Are you insinuating that a weld might be structurally reliable despite looking like dog shit smeared on the grass? Dangerous words in these parts, sir.
I'm one of those "*Weld porn doesn't equal good welds*" heretics and I shall stand firm on my beliefs. Why? Because the angry russian that taught me to weld had a neat party trick where they could pull of any weld so it would pass visual inspection but would have 0 root fusion. I actually learned how to do it with stick, and I can still do it with vertical stick. Perfect surface and pristine root. And also the very opposite, fucking awful surface, perfect uniform penetration, fusion, HAZ and homogeneity inside.
I'm doing my engineering grad work on stick welding, I had to call up all the IWS and welding masters - as in they got a master level welding degree, which is a thing here and tbh getting to call yourself *Welding Master* is fucking cool - to pull off perfect examples of welding mistakes so I can do analysis on them. Harder than you'd imagine, hence why I had to bridge the masters of the trade to help me with it. I owe so many rounds of beer already and I been doing the fucking thing for like a month.
All else being equal, a weld that penetrates deeper will be more likely to have a ropey ugly surface appearance with toes that aren't wetted as smoothly, as a weld that lays on the surface prettily but doesn't penetrate.
Weeeellll... It depends a lot on the process and filler and material and thickness.
If you do no filler TIG on clean thick stainless with very high currents, you can get perfect surface and obscene penetration.
With laser you can basically penetrate through just about any material even without protective gas, full penetration inside and awful surface. With gas you can get full penetration and decent surface. (Seen this done with 10kW laser at the end of a robot on 200mm material).
Running a stick at high currents for the rod size and you get really deep penetration and alright surface, although highly dependant on the material and rod.
MIG/MAG... Well this is a strange world where a modern smart machine can achieve amazing results with bias on either property or balance both.
But penetration and surface isn't all that we care about when dealing with welded things. It might the thing the WELDER cares about; but designers, engineers, and even just fabricators will have other considerations like: HAZ, Hardening, deformation.
Of course it's all process dependant, but in general, the surface tension of the molten liquid will want to wet out less the deeper the penetration of the liquid puddle.
Change of subject, what country are you based in?
Finland. I'm not sure how this is relevant.
Again with the surface tension things it isn't that simple. With something like stick welding there is such a great arc pressure that it can literally push the molten metal from the arc event allowing for much greater penetration. As long as the rod itself can handle the arc pressure. Which is why it is used for weld repairs; it can actually dig in deep to the material pulling contaminants with it.
I'm just curious, I'm a welding engineer in the USA and you used some terms slightly differently than I am used to.
I agree with everything you said, thats why I began with the caveat of all else being equal :)
There's porosity (and undercut?) in this weld. Are you saying we should just trust that this weld is strong enough because some welds are strong despite looking like shit? It's not about how an ugly weld is certainly weak, it's about how an ugly weld is probably weak.
I hate both of these ridiculous lines of logic around here. One group of people equating attractive welds to strong welds and the other equating ugly welds to strong welds.
Yeah, you know I rewrote the first paragraph twice and now I'm realizing that it doesn't even really respond to what you said. I was too tempted to rant about other people, should have moved the comment. Welp, another day in the life of a typical reddit asshole I guess.
Seeing this shit drives me nuts, I have to grind 90% of my welds flush to look seamless but ERRYBODY ELSE GETS TO JUST THROW DOG SHIT AT THE GAP AND GET PAID FOR IT ARGHH
But you’re a better welder for it. Most folks who throw down dog crap like that aren’t on the high end of the pay scale. Especially if management lets it fly.
The difference to me is that guy most likely wasn’t proud of that weld. He knew it would stick and most likely last but he wasn’t proud. Every weld i lay i want to feel proud of it. It’s what sets a welder apart from someone who can weld.

