Welding Tips and Tricks

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....

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.
