That's crazy! Sometimes I just underestimate the immensity of stuff in the industrial world!

He should have used a Mitech 40, would have sliced right through it.:smokin:

it's cool but wtf does anybody need a 10' thick piece of steel for

If you do a quick search for the first "big welds" post he explains that they are repairing big forging dies, hammers and bases. The piece gets a big crack all the way through it so they gouge it out with a torch, then fill it with layers of weld. Its cheaper than trying to ship a new 450,000lb chunk of steel from overseas since no one in the US casts them anymore.

That is absolutely insane setup he used to weld it with; I love it! :smokin:

[dkc1657]

It's pure insanity so awesome!

I've gotta say that I've since picked up a plasma cutter but I still like flame cutting ... I like the feel and control of a big brass long torch handle compared to the feather-light plasma cutter plastic end.

Damn, I thought that was a typo and ya meant 10".

that makes sense. but still a big ass die. i worked around 100 ton presses and iirc they where 2-3" thick dies. i can't imagen how big a press this thing goes to.

[StinkBug]

he said it goes to around 50,000lbs I think, but keep in mind thats the weight of the hammer thats being forced down into it repeatedly. Not just a static pressing action.

anybody got a link to the first thread, the search appears to be down on that site now.

While some of my descendants from Newport News had 2' chain links and clevis that looked big enough to use as a hula hoop...I just want a 3/4" electrode:eek: :laughing:

I worked with a 30 foot 400 ton press brake, had about the same size die's 2-3" thick.

That was cool. Thanks for posting that link.

Years ago when I worked in a press shop (stamping auto parts) the dies were pretty hefty. We were using 500 - 4000 ton presses.

The big 4000 ton dies were often 12"+ thick.

Check out those 3/4" electrodes....:eek:

THAT is the second coolest thing I've ever seen!

Did you get that from that other message thread or is that you in the picture?

I wish I could say I've welded with an electrode that is width of a pool cue....but THAT IS NOT I.

I think that pic is on the 3rd or 4th page of the link in the 1st post of this thread.

[hoohaa]

That's a piece of metal.

Electroslag Welding is the process. It's amazing to see. They pretty much just keep a molten puddle in the center that is created by feeding in those electrodes the slag comes to the top and then you can mill it off or air arc it.

[ZJim]

Pretty soon they'll be able to cut you a buggy frame out of a huge chunk of steel.


:D

[NitroRClover]

Too badass.

[pepe]

I believe the cutting process is oxygen lanceing FWIW. But the welding process looke like SMAW, not electroslag. I thought electroslag ran off a wire feeder?
