Russians are welding damaged howitzer barrels
Is this actually somewhat effective?

>Is this actually somewhat effective?
yes.

>accuracy
worsens since the gun barrel is obviously affected. they'll need to re-calibrate the gun
>precision
probably not affected that much actually. the welded pieces will always be in the same place so it should be consistent. however the effects of heating and wear and tear will be worsened.
>barrel lifespan
they're doing this to extend the life of the barrel obviously

No but you knew that from the last thread on this topic which is...
Wait.
Anyway, there was a thread, probably by you. I guess you get to repost it since the last one seems to be baleted with prejudice.

I'm more curious about this drone strike on Lviv, what's the factory equipment in this pic?
It's a strike on a civilian warehouse but I can't think of what that piece of machinery is, military or civilian.
What has a gas tank over an enclosure that looks like a 3d resin printer or a kiln or something.
Is it in fact just a kiln of some sort?

Interesting post, to me it does not look military at all. I was wondering why they bombed that as well.
It could have been a random strike to put more pressure into conflict but who knows, really?

Beautiful city, by the way.

I think we're learning something about the vatnik psyche.
Albeit something we already knew.

If you shoot down their aircraft, they like you and think you're strong and friendly.
If you try to negotiate and reason with them, they think you're weak and an enemy.

The more you turn the screws on a vatnik, the more they love you.

Welds are as strong or stronger than the base metal depending on the rod and the material in question. Typical 7018 is good to 70k psi. I don't know what the specs are for Russian artillery though.

It's probably effective at making the shells leave the barrel in a manner that appears normal, which is all that really matters to the crews. If their piece isn't functional then they can't do their job and are likely to be reassigned as meat wave fodder.

I could maybe see it being done to try and make it more useful as a decoy gun. The repair could just look like wear on the external finish from a drone shot, while the hole and associated shadowing would be more visible.

Because welding is not very accurate, there's plenty of distortions due to the heat used in the process.

Also self hardening welding rods are pretty expensive as they are special alloys, and they'll inevitably have drawbacks. Barrels are the ideal part for turning on a lathe so forging/machining is the only manufacturing method that makes sense.

>>64248837
Yuo see Ivan, when you of shooting gun, the welded plug will be of flying out and destroying enemy observer drone!

Also when you are cauldron near Pokrovsk fortress you can be of shootibg at two enemy positions at once! No loss of accuracy compared to usual performance!

The metal next to the weldt will lose its mechanical properties due to change in its Cristal structure due to the high temperatures. It will most probably break again right next to the weldt.

Because while welds are harder, they are also more brittle than the base material.
Also, since you're fucking with the crystaline structure of the metal you are creating points where stress accumulates.
In combination this is really fucking bad for something like a barrel.

As to why we don't just use welds for everything

retards.

the seam is however ductile, elastic, brittle and tough the weld material (electrode, wire, filler rod) is after whatever heat treating process (what you actually did to it, at what settings, how much it heated up, how quickly it cooled down, etc) you applied to it.
>strong
what the fuck does "strong" even mean you illiterate monkeys? there are different parameters to measure - hardness, yield strength, ductility and toughness.
>base material
what the fuck is the base material? if you weld S235 with a MIG wire that has a base yield strength of 355MPa, the seam will have a higher yield strength than the surrounding material. but repeat the exercise on S690 and the result is completely different (if you can even get it to fuse)

The yield strength and ultimate tensile stress of steel varies by a literal order of magnitude depending on the alloying and heat treatment it has received. There is a huge variety of filler rods for TIG welding and wires for MIG welding available, with different material properties.

and I forgot to mention the most important part: welds are not homogeneous. the interfaces between different seams and the interface between the base material and the seam will have different and, in the case of field welds, difficult to predict properties
