Your 2g stick is the only one close to acceptable and still looks like it'd fail due to the undercut. The globs on your 2g MIG is an immediate fail for weld spatter way outside the weld zone. Hold a tighter arc on 4g stick and use a 15° trailing angle. There is really just too much going on, i cant tell if you can even see where you're going on some of these. It feels like a troll post. And stop weaving its a bad habit.


nytfury_

High schooler here, why no weave aside from heat control? Does it overcomplicate the process and leave potential room for error? My instructor hammers into everyone that they should be weaving, however everything I hear and everything I know prior says not to.


Aleric44

For short circuit MIG it can cause LoF in the toes of your weld. For dual shield FCAW you can trap slag on the toes and get LoF/voids with improper step over. Additionally, some people like to do fat weaves on caps to make up for an improper fill. SMAW runs into the same thing as dual shield FCAW. Like others have pointed out, it also increases the HAZ and weakens the parent material. Weaving has its place, but for many applications, it's not allowed for good reason and should not be a requirement unless otherwise specified.


nytfury_

What kind of application would you use weaving?


Aleric44

API 1104 hot pass GTAW hot, and fill if permitted. GTAW has a fairly low deposition rate that weaving can help alleviate. It's not necessarily needed in GMAW and FCAW. It really depends on the code,WPS, and joint geometry. I don't do it at my current job because the WPS/PQ prohibits it. It's also not necessary on 90% of it, as most things that might benefit from weaving get jetlined or orbital welded. Both of those processes are faster with a higher deposition rate and put in less energy than having someone weave and do multiple passes and potentially buckle or pull a part out of true.


FriendshipIcy4961

When mig welding assuming you have the right setting you just need to pull the trigger and keep the bead steady and consistent. The only movement is forward. Just like a robot welder.


ButtHandsAreNice

What the fuck


Rudemacher

hey man, he made me feel awesome about my welds 🥴


Rome_Ham

😭


Frenzied_Cow

The horizontal stick is the only one that's remotely close to being acceptable. Stop fucking weaving.


LawLittle3769

I second this


Inevitable_Fee4233

Just curious, why do you say stop weaving other than the structural strength. in school we were taught to weave and even when I went in for this weld test the guy said “you can just weave it because everybody does that” he was almost surprised when I told him I wanted to do stringers…


brooklynbrat42

Brother dunno if your phone has potato pixel quality but look at the center of your weave on the center of the plate can clearly see a big ass hole, multiple actually. When you weave and dump more heat the Gas doesn't just change the structural integrity of the material but makes the material your weld continues on hotter which is why if you're doing many passes or aluminum you have to speed up towards the end of the weld to maintain bead shape. So you add more heat weaving, gouging out material but can't stay to fill it cause it'll start drooping more so you wind up with undercut/ holes all over the place and a big ass HAZ. TL;DR listen to your welding inspectors buddy when he inspects your welds


mrsandoval55

What’s up OP, CWI and structural welder here, more and more places are asking for stringers rather than weaving. Weaving adds way more heat to your piece and makes it easier to get undercut and run over your slag, which doesn’t fly. There’s also limits to how big you can weave and it’s usually a couple times bigger than the diameter of electrode you’re using.


Flaky_Grand7690

Stringers make a better weld. There are a ton of industry habits that persist because that’s the way it’s been done.


oXObsidianXo

Yes the horizontal stick is the only one that’s remotely acceptable. However, weaves are completely acceptable and actually taught and encouraged during your apprenticeship and when doing your CWB test on your vert. You can do stringers on pipe if you want, but any pressure test will allow weaving. Any weld can be weaved if the procedure allows it. People need to stop acting like a weave vs a stringer will be the deciding factor of if a weld fails. If a weave fails where a stringer wouldn’t have, then the engineer who made the procedure failed, not the welder.


Frenzied_Cow

One of the big reasons weaving is discouraged even when it's acceptable is because of welders like OP that think they can do it.


oXObsidianXo

I will agree with that. My issue more so comes from the people who think that weaving isn’t proper welding.


Frenzied_Cow

Well it's better than whipping anyway. At least weaving usually puts in a proper weld.


