:laugh::laugh: I thought this title would appeal to Farmersamm

I know not all will be interested but some have not had the opportunity to run different types of rods, including myself.

Run a few rods today....7016 H8 3.2mm / 1/8
Here are a couple of pics for a tease.
Will post up details and more pics tommorrow.................:sleeping::sleeping:

How do you like running that E7016 rod? I've been experimenting with using it for root pass on high strength steel pipe, that I can't run EX010 type rods on.

How is 7016 H8 different than 7018?

With the H8 designation, the 7016 is still a low hydrogen rod even though it doesn't have the 8 in the 4th character slot in the rod number, am I right?

i was under the impression that 7016 was used for root passes, with 7018 fill and cap for cold water applications.

think thats what we used for oil rig construction for the north sea.

i liked it, but it a hole different animal than 6010 roots

Ferrocraft 16XPT
AS/NZS 1553.1 E4816-2 H10
AWS/ASME-sfa A5.1: E7016 H8
Hydrogen controlled rod.

They seem to run a little like 7018 but slag is a little more fluid. Almost self releasing, removal is very easy. Looks a little like 7024slag.

Only ran a few sticks, some 3.2mm-1/8 and 2.4-3/32

Did a couple of comparison welds with 7018 and 6013

Ran the 3.2mm at 130 amps and the 2.4mm at 85amps

No adjustments were made between 7016, 7018 and 6013.

Will spend a little more time with this rod when i get a chance.

Will be out soon to pick up some more rods.................

Is there are particular rod that someone would like to see? Let me know.

DR,

E7016 is a low hydrogen rod, with similar advantages to those you get from E7018. Better toughness, and reduced likelihood of hydrogen-induced cracking when welding on higher strength steels.

It can be used for root pass welding, uphill, as an alternative to welding with E7010 or E8010; which produce a thin(ner) root bead, and tend to be more brittle.

Practically speaking, the E7016 has more penetration than E7018, but not as much as the cellulosic electrodes. It's slow for root pass welding, as compared to downhill with cellulose rods. But if you can't make a root pass with TIG or MIG, with and ER70 or ER80 strength filler, then it's a viable alternative.

I've heard of using this with API 5L grade X70 or X80 pipe. But these aren't very common here in the USA.

To my knowledge...another use for 7016 is that its the only low-hi rod AWS appoves to be welded over galvanizing without having to remove the galvanizing. I have used it many times when welding galvanized clips and horeshoe clips for sash work on large buildings.

Thanks for posting! That's exactly what I wanted to know! :)

Sorry i dont know more about this rod,

but here is a few close ups of the page from my welding consumables guide of the actual rods i used.

The last pic is a closeup of the info for Cobalarc 750 where it gives the recomendation for buttering prior to hardfacing on certain steels.

Hope this helps some:drinkup:

LarryO,

Does the label from your Ferrocraft 16TXP show if it's possible to weld this electrode downhill? I can see that they allow for overhead fillets and grooves, but what are the recomendations for vertical welding?

Thanks.

Vertical up only it is listed at....

It actually says " all positions - except vertical down "

......and i know vertical is not a position.....................

but the missus reckons it is.:eek::laugh::laugh:


If you look at the pic in post #7, you can see the diagram in whole.
