Weaving is Better than Stringer Beads? | Stick Welding

We are back at Republic testing labs for more weld test taking with Scott. How wide can you weave when taking a welding test? How wide can you weave when welding in the field? Are Weaves stronger than Stringer beads?
Lets put them to the test and find out!

Having the ability to do both, and do them both to quality standards is a must for a good all around welder.

Stringers vs Weave...its a preference. Period. The A.W.S dosen't say one is or has to be done when taking the D1.1 or any other code. They are both welding techniques.And need to be applied where/when necessary.

On a vertical, run a weave. On anything else, run stringers. This is how it was origionally intended years ago, and still holds true now. No need to stringer a vertical unless you want to gring more than you weld. Simple as that. Anyone who says different has never used a weave on a test. I’ve never ran a stringer on a vertical, and have passed dozens, literally.

The information and data I have seen that shows stringers are superior to weaves has to do with grain structure. When you weave you put way more heat into the weld which causes poorer grain structure. On charpy v notch and tensile strength tests there would be a predicted lowering of results using a weave vs stringers. How much of a lowering and if it’s enough to bust for rod spec is up for debate (and would require specific testing). However this is likely the reason so many high liability welds specify stringers only. Excessive heat input is never a good thing, and my understanding was the AWS deals with the weave vs stringer debate primarily with heat input limits. I am not a welding inspector nor a metallurgist but all of the evidence I have seen points to stringers being stronger due to grain structure. I know when I have cut and etched my own welds I have noticed a difference in grain structure with my own eyes between weaves/stringers, which tells me there has to be some validity to it. Anyway, great video 👍

in my experience stringers penetrate better, weaves give a better appearance and coverage ...less passes .. but.. your milage may vary 😁👍🤣

Running stringers has shown a higher level of passing a bend test. It doesn't mean it can't be done, signed a CWI and 20+ year union ironworker.

I just passed an X-Ray test like this, on 1" thick plate, at 12" long, 1/8" 7018 Low-Hy. Rods, closed root, carbon arc back gouged on opposite side, fill pass, then capped. Fabrication for Oil Refineries and Power Plants.
I did NOT weave on root pass, Slight manipulation for hot pass, weaved on most the fill passes, stringer beads on opposite sides of the plate for both caps. All preference and based upon W.P.S. at the end of the day

True to many thoughs, I'v ran some stringers but my majority has been weave as well, union iron worker 20 yrs, passed all exams from NYC to booming out west and now run my own business . As long as you run tight on your ends keep a full puddle. vertical watch the shelf your good, ,,
When you have full knowledge of what the rod is doing your good ..Like my favorite forman would say : what the hand crochets the mind motivates,

[jaymccutchen]

I heard that Stringer beads are preferred over weave simply because of the heat input that causes fatigue to the steel and can fail overtime

[toker]

All of my tests never allowed weaving as a means of filling out the joint, some tests never even allowed a grinder beyond removing bridge tacks and if you reached for one they failed the test.
I guess it depends on the company you are testing for.

AWESOME WORK. Love how you melted in 4 electrodes per pass. I now know that it taks time: across... press... up a hair... press... back across... press... up a hair and press.... repeat.... Saving this video for personal improvement. Thank you for the lesson, Sir!

[abdulhameedakorede]

It isn't just all about the physical appearance but the strength also and that's what makes stringer better

[johnkizziah]

It's always better to " weave" any electrode as little as possible. Yes the code calls it a "split weave" technique

[madcapmagician]

love this argument everytime it comes up 😁👍

[armandogonzales]

Stringers are the deep penetrating versus weaving was taught that 36 years ago if you can run stringers you are a master welder weaving is much easier than stringers expierience is in the pudding guys if you can run stringers your hired

[tuivaiola]

Alot of things contribute to a good weld 1- the rods used 2- preparation on materials. Finally the welder himself must good and good

[bradysimmons]

Remember, spastically with vertical you’ve got to keep on pushing pause on the walls fast in the middle . And I learned if you stretch the puddle it lays good and flat not humped in the middle.

[jacobcarolan]

I weld my stringer with about 1/2 rod width of oscillation anyway. It wets the sides into the previous bead and makes it look clean. Works on uphill too. Idk but it bends

[NoizyBearBearOfficial]

I passed all my tests with weaves all because I forgot about stringers 😂

[WELDERMADEHEADBANDS]

Nice work Rosendo!
Great technique, as I watch I still get those testing butterflies haha, 💯👍🏽
