How it's not made...

[Arc weld]

I was watching the "How it's made" show the other day and they were explaining how an oil tanker is built. They showed 2 plates being sub-arc welded but said they pour sand over the weld to keep impurities out!:laughing: I guess I shouldn't be so surprised, a couple years ago they referred to MIG welding as soldering.

Looks like sand...

Don't think sand would pass x-ray:confused3:

....a couple years ago they referred to MIG welding as soldering

I remember that episode. It irked me so much I even e-mailed them and complained, not that it did anything but made me feel better. I like that show but blatantly wrong comments like that really tick me off.
Same watching a really good movie, one shot it'll show someone wearing gloves for instance another they're off will ruin it for me, call me wierd ....Mike

"call me wierd" - OCD is the word my wife uses

Personally, I consider it a compliment - just look at who/what passes for "normal" these days, no thanks... Steve

Yeah, with our DVR I'll say something like, "did you see that!", wife - "no" and then I'll back it up and point something out that was or was not in the last shot and she now just rolls her eyes.

If you think it's bad then wait until it is added Norwegian subtitles by one who has not the faintest idea of ​​what it's all about

 

[Shield Arc]

Only one time was I even close to submerged arc welding. Construction got slow, and didn't look good for awhile. I heard a fab shop was hiring weldors, I went and took their tests. Got put on night shift welding 24-inch pipe to 3-inch thick plates on a positioner with dual shield. Another crew was building 8-feet tall I-beams for a bridge project, they were using submerged arc. I thought it was funny, shop policy was the weldors were not allowed to run the sub arc machine, the fitters ran it. I'd go by when I could and ask questions, but didn't really get to see a lot of it.

your not OCD... Do you know how I know? If you were you'd have to spell it CDO

Sand would for sure mess up a SAW. I guess whoever was guiding the production crew didn't explain the flux situation too well. The flux is similar to that of a 7018 rod in that it has iron powder in it and much of it is incorporated into the weld. I never liked sub arc as you cant see anything that is happening under the flux so you just depend on the machine to be set right. I have seen times when the setting got screwed up and an entire pass has to be ground out because of trapped slag. That is a lot of grinding as a SAW weld puts down a LOT of metal in one pass.
