LoL

Did you ride the bike all the way around the inside of the pipe???LOL!!

No, :lol: I didn't even take that picture. That was in General Cascade ship yard on Swan Island in Portland. I started there over seeing the ship yard workers put a crawler crane on a barge for us.