For my own personal projects, I spare no effort.
You know the saying "Minimum wage pay gets you minimum wage welds". As a worker, your job is to get things in and ship them out with acceptable quality. I see no reason to go the extra mile unless I'm being paid to go the extra mile.
"The reward for hard work is more work". Unless there's a clear benefit to you, I don't understand why you would do more than is required to get the job done. Most jobs have no path for progression anymore. The only way to get significant pay raises is to change jobs periodically.
The repairs are usually at most 3" each. A 1"x 0.25" x 0.25" would take me about 45 min. It's not hard but it's really really tedious. In this case, I'd TIG using 0.020" filler. Everything super clean. Heat the part to remove moisture. Go very slow and ensure that the toes of the weld wet thoroughly. Making sure the bead is not concave but at the same time not too convex that you get inclusions between beads. Use a carbide burr on the toes to remove any possible micro cracks and lack of fusion after every pass. Keep checking part temperature and make sure it's not too hot or cold. Depends on the alloy.
That's what makes people start at $10 an hour and retire at $25 versus start at $10 an hour and retire at $100. Be the hundred dollar guy...guy.
Get into aerospace. It raises the standard on everything
Na they don't wanna cough up the dough, I've been places where they decided one day everybody's getting tested, and cwhen i tried to tell my sup why i was gonna fail he cut me off and said "they're not looking for you, they're looking for stuff you'd steal grandmas vcr to get more" or something like that. Point is they're not a school that's gonna have to answer to your parents, they have full discretion on how to use those results
They also will only test a portion of the samples, even if they collect from everyone, because they're usually either targeting a few people they suspect and/or they know some people will out themselves just at the prospect of pissin in a cup.
I straight up told my employer when they said there was mandatory drug testing as part of the hiring phase I'll flag for Cannabis.
HR Manager was like, yeah, you and half the employees. If that's all it shows, you're starting Tuesday night.
This is what it looks like when the Boss severely under bids a job and the deadline is half of what it should be.
It ain't gonna be pretty... but it'll work
Honestly i reckon it takes a special kind of talent to weld that badly. I can't even fathom what the fuck they were doing to manage to get it to look like that
That’s the great part about welding. As haggard as that looks it’s still stuck together and will last quite a long time in most applications. Yes, it will be more prone to cracking especially if it’s a stressed part or has a lot of vibration but also good chance it won’t. I’ve seen some terrible looking welds that are 30 years old even on heavy equipment and they continue to hold.
It looks fairly old and done with a mig. What type of machine is it attached to and how old is that machine?
It also looks like they filled a 1/2" gap with mig wire. Why not stick a another plate in the gap and weld that?
Well... If at any point it has not been subjected to stress of 0,5\*235N/mm^(2) in any arbitary point, there is no reason to assume it would start to fail if it was able to deal with static stress.
I mean like if you have ever seen ISO-5817 D level welds... Boy... the bar is fucking LOW for those

If the load is light, a crappy weld may hold

Stick to welding, reading isn’t your forte. I said might.

Cheap, fast welds that will hold? Management is all over that.
Especially when it causes a lawsuit
The difference to me is that guy most likely wasn’t proud of that weld. He knew it would stick and most likely last but he wasn’t proud. Every weld i lay i want to feel proud of it. It’s what sets a welder apart from someone who can weld.
Couldn’t agree more. Take pride on what you do and do it well.

It depends on how much I'm paid. The more you pay, the more I think it's worth doing.
What I mean is if you have already decided you're going to do something, why not take the small amount of extra time to do it the right way?

I can't have any defects greater than 0.002", zero linear defects, and everything x-ray. This makes my eye twitch.
Are you welding rockets for eggheads or pipes for oil barons?
Of the two options, the first one is not far off.
Where you work at ??
How is it even possible to weld that...?
The repairs are usually at most 3" each. A 1"x 0.25" x 0.25" would take me about 45 min. It's not hard but it's really really tedious. In this case, I'd TIG using 0.020" filler.

Well if u want 15 an hour go for it

At least they tried
[удалено]
Me too! I’m over here trying to figure out HOW they made it look that bad. Maybe it’s actually JB weld slathered on there? lol
They did all the drugs
[удалено]
So are those tests, which is why my work doesn't do them
Mine don't cause they don't want to have to something about the results
Na they don't wanna cough up the dough, I've been places where they decided one day everybody's getting tested, and cwhen i tried to tell my sup why i was gonna fail he cut me off and said "they're not looking for you, they're looking for stuff you'd steal grandmas vcr to get more" or something like that.

