How it's not made...

[CNC Dan]

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.

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.

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
