I don't know of a single time primary adamantium has been damaged. It can be altered at the molecular level, but you aren't going to destroy it by physical means. It's indestructability is its signature and what distinguishes primary and secondary.

Welllll, Hulk did dent Primary Adamantium Ultron is SW (got his leg busted apart due to it, but he did do so). But yes, I agree, Primary Adamantium is about as indestructible as they come.
Superman has also shown the ability to go intangible so he may be ables to vibrate through and damage Ultron's inners. But then again Ultron did beat the shit out of Vision so I dunno.
Heat Vision can damage it on an moleculer level so it's very possible. Adamantium is durable because of it's atomic bonds, severe those bonds and the adamantium loses its durability. I only said that it's a possibility and not a sure fire thing anyway.
All superman has to do is attact the joints the points where ultron has to move knees elbows neck those are not as durable as say his chest because they are bendable
Nope, Vibranium is a harder material than adamantium is. T'Challa anti metal claws have been able to damage vibranium because they seperate the atomic bonds that holds it together. So HV concentrated into a beam can easily do the same thing.
Sorry, I cant do scans, but its a popular event in SW. Its towards the end of the series, #10 maybe, when Hulk slams a small opening into Ultron, allowing Wasp to fly inside him and destroy him from the inside.
Adamantium may have a really, really high melting point... but it is still metal and as such it is a good thermal conductor. In Secret Wars, Human Torch beat Ultron since the robot's internal systems were damaged from the heat. Superman can replicate this feat with his heat vision.
The Human Torch incident is interesting. Certainly if Supes was fighting an Ultron of that level then he could probably win the same way.
The intangibility thing is also interesting. I wonder if beings like Superman and the Flash could do to Ultron what Flash did to Amazo? They are more than just intangibility - they also have that whole vibration thing going...
...in fact I wonder if Superman or more likely Flash could mimic the vibratory effect that causes vibranium to break down adamantium?
As for destroying the atomic bonds, that is also an interesting one. Adamantium for all its durability is still a metal and still seems to have a regular atomic structure which can be broken down by the right application of energy. Supes is kind of unique in having the ability to see atomic bonds combined with the power to target them with a vast amount of heat energy. But I'm not so sure he could do it over any large enough volume to cause real damage.
Otherwise he's just going to have to resort to power and speed to try to get enough hits in to do some internal damage.
I flipped through the entire thing and didn't find it. There is a robot that gets destroyed in the way you're talking about, but it isn't Ultron. Maybe you are misremembering?