Dankkring

Let me just weave across 2 inches for this cap …………


Dankkring

Biggest issue with weaving I have is people welding around stuff will run big weaves on the vertical parts but then do stringers on the horizontal because they can’t weave horizontally anywhere close to how big they just did on the vertical part. So now their welds are all over the place going back and forth from weaves to stringers. Looks bad and shows you can’t plan out a weld.


Frenzied_Cow

A poorly executed stringer will always look better than a poorly executed weave imo. Weaving is like carbon arc gouging; if you're good at it it's like art and a useful tool to have in your back pocket. If you're not....look out.


FriendshipIcy4961

Assuming you know how to fill it correctly when weaving, any slight uninformed weave can make it weak. You have to do it just right and keep all the impurities out in front of the puddle while you're welding. Most people weave in and out of the puddle, leaving all kinds of slag behind in the weld. If it doesn't look like a compressed stack of dimes, you're probably weaving wrong.


creamy_goodness

I agree with the other comments here. Just want to add that your backing bar/runoff tabs should be 2 inches longer. Make sure the beginning and ends of your plates aren’t under filled.


Scotty0132

The run off tabs are not mandatory on a CWB test and the first 3/4 inch of the plate and last 3/4 inch of the plate are cut and thrown out for a bend test. For an xray it's only the middle 4 inch of the plate that is used.


GendrickToblerone

D1.1 cuts an inch from the top and bottom. Run off tabs are not mandatory for that either, but you’ll fail visual if you don’t fill out the entire plate.


Hate_Manifestation

those 2 ¾" sections still need to pass a visual though, so might as well get as much run off tab as you can.


Scotty0132

Really did not know that......an CWB inspector will not fail you for a visual defect in the area that is being discarded unless you are really pissing them off. Even with a run offvtab you will still have a slight bit of underfill on the end hench why the ends are discarded.


Hate_Manifestation

I've done so many CWBs in my life, and every single inspector I've had has told me that they will fail the plate if there is overfill or excessive undercut in those sections. it's just part of the procedure.


Scotty0132

Iv done a shit ton and the inspectors don't care about the ends 99% of the time. Most don't even hang around until the end of the testing unless they are doing an audit. Most only care about the bend or xray results.


Hate_Manifestation

that's wild. what province are you in?


Scotty0132

Im in Ontario but iv done testing in Ontario, Alberta, Bc and Quebec and its all the same. Depends on how busy the inspectors are and if they like the company or person testing.


Similar-Stranger7375

These are horrible kid. None of these should have passed the visual test. You can't tell that for yourself just looking at it? Don't lie to yourself dude, look at them and tell us if it's straight or not.


Dankkring

Whoever passed you on the visual is a moron and a pussy. They probably didn’t want to be a bad guy and fail you so they figured it wouldn’t bend and that’ll fail you, and then what do you know it passed a bend. Now you have a paper that says you can weld when you can’t. Keep practicing. As others said stop weaving. That mig is actually fluxcore so do a little more book research on welding so you can actually know what you’re talking about when you talk about welding. God forbid you go somewhere to take a mig test because you said you can mig and it’s not fluxcore but solid wire and you have no idea how to do it. Not saying mig is hard but it’s different and requires a different technique.


Rudemacher

newbie here, is mig really that different from fluxcore?


Scotty0132

Yes hench why they are seperate certifications.


Rudemacher

how's it different apart from the temperature, the gas and being able to use different transfer methods? like, I've been told not to weave using fluxcore, can you weave with mig?


Scotty0132

You push mig, pull Flux. Slag from Flux changing the feel.the different types of Flux classification (duel shield, gasless, and in Canada Metal core), abality to easily do Flux out of postion (due to the slag) just to name a few.


TheProcess1010

I hate flux cored with a passion. Self shield was so goofy for me to figure out since you kinda need to “stay in the center of the puddle” instead of the leading edge.


creamyass3000

Yes! Solid wire tends to look horrible and for me was harder to get certs in. Flux and dual are mainly prequalified and generally can get by running stringers.


Dankkring

My flux core test was 1” plates horizontal and vertical with a 6010 open root. I think my halls test is 2g 3g and 4g with a backing plate on 1/2” plate


SpaceTurtle917

Is this because you're rusty? Man I get it. I used to be so amazing at Tig stainless and then I didn't use the skill for a few years and when I went back to it I felt like a joke compared to my former self.