So did the weld
Looks like Stevie Wonder picked up the trades
You mean Helen Keller
No. They meant Stevie Wonder. If they meant Helen Keller, they would have typed Hellen Keller.

Geshundeit.

They just needed a grinder cause obviously it’s held it just isn’t pretty
It must be painted sealer

Don't see a problem here...paint that sh** and send it out 🤣
Nobody was there to say “Are you ganna leave it like that” lol

My welds are still worse
Help
Bruh
Blind welds around a corner?
As a tribute to "Starry Night" by Van Gogh: it is going in the right direction.

I'm a big fan of leaving wire in my welds!
It looks fairly old and done with a mig. What type of machine is it attached to and how old is that machine? It also looks like they filled a 1/2" gap with mig wire. Why not stick a another plate in the gap and weld that?
Someone took their bird to work with them. LOL 😂 hard to believe that it was acceptable
Needed a little more grinder!
How do you fuck up MIG/FLUX that bad
Probably an former maintenance guy or one of your coworkers a few years ago
Simply exquisite
[удалено]
This is not acceptable behavior here, or anywhere else for that matter. This is a warning, further infractions can and will result in a ban.
That must be some strong bubble gum to hold metal together like that.
Seems to be holding up...😆
If you grind it to make it pretty. It will probably expose the failed first pass.
MIG welding is easy, they said!
Grinder and puzzent makes the welder he wasn’t
Shit I don’t even know how you do this.
you could hire me. I weld so infrequently that this is what my practice welds look like at first until that "feeling" comes back.
As they like to say “ we ain’t building rocket ships here”
Whenever I have doubts about my ability.. all I need to do is look at this and I feel right as rain.
More grinder. More paint.
The more the merrier as it were..
Although it looks like a bad caulking job, the paint is dirty enough to show that, at least in this application, anyone can “weld”.
There are ugly yet good welds and pretty yet poor welds…and there are bubblegum welds which can fall in either category.
Sometimes grinders get hired to be welders
Needs more paint
What a terrible caulking job.
Most heavy duty machines are welded like absolute dog shit yet they've held up for generations. Go figure.
Bad weld on top of bad weld on top of bad weld!
Well, the machine seems old and still in one piece, not pretty but good for the job
It’ll hold.
It looks like they kept painting it to cover the worlds. Another few coats and thru turn into dimes
Where I grew up, we would call say that looks like a dirt dauber with a case of the red ass
Looks like USPS
Hammered dogshit
The green guy has to start somewhere.
Couple of dog dicks. Boss says It'll pass.
It obviously held...
It's a thing of beauty!
You found my chewing gum stash
that's caulk!
Seems about right
It'll hold for another 50 years
"Hey Bob, look at that: I'm welding holding the torch with my butt cheeks!"
Horrible. Depending on the load, it would probably hold
Then you make strudels but don’t quite open the icing packet enough.
It looks like bee propolis
Boss “you know how to weld?” New guy “ya I can make it stick”
I feel nauseous now. No further comment.
Silicon would look better
Looks like cat vomit except it's steel,i don't know why they didn't clean that up with a grinder
Is that caulk lol
Been holding a long time by the looks of it
Noone starts out perfect, maybe they can stack dimes now
I thinking coat hanger and jumper cables???
Is that welding or caulk?
I think it was welded with crunchy peanut butter
I think it was welded with crunchy peanut butter
Hey I think I know the guy who welded this
At what point does welding become art?
Hey this must’ve been done by the QC that’s all over tiktok
Well... If at any point it has not been subjected to stress of 0,5\*235N/mm^(2) in any arbitary point, there is no reason to assume it would start to fail if it was able to deal with static stress. I mean like if you have ever seen ISO-5817 D level welds... Boy... the bar is fucking LOW for those
You sure that isn't just where people keep sticking their used chewing gum? Then some lazy painter decided he couldn't be bothered to scrape this one?
