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

 

[Farmerjonathan]

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.

In some languages, soldering is the word for welding.

I though MIG welding was "gluing" with a hot glue gun

You can only glue with a 110V machine. With 220V it's called soldering!

:laughing: I thought it was too.

Despite the incorrect descriptions of processes that are obvious to us in the trade, I like the show because I realize its dumbed down for the masses.

 

[bajabum]

My only objection is the description of a highly skilled person being called "The Worker"...
And the Narrator never, ever says "Eh"...:laughing:
Made in Canada, eh?
Just kidding!

 

[Arc weld]

Well you have to realize it's produced in that other part of Canada that some refer to as Quebec.

Interestingly, Sub-Arc is the only pressure ticket you can get without having to have your journeyman ticket and initial B pressure ticket first. I did a fair amount of MIG root passes on vessels and also a 7018 hot pass prior to being filled with sub-arc. The last thing you ever want to be stuck repairing (for X-ray) is sub arc burn through!ullinghair: Thankfully it isn't common but when it is, often the operator can't stop right away and the burn through is several inches long.

I worked in a shop where I guy was bragging he had his sub-arc ticket at another shop. The regular sub-arc operator was sick for a couple days and they were getting behind. They let the guy do a test and it went OK. Then they put him right to work on a 2" thick shell. The shells usually have a double bevel. A small bevel that is welded from the inside and then gouged out on the outside and filled for 100% penetration. The sub-arc operator usually does the initial 6010 root pass and then ends up gouging it out later. This guy did a beautiful looking weld... until the x-ray came back. Lack of fusion where the root was gouged out. He should have checked after going a little ways. Anyway, he had to gouge out and grind the entire weld from the outside and they got the day shift sub-arc welder to redo it. I felt a little bad for him because he thought he might lose his sub-arc ticket. He had to gouge about 1 1/2" deep to get to the problem and the shell was about 8' long.

The ones that get me are the movies and shows that show guys welding steel with an oxy cutting head with a giant yellow flame bellowing out... Or someone "trying" to arc weld with little tiny cutting goggles on...or just repeatedly trying to strike an arc, to make some sparks fly in the back ground...you can tell as the arc is constantly flashing on and off.

The show is made in Quebec and sometimes the translation is not perfect. Welding in French is 'soudage' and soldering in 'soudure'. You can see where the arts major that did the sound over probably didn't grasp the difference.

edit ....never mind, should have read the whole thread....

My sister's hubby is an anasthesiologist (might not be spelled correctly), he has spent many years in the operating room. Joking one day about soap opera TV shows in the operating room. He says many times the tubes used on the set are going into the wrong holes. LOL
