Pipe is sand blasted normal steel 2,4mm gap and litle land 7018 root to cap.
Heres some pics how i have come litle better again.. No pics for root but it was same as betore "okay" IT REALY KEEPS ME GOING FORWARD WHEN I SEE MY PROGRESS

This is something I promised Aleksi to post, he´s planning to weld a Stainless steel test also.
So here is some pictures of a stainless pipe welded with stick.
The pipe is 2mm thick and 48mm wide, is that the correct word? I am not sure..
It is welded in 6g position.
Anyway its welded with elga 316lp, 2mm rods. Is it 5/64 in inches??

That ss pipe looks more like 5mm thick... 2mm thick pipes are near impossible with stick...

I disagree.
That looks like scd. 10 to me.
And a damn fine job.
Stainless stick on pipe is very difficult.
A common test in the U.S. for Master pipe welders is to use 309 stick to weld carbon pipe.

That is 2 mm for sure, and it is welded all the way with stick. I can post a picture with a measure if you dont believe me. 
This is very difficult at first and you have to remember, in northern europe we always use remote control when we weld with stick.
This is common test here, not everyone has it but those who can do it always have a job.
You can compare that pipe size to my fingers seen in the last picture, these photos show things bigger then they really are.

I see some companies make s/s electrodes specifically for root runs in pipe and tanks to do away with need to purge,
Avesta 4d is one.

I know this is old thread but still I was wondering, why is it allowed in usa to use 6010 to weld pressure pipe roots?Otto Nobedder wrote:It's been my experience on several forums that XX10 cellulosic rods are a US standard practiced almost nowhere else.
I have no explanation. It just "is".
In Australia and New Zealand, a 6013 root is fairly common practice, for example.

Why dont you use 7018 wich is stronger metal and the same as the pipe.
I dont know how steels are qualified around there.
Here we got this st355 steel, wich is the same as 7018 electrodes metal.
We got to use this when we weld a high quality work and as you already know, this is pretty much the only rod we use around here. 6010 in here be codes as st235 and there is no way we could use a rod that is weaker then what the base metal is.. So why is 6010 allowed in there and why you use 7018 for a root?

Svetsare,
6010 is common in non-critical pressure pipe. We also use 7010, 8010, and 9010, depending on the application. We also have 8018, 9018, even 11018.
The application dictates the filler. You hear about 6010 so much, because the great majority of pipe work is non-critical. Water lines, vent pipes, etc. Even in a coal-fired powerplant, far more than half the welds are non-critical.
