lads these are a few 6013 caps on mild steel pipe, i know that to a lot of you guys consider them junk rods, this i think is because you are practiced in the use of 7018, but is there really the need for that extra 10,000 psi in general use, anyhow there you go. f/j





sorry i cant get the pics to attach they way i want.

Great looking cap.

[aametalmaster]

Nice pics.
Some places only let you use 7018...Bob

The main reasons, in my experience, for specing 7018 are

Low hydrogen

ductility

notch hardness

alloy matching

7018, properly stored and used, will produce a weld with a lower diffusable hydrogen level than any lo-hy rod. Very important on thicker welds ans low alloy materials

The ductility of the weld metal is significantly higher for 7018 (typ for 6013 is 18%, 7018 is 25%... source: lincon electric data sheets)

The charpy spec for 7018 is at -20F, for 6013 at 0F, and 7018-1 is spec'd at -50F. 6013 MAY meet the spec that 7018 does at the same temperature, but I wouldn't bet on it

'18 varients are available to match a wide variety of alloys (like -B3L for 1.25%Cr, 0.5Mo).



This doesn't mean that 6013 isn;t suitable for a great deal of the work that '18 is used for in the US, but it is less expensive and easier to stock, maintain procedures for, and qualify welders with, the rod most suitable for the widest variety of work.

nice looking caps, well done

very nice!!

In my 40 + almost 50 years at this trade I’ve had the privilege of working around some of the best pipe weldors in this country. Working in paper mills, food processing, oil refineries to name just a few. Your welds are a benchmark for anyone to aspire too!

[flange jockey]

thanks lads, i much appreciate your replies to my first thread, enlpck amm, i am aware from other sites that 6013 isn,t acceptable on most codes you guvs are used to, to me its standard, high temp, high pressure,and other special apps thats a different story. sonora i visit a couple of sites on the net and i must say you, as my elder have set something of a benchmark yourself, i can,t see that being beaten as a compliment. thank you. f/j

Flange, without a doubt those are beautiful welds, are they done in a fab shop and welded in one positon and then sent to a job site. They look like they are rolled or welded in a positioner. They are some of the most beautiful caps and roots that I have ever seen.

Keep up the good work,

I thought those were tig welds at first!

6013 junk?

I always scoffed at it myself...my dad loved it.
The main thing was my exp with it was using an AC buzzbox.
One day I grabbed a rod on a job (6013) while using the bobcat on DC+ and was amazed at the diff!!
What type of machine do you do these welds with and what type of settings do you use?

again thanks wheelchair, iran the roots you can see are tig, f/k and wheelchair, those butts are all rolled on sets of rollers, either using my hand and thigh, or if the pipe is a little heavier a flange key. another aspect you guys may find unusual is the use of 6013 for roots. f/k i always burn the rods i have used for those caps dc/en,they are fox sum by bolher, the capping runs are around 100 amps, the filler runs in these butts are are 1/8 rolled on the flat at 120amps, followed with a 5/32 4mm in my money at 140 amps. i hope that makes some kind of sense these pics may help, again lads thanks for your time f/j

Those are German/Austrian? Are you in Europe or UK?

Whoa...that last pic had a much better perspective with the gloves there!!
What kind of a welding machine are you using to do this? Lincoln

Very nice as usual! Most just don't have your knack for doing it. I am sure you could make a nice pipe weld with a coat hanger.
BTW it looks like I am going to be headed back to Glasgow in August of next year for the PB World Championships. Are you in or near Glasgow? If so, I usually have afternoons free and would like to come for a shop visit if possible.
Let me know and I can PM you the details.
