Moisture in low hy rods. No problems,right??

[Rig Hand]

Man I think old "hardhat" has it in for ya. And no, I didnt get on the jet fuel job.

It would appear that way, he didn't seem to impressed with the star. I don't hand them out to just anyone...... Oh well.


Everybody take care.

Na, I only need about $30 in drinks

1) because I'm a light weight

&

B) because its shinny.... so that makes me feel all warm and fussy when I walk out of the bar and she her setting there on the truck.

Did you get in on that jet fuel work?

Used that C-3 rod on a Q&T 12"sch 120 above ground steam injection line. Its liquidy alright and had to adjust the heat when capping.

Thanks for the great info Hardhat. Bob.

You get a star for the day!!!

8018-C3 is used for cold service work. It runs pretty watery compared to 7018.
I forget what alloy the C is but I know it's only 1% and C1 is 3%, unlike the chrome rods where B1 is 1 1/4 and B3 is 2 1/4 (I think that's right) That's about all I remember as I haven't used it in about 3 years.

Thanks for the star, I'll give you 1/2 one for your answers.

The alpha suffix is the chemical composition of weld deposit

"C" represents %Nickel

C-1 is 2.50%
C-2 is 3.25%
C-3 is 1.00%

E8018-C3 are used for cold service work, and extensively used for big bore cross country transmission line repair, when originally welded with automated systems (bugs)

"B" represents %Chromium and %Molybdenum

B-1 is .50% Cr and .50% Mo
B-2 is 1.25% Cr and .50% Mo
B-3 is 2.25% Cr and 1.00% Mo

Haha lol. I hate you. She was more like 1800 pounds and 35'' tall. With the bigger ones, you yourself needs $40 in drinks to justify keeping it around.

Rig Hand must be a NON-Union welder. The "H4" represents the maximum diffusible hydrogen level obtained on the AWS A4.3 test.

The AWS A4.3 Test is a Standards Method for determination of the diffusible hydrogen content of martensitic, bainitic, and ferritic steel WELD METAL produced by arc welding.

The "R" or "MR" meets specific low moisture pick up limits under controlled humidification tests.

When RigHand gets done verifying that, maybe he can explain what 8018-C3 rods are used for.

Clarification

What's up fellas? Its your good looking, vantage (w/ lights) running buddy.


Hydrogen cracking is the reason why cellulose electrodes use has been criticized on PL work. (Well, that combined with the newer X80 and higher pipe.)

Most 7018 rods end in H4R. If I remember right, it means that the rod can be out of the oven for 4 hours and not pick up more than 4 ml of hydrogen. H8R would be 8 ml.
I think it is 4 hours at "X" relative humidity but, I have forgotten what it was. I think it was 4ml of hydrogen per so many pounds of rod as well. I'll look it up if I have time.

Every one have a good weekend........except you SAE 350

Stable in strong winds! A fine quality. No teeth and pistol-grip ears would complete the package nicely.

I guess I'm just a romantic at heart.

Support group You must have forgot how good looking I am.

It wasn't that long ago I seen you hauling around a "bigger women". Looked like she weighed about 1,500 pounds and was only 34'' tall. Now that your down to a "smaller than most" 200 you want to knock the "big ones"

I guess if you prefer the higher maintenance and MUCH older type, that's fine. I bet after a hard day at work you have to buy her $40 in drinks.

Bigger/older DO have advantages:

They rarely run off and have to stop to recharge their power chairs.

They don' tell, they don't swell (well, more than they are already) and they're grateful as h3ll.

Hang a donut on your pintle hitch and they'll follow you home.

Get a fat tattooed one and you have shade in the summer, heat in the winter, and moving pictures all year long. They are cheaper than waterbeds and require less setup.

They are easy to dress. A blue or red tarp with appropriate decals and they blend in with the rest of your gear.

But if you would rather listen to the bigger women, then hey, its all you buddy. I'll take the small women all day long I dont need a fancy welder machine and a support group full of dudes to pull the small women. I wish I could be in your club, but i'll stick with the 200.

Well, you blocked my comeback with that one.

From now on, if you would please raise your hand. Us Vantage 400 MEN are trying to have a conversation, we don't have time to listen to small women & children (those who still run 200's).

I got nuthin

Yeah... You need a "large mirror" for than head. The head on your shoulders that is.

Lots of good lines in a welder pi**ing match. Love it!!

[sae350]

It was 4 days of research!!! And I don't see to many "real welders" unless I walk past a large mirror.
