Vertical up

[Richard.]

Lots of good advice on here, i don't like weaving. No weaves on here. Just 7018 Low hydrogen in a heated quiver even though were in Dubai and saudi, at 40 degrees temp the humidity does the damage. This was done by a Miller gold star 602 machine. Keep practicing play with those amps up and down and you will get to what suits you and your machine. That second pass is getting there.View attachment 124873

That’s a cracking multi run there Bonser.

For your open root you need a 35* degree bevel +/- 2.5*.

⅛” gap, 3/32” root face, 85 amps, 0 arc force.

Thank you again. I will try, I did lower amps on purpose, to do like our nordic friend that weld open root 8mm gap at 55A (but with a very good welding machine)

the vid is fun, too
Usually I tend to stay on the hot side, the idea was to have more amps on the sides that when travelling in the middle, just for fun, to see if that work that way.
I was told to use a slight push or 90, and that all the slag should be under the root.

I made an Excel table where I record the amps I use for different positions and rods, as well as arc force setting (which is 10% indeed generally, may be I will need some with up head when I will be there ...)

That said possibly dirty steel I can weld better with 50% arc force, and rutilo/cellulosic rods ('we have a brand "Selectarc, the rutile all positions rods can be poured in water, bend all directions, without breaking, while it is still a 6013 a large cellulose percentage makes it their first sale - Selectarc 51 )

That is what ChuckE2009 advocates on his YouTuve videos - he really is pretty good with stick welding!

Edit : this is a triangle manipulation but with the top down.

I did not try that, sound inverted to me.

That way you begin a new triangle UNDER a bead you just laid.
Sound dangerous to me.

Christmas tree or inverted v are with a halt in the root at the top.
I use the other direction triangles and for the first bead in the corner.

But I do not understand if this is a mean to make an unique pass to join corners.

7018 rods,

 

[olek]

? I am talking manipulation, with 7018 mostly but triangle with the tip down?

You don’t need to use the triangle method with basic electrodes. The heavy supportive slag allows you to straight stringers in all positions. No need for rod manipulation.

 

[olek]

I got the point, but what is their use? Mig mostly?

I thought it was mostly a method to weld a corner up in one pass.

Very much in favour of a straight run up, start weaving about and things get out of shape near the top with excess heat (and a massive HAZ) this is talking mma like

 

[olek]

I understand that, is it may be old technology, the triangle up is considered difficult and mandatory for a qualification in Belgium. (no idea what sort)
As I did see, for non critical assembly just one triangIe pass with MIG and the weld is done

But a triangle with the horizontal side up I don't get it. Does not make sense to weld in the root under an horizontal bead. (?)

Is not this (inverted V) reduce the heat :

I am asking due to my curiosity but I will train stringer beads up (not easy to see the puddle if compared to even light wave, what shape does it have? )
Pauses, to do stringers ? (like a very light whip and bead)?

Olek i think you are looking into this far to much! My advice to you would be forget the mechanics, chemistry and everything else within welding until you can consistently throw out decent welds. At the end of everything when you go to sit a test for a procedure, unless stated you can run stringers weave etc, as long as the weld is well fused, and without voids.

Indeed this is theory, but anyway I need to have a mental picture of processes, it helps me much when training, so I cant refrain asking questions (I will try it may be boring !)
I can make decent welds, fused and without inclusions, porosities, not too common undercut , but I want them to look nicer and more even than they are (more straight, same sizes, etc) !
I did see that even pro welders may occasionally bow their line a bit, or have a defect (with stick particularly) so I am not too much stressed

making stringers without seeing well the puddle but having a nice result only because I moved very evenly, is yet pleasing, but I strive to have control on those stringers (that is, sometime less weld is poured in the bead and if you dont see well you have a miss, a smaller bead at some point.)

It is a nice simplification that today it seem that stringers are the way to go to protect the base metal, but there are many styles of manipulations, I find it interesting to understand how they work, be it to make caps they may be necessary at some occasion .

We are switching between mma and mig now, next will be TIG and it's going to get real confusing then

Heat rises, slower you move along more time that heat is input. Try and not switch processes

You've more or less answered one of your own questions by stating that you cannot see the weld pool correctly, this is probably one of the things you need to master first, would you drive your car with your eyes shut?

 

[Kent]

If you can't see it you can't weld it, I know this because I have tried many times in hard spots and a hurry and it NEVER ends well

Crud all over your lens, unable to get your head in, rubbish lighting etc.

One of the main reasons for people not having a clear view of the weld pool is they stand in completely the wrong position

 

[olek]

A few hours of padding in 2G and the puddle is back.
Notice I did not say I usually do not see the puddle it is in the vertical up that I have difficulties to see well the puddle.
A few hours padding and it will be OK.

begin with 3/32 96 98A (did not weld much for 2 months, just once)

I could not grind because it was late, so Y had to leave beads as they where, trying to correct with the next ones.

2hours later 1/8 110 115A

Indeed , I will do only stringers until it is really embedded in the hand and the eye

Yep, or just can't get to where they need to be and thier old eyes don't see as good as they once did.

And ...? You where about to say something ?