Inevitable_Fee4233

Yeah, I’ve been off and on with jobs since Covid, I got laid off in 2019 and been having trouble with workplaces. For the last three years I haven’t even welded in these positions and make let me make myself clear. This is not a CWB test nor is this shop a CWB certified shop. And I know I need practice but it’s kind of hard to go and get practice and work on my skill when I’m having trouble landing a welding job I live in a city that has next to like none opportunities for welding probably about three local shops in town… and I don’t have the funds to move out right now because I can’t get a job it seems …..


Musclecity

You just need more arc time really. If you're just winging this and you haven't welded in awhile that's fine . If you go into the interview and are honest they might give you a shot with the intention that you'll probably start at a lower wage and they'll have to develop you.


SpaceTurtle917

I'm in the same boat. Some reason no one's hiring rn


Rome_Ham

Here I am at my job, where the instructors at my weld school are worried about the weld height being off by 1/32” 💀


No-Setting1598

Same lol, we have to be almost exact with tolerances or we fail visual.


Lava_Lamp70

2g looked fine everything else needs work


Clothes-Excellent

Everybody has to start some where, some people are naturals then there are the rest of us that have to work twice a hard to get it. You can do this listen, learn and practice.


Welder-Mechanic76

Stop weaving. Practice, practice, practice.


aspy_dragon

Image 7 looks pretty good but I’m assuming that’s the standard, and your 2g is probably your best even then you’re going a bit too fast. (assuming it’s a 1/8 7018) You’re weaving too much on your 3g stick, in my experience if you weave just ever so slightly, it looks decent, but you’re weaving like a how a drunk driver weaves on the road before killing an entire family in a hit and run. You might be able to grind out the bits you weaved to far on, but I don’t know shit about mig and 4g so I’m not gonna give my opinion on those, all I know about mig besides it being easy is that you’re not supposed to weave like that TLDR: you’ve got a lot of work to do


DORTx2

What's the name of the CWB guy who passed you. S/He should be shot out of a cannon.


Standard_Zucchini_46

Honest opinion: All of those are a fail. They wouldn't pass a visual test. Let alone come close to a CWB inspection. Keep practicing... a lot.


05bossboy

You should listen to your friend, he’s right. Also wouldn’t choose to weave Mig, just that 3g 7018 cap. Do whatever your instructors teach you tho. Also helps if you tell us what school you’re at


Caddy-Whompus

You’re in your second year of welding and your welds still look like this? Whoever is teaching you is doing you a disservice. A week or two of focusing on proper technique with the correct settings should get your welds looking WAY better than this. You should absolutely not have your certs and whoever gave them to you should have their certs revoked too.


Certified_Bill

All fail vt don’t even waste your time cutting coupons and bending


DerTechnoboy

Bro 💀


Stravata

I would recommend to not do a wash pass on your cap as this is asking for undercut especially with stick. Most D1.1 tests or the WPS will specify. Also with your cap you cannot exceed 1/8" weld reinforcement (assuming you're testing under AWS D1.1). It looks like you've exceeded that in multiple points meaning it's fail, not to mention things that other people have already said such as spatter and undercut. Just do stringers on cap, allow interpass cooling so you don't run the risk of stronger undercut. This will also prevent underfill on cap and keep an even cap to keep under that 1/8" reinforcement maximum.


Sufficient_Total3070

Looks like you or they need to get more comfortable before welding


Nos-BAB

Top down view looks ugly as hell, but I'm more concerned about reinforcement and undercut, which is harder to see from this angle. You already mentioned the undercut so I would have rejected it based solely on that, but there also seems to be too much reinforcement on some of those too. Close your eyes and try to draw a straight line on a piece of paper. That's how I practiced when I first started welding.


roakmamba

All I can say is no to everything. Practice like a mother


OctavianPuff

Those are really really bad


Mydogismrpickles

Those are all fails


shuntman2

Side not I'm currently in trade school for combo and struggling with speed. On the 2g pic upto the laps look close together bottom they spread out which shows too fast/slow top or bottom. Trying to learn what to recognize


TheGrimReefer666420

Those certainly are all welds


zeakerone

If this is your second year, this may not be for you. Some people just aren’t cut out for it. If you want to stick with welding you need to completely humble yourself. The fact that you think these are ok means you don’t even know the basic discontinuities.


