Do you V for butt welding 1/4" material?

[Haywire]

Title pretty much covers it. That "favorite rod" thread got me wanting to get better with 6011.

I was butt welding some 1/4" scrap using 1/8" 6011 at 100a and wasn't getting penetration to the back. I left a gap of about 1/8". It was DCEP. Judging by the penetration I got, I figure if I V groove it about 1/8 deep, it would get full penetration. Oh, no backer. I used other scrap to space it off the table.

hmm.. 1/4" material, 1/8 6011 rod ( not 6010? ) adn 100a

I think you should have been able to get full penetration without v grooving, whether it needed it or not.. etc.

had you said 6013, i'd have agreed completely.. a bit of a shallower weld..

Maybe I was traveling too fast and not allow the puddle to penetrate. I dunno. I'll take some pics.

for dc, 6010 works better then 6011, and it welds basicaly the same, just a bit less spatter.

The camera on my phone sux.. none of the pictures turned out. It's raining, so the good camera isn't going out here. I welded some more with 1/8" 6010 at 85a and 1/8" 7014 at 130a with similar results though.

The 6010 runs smoother than the 6011 but it's harder to keep an arc going.

Since you have an Everlast PowerArc 200, have you tried the 6010 port for both the 6010 and 6011 tests?

It is supposed to help but since I run only 6011 it is hard to compare.

I do when I want 100% penetration!
Depends on what level you want to take your welding / fabrication skills to. You'll need to figure out what angle of bevel, land, (root face), and gap works best for you. Two double bevel plates are easier to get full penetration than two single bevel plates.

I have the newer version that doesn't have a separate 6010 port. The 6010 capability is supposed to be built into the standard port now.

Well that's good to know. Maybe (just maybe) it isn't all my fault then. I'll try beveling a few pieces and see how it goes.

Joint prep, will make or break you! Even the best weldors in the world can only do so much with bad joint prep.

Here's some stuff on rods.

I don't have any pictures of how I like to prep my joints for open root welding. I do for Tig welding, but not stick. Here is a picture of how I like to prep for open root with backing plate, this is vertical up with 1/8 inch 7018. For open root stick welding plate or pipe, I like 37-degree bevel, with 1/16 inch gap using 1/8 inch rod. Now the land, (root face) depends on which brand of rod I'm using, it can vary from 1/16 to 3/32 inch.

I did find these.

Hehe.. my beveling involves eyeballing it with a 4" grinder. I gave it a whirl and did get closer to complete penetration but still not quite there. Needed a deeper V. Tried capping with 1/8 7014 but it piled up, should have used the smaller stuff or moved faster. I'm running out of scrap too. Need to make another run to the local welding shop, return this bunch of scrap and get some more.

Is there any disadvantage to using 7018 that hasn't been in an oven, or do you just lose the low hydrogen qualities?

When you have time read this thread.

Amen to that

I keep saying that to my brother when he asks me to weld for him (i learned it from him as a kid) because his welds dont stick... especially in rusted or painted material, prep work makes the stick... If the rust is into the pores of the material, i certainly V it (mostly after tacking together i run the disk through the seam) because its harder to penetrate dirty material.

That said, i am pleased with the extra punch of my new 350A light industrial welder, over my previous 180A hobby machine... It sure does help to get penetration in thicker material.

Thanks SA. First line of that thread told me what I needed to know.

Went and got some more metal and tried my hand at vert up. It went better than expected until I did a darn fool thing and flashed myself. Was using 7018, finished my weld, flipped up the helmet, and realized I had forgotten to flick the kernel off before it cooled. I looked right at it and tapped it on the vise --- that my ground clamp was attached to --- . Idiot.

Remember now, 7018 will run oh so much better when kept at 250-degrees minimum.

 

[Haywire]

Now 5/32" 6011 at 150a almost (but not quite) penetrated without a V groove. Just a small gap of about 1/16. You can see the weld on the back side, but it's just a bit down in the crack.

:laughing: I can laugh because I do that myself. :laughing: I also have grabbed hot metal without a glove after I got done welding. I've burned my hand many times doing that. Though not bad. :thumbsup:


I was welding my pivot for the swing on my backhoe and as soon as I got done welding it I grabbed it with bare hands (was gonna check fit) and I dropped it that instant.

I think I need someone to tell me no, that's not safe when I'm near hot things. (Like when I was little) I guess I never grew out of that stage. :laughing:

No sandy eyes this morning, I guess I lucked out.
