Can you please tell me what mean the guy in that 7018 text from Lincoln where he state :
"When welding the second pass, use a weaving motion or stringer technique. If you opt to weave, think of the number 8 sideways and move from left to right. Also, pay close attention to the bead width when using the weaving technique. Try to keep it at ¾" or smaller for the maximum width overall after multiple passes. For the stringer motion, create the letter “I” and follow in a straight motion "

(That mean a stringer then another next to it ? It is not a "ladder" )
As I don't know the direction of the weld, I thought that for the 8 this is a normal 8 may be a little pinched that goes from left to right recovering itself (?)

Thanks if you have a little time for that. I do not get well the restart explanations, too (I do not understand what is particular in his description of restarts)

Just don't get too into what you're listening to on the I pod and use the stinger to crash the cymbal. That makes a mess. :lol:

Yeah I hear you on that. I will rarely listen to music when I weld. Usually tig welding since it usual is a little quieter at least for DC. And I try to wear ear plugs to and even without ear plugs I don't need any more noise. Although it would be pretty funny to watch somebody do a nice cymbal crash.

And I know never to get to comfortable running something. That's when undercut, slag inclusions, and all the other fun stuff happens.


Farm weld, I may admit I have no idea of the type of training you did attend. Was in a welding school, a "camp" ?
(Just curious)
As I was stressing too much at the beginning I used to listen to music I like , could be salsa, reggae, rock, it helped me to move more supple. I stopped after a while and concentrated more on the sound of the weld and welder machine.

Well next year I'll be a senior in high school but this last year and next year I got/get to take classes at my local tech school, but in this instance I was not taking an actual welding class the last semester because of a dumb pointless class...either way a welding instructor that teaches there came down with a box of 3/32" 7018s that were crap we found out but I saw him a week later and told him and he said to come up and he'd show me some stuff and then threw me into the fire...literally and figuratively. So it was a lucky shot that I happened to see him and he liked me and I can at least make it seem like I know what I'm talking about
A student now but really want to weld everyday. Want to learn everything about everything. Want to become a knower of all and master of none.

This is an example of stringers.

Thanks, Farmwelding, you have been lucky I suppose it is normal sometime ;) best of luck for the next year .!

The stringer : no manipulation or very little there ? Is the upper weld 3 times the diameter of the rod.

No way to test those types with penetrating dye I suppose. ?

What 'tricks' are possible to repair or correct undercut ? Farmwelding seem to say something about...

Thank you

It's an odd picture angle. Those were welded with 3/32 7018 and the bead is about 1/4 wide.

I was not far it is almost 3 times no ?

Did you do that by dragging very slowly and straight around, or with a very small weaving ? That is about how much Amp ?

For the short arc I am at it from the start, I think I even had too short an arc with the 6013 sometime Wich make the puddle touch the rid then may be try to pass behind or make inclusions.

I prefer 7018 . Now is it possible to have a too short angle ? Is gas shield insufficient then ? Sorry for the many detailed questions , I weld "in my head ": before going real ;)

Yes you guessed close on the size, those were made with almost no manipulation. Mostly a drag angle but some changes to a 90 deg angle and then a push as I go around. I've only run about 10 lbs of 6013 but I noticed its possible to get slag inclusions. It's also possible to get that with 7018 but my experience with that is that it was from weaving too far or too fast. The gas shielding with stick happens right at the point that the flux burns off. It only creates a small pocket of gas hence the need to keep your manipulation small or weave at a slower rate. You can make wide weaves over 3/4 of an inch wide even with 3/32 rod you just need to weave slower.

Thanks Josh those are great details, they help a lot ;)

I was not expecting you could go 90 and even more to push while keeping the weld free of slag . You still touch the base l'étal when pushing ? (At 90 I guess no)

I will look at the puddle plus the gas shield together I think . You see the gas shield moving the surface of the puddle (7018) or is it only the metal "cooking" as we can see under with 6013 ?.

What your seeing is probably the slag as it mover across the puddle and starts to form. There's a little bit of an art to seeing the slag and yet seeing what the puddle looks like underneath that.
