I was just curious as I have a new test coming up on a basic single bevel plate test I think it's 3/8" I've done quite a bit of 1/2" an figured no problem, but I'd watched Jody's videos on it and my instructor said that I'll have to do a 2 stringer root, and stringers all the way out. I'd always done it similarly to the way jody does it in his video. A weave root and usually just continue with weaving. Now I understand if your tested on stringers you have to use them, and vice versa. But I was wondering why stringers over a weave??? Is it stronger? Better in some way?

I've studied up on it, and from what I can tell a weave puts in more heat, hotter bigger puddle than a stringer...
Mild steel isn't affected much by to much heat input.
Higher carbon steels, t1 and others like stringers...
Yt channel "Brazil welds" has some great videos on stringers on pipe..

I personally like a weave...
Stringers it's hard for me to see the puddle, the wetin, the undercut...you just go straight up.
If your plate test has a 1/4" gap with backer bar, it's gonna be tuff to stuff to stringers in there...

Plenty of better opinions than mine....
Just a couple welders and a couple of big hammers and torches.

Like AK said, it's about heat input.

If you look at this equation, faster travel speed (all other things equal) means a larger number in the divisor.
This means a lower heat input - and for some jobs the Kilojoules per inch matters.

Yeah AK that's exactly what it is....1/4" spacing and a backing plate....I feel pretty confident about it but I personally think it's much harder with stringers just cuz it's real easy to squeeze your rod out of the other side. It'll definitely be worth practicing I suppose. I'm really trying to get these welding tests out of the way so I have more time for all this freaking homework I got to do. I've had 3-4hrs of homework every night, and they expect you to weld 20-25hrs a week in their shop, and I gotta work.

I can't remember the exact bevel but it's pretty steep anyway.