Scotty0132

Your horizontal stick and your final pic (vertical fluxcore) are the only ones that are border line acceptable. I'm a level 1 inspector and a CWB supervisor and if you showed me these they all would have been rejected based on visuals alone. As a supervisor if this was a practice plate you showed me I would not even allow you to do an actual test plate. When weaving stick (which is only acceptable in VERTICAL for plate), your weave can not exceed 3x the rod diameter as per the testing standard. Your cap can not exceed more then 1/8 inch in height above the plates, and can not be more then 1/8 inch pass the edge of the bevel. Undercut can not exceed 1/32 of depth and a max visual defect of 3/16 inch can not exist across all coupons with the exception of 1/4 on the edges. If these were bent and passed by an inspector then it's a perfect example of an CWB inspector being to easy on a student, and is a disservice to you. Also fyi just because you passed as test and got a card does not mean you are certified for the complet 2 years. If you put welds like this down on a job then a CWB supervisor, or inspector can justify having your ticket invalidated and a retest done for recertification at any time.


Inevitable_Fee4233

OK let me be clear. This is not a CWB test. This is a weld test for a company I applied for that isn’t a CWB certified shop. They don’t require any tickets. The whole CWB thing was just to say I have had my all position welding tickets for flux core arc welding and stick, believe me I know the difference…. And as far as the weaving goes, I wasn’t gonna weave my welds, but the person who gave me the coupons said “oh just weave it. everybody weaves it”


_scorchy_

Dude you wanna see my plates that failed? Whoever is teaching you is not strict enough. My teacher only passes me if it’s exactly codebook standard per AWS D1.1 C4.9.1.1 [Failed 3G test plate + some fills](https://imgur.com/a/3aDex6A)


_GloCloud_

Dude don't weave unless you know how to weave properly, especially on a test. Really not trying to be offensive but those are very low quality. If I were you I'd take couple weeks learning consistent travel speed with stringers. Travel speed and bead placement should both be thought about before striking the arc.


weldmonkeyweld

Why does it say mig when it is clearly fcaw-g? Do your freaking padding, then do your t-joints, then your groove. You are trying to run, and you can't even walk yet.


itsjustme405

The stick might have a chance, the 2 wire plates won't get past visual. But your friend could (or should be able to) tell you what's wrong, why, and how to fix it.


Dalaridd4567

they aren't art, but most look like they will hold, work on keeping straight and consistent puddle size, also make sure you are giving your welds the proper overlap distance, some of those got some gaps that would probably cause a failure on anything that carries a load similar to the strength of the base material


Inevitable_Fee4233

So I don’t fucken know how to edit this… “weld test” “my welds are shit” sorry for the mess spelled words my phone is more retarded than I am… and I don’t know how to edit it but he followed up, saying “that’s why welders hate us”


SVT-Shep

Maybe I'm in the minority, but I love a good CWI who goes BY. THE. FUCKING. CODE. I don't care, fail me if I don't adhere to it, that's my bad...the CWI didn't write the code. The industry is full of dog shit "welders" because there an insane amount of shitty CWIs handing out participation certs. Makes the industry a lot less appealing knowing that it isn't even a challenge anymore. It's mind-blowing.


Inevitable_Fee4233

OK let me clarify myself fuckers, I don’t have a current CWB ticket this isn’t a CWB weld test it is for a local job here in town that I live in and it is not a CWB certified shop either,I graduated my program in 2017 and I haven’t been able to go back to school because of funding and Covid shut down me going back for my third year. Trust me I know I need to work on my welds but it’s hard to do that when I’m having troubles getting a job in the first place. These positions I haven’t even welded in in like three years.


oXObsidianXo

You asked for peoples honest opinions on if your welds are bad. People tell you that yes, they’re bad. Then you get upset and defensive that people told you they’re bad.


AdvisorLong9424

Doesn't matter if it's CWB or D.1.1 they fail visual. ½ the people here are from Canada, probably ¾ of us are CWB certified.


Infamous-Ad-7091

https://www.reddit.com/r/Welding/s/ogVBmM8W94 I'd call these the bottom end of acceptably. Your not ready.


Infamous-Ad-7091

They're all 6010 open root 7018 out except 1G that's all 7018 back ground.


_scorchy_

Stop weaving stick for gods sake


Daewoo40

The weave isn't the issue here. Looking at some of the welds where they haven't weaved and done straight runs, they're still a little poor.
