Only in Russia.

Professional welding instructor here, thats what we call a "gorilla weld"! Its not especially pretty but its quite strong, that's at least 6 passes of a wire fed process (either mig or fcaw-g). It looks like that "pipe" doesnt even hold anything up, pretty much just its own weight.

TL; DR its not going anywhere, you guys need to quit your whining. I've seen welds just as poor come from the American automotive and manufacturing industries.

>>30913896
there are only two to three T-72B3M in western military district

A whole lot of good it did them when faced with actual ATGMs outside of testing grounds.

kind of hard to tell under the giant fuckin blob

>>30913972
read what the welding instructor wrote, also this part is fragile anyway and will certainly be destroyed if a tank shell hits it bad welds or not, it really does not matter.

>>30913965
Dude even taking a shit it looks so beautiful and majestic.

>>30913976
How many T-90 kills have there been in Syria so far? Last time I checked there were one or two dubious kills, anything else?

>>30913436
it's a periscope right? Guess they just didn't care too much

>>30913972

This. More weld does not automatically equal more strength. A weld that looks that horrendous has been done improperly, and will most certainly fail under stress.

Source: My dad who welds for a living.

>>30913996
As has been said in the thread already, its a periscope that won't take that much stress to begin with. They likely let someone's son or some new guy try it.

Incidentally this is why Russians have so much trouble with PAKFA
Manufacturing tolerances required for a stealth fighter are on a whole different level than what they are used to.

This is a much better compound bead

>>30913436
This is pretty shit. Clearly a newer guy getting the hang of compound welding and rushing the job, fucking up his heat management on the piece. It'll probably still hold just fine, though, and is easily ground off and rewelded if necessary in a day by a single worker.

Honestly, the specific welds aren't the problem. It's more the fact that they're still doing all this by hand rather than using the cheaper, more advanced and more consistent production methods employed by just about every other major .mil producer.

>>30913644
>>30913606
It doesn't really matter how pretty the weld is for integral joint strength - a perfect bead is not necessary for the joint to still be stronger than the surrounding material.

What, however, IS a problem revolves around the way in which that weld is "ugly". If the welds, just by looking at them, show significant issues with heat management during the process (excessive burn-through or pitting showing too much temp and excessive splatter, globbing or even outright bead lifting showing too little heat penetration), then you've got a problem with joint integrity. The pic here >>30913568 shows significant weld integrity issues along entire beads (whether this is a shitty corrosion repair job or initial production is hard to say). The joint here >>30913436 is generally fine. Not pretty, and with a very half-assed grinding job to knock some of the ugly off, but structurally probably fine.

No, fuck off! The worst production welds Ive ever seen are on early 90's GM trucks. Complete and utter shit.

Trust me, we, as Americans are no further removed from slipping up and making pure shit welds and QC than anyone else. Period.

OP weld is way to hot with major undercut and not tied in

Still looking...

The fact of the matter is that the US tends to make far more extensive use of welding automation in addition to grinding down/smooth/off exposed beads as a matter of course during production. This means you'll rarely see a demonstrably "bad" weld and very few ugly ones on US production military vehicles after the early-mid 90's.

>>30917033
>grinding down/smooth/off exposed beads as a matter of course during production

>>30917086
Just FYI, his farts are like week old death facefucking a volcanic sulfur vent. Try that diet at your own peril.

So why bother hiding/grinding down shitty looking welds?

>>30917157
Less extra weight (adds up a very little, but it does add up)
Actually see if the weld is good (more useful if you can't see the back side for heat pen marks and you're not using X-rays to check like in Sub work)
Doesn't snag clothing and gear during use
Doesn't cut or abrade user hands, pants, backs, elbows, etc.
Aesthetics, especially if you're a subcontractor delivering at certain QC levels

>>30917235
honestly, the only thing you said that really matters is the "see if the weld is good" part, and that isn't controlled using the welders eyes. This isn't the 1940s.

It's more of a professionals' pride than anything, and i suppose it adds workhours to the contractor. The end result is a much nicer product, sure, but it doesn't really matter when the product is used for its intended purpose.

>>30913766

>the only thing you said that really matters is the "see if the weld is good" part
You've never ripped your pants all the way up the leg and put a pretty good gash in your thigh sliding over an unground weld on a hull, I take it.

>and that isn't controlled using the welders eyes.
Any welder who's been on the job for more than a few years can look at a joint and tell you if it's any good in way less time than half the checking gear. The only time we really use that gear on a weld by weld basis is if we're doing NBC/water/air sealed/pressurized container work because fucking NO ONE wants to recheck a mile and a half of bead just to find that one pinhole when the whole thing fails a pressure test.

You ever actually done any metalworking?

Comparison to top notch welding (unpainted of course).

Personally, it just looks like the welder was dicking around wasting some time, probably "looking busy" waiting for quiting time so he doesn't have to start on another unit.

Apples and oranges. The tank is steel, and is welded using actual welding techniques. The picture you posted is aluminum, and is "welded" using friction stir "welding", which is actually a type for forging. They are entirely different products and friction stir takes no human expertise or skill
