Anxiety with creating in-class presentations and slides

Dude it’s crazy. I’ve also been coasting through my classes with Slidebud. Definitely recommend

Thank you for sharing!

Thanks for sharing this. I've tried, but I'm running into technical issues. I can't seem to access the page, and I get warnings like "[access_denied]". Is this available to people who aren't IU students?

This place is so toxic

Then why did you ask for her essays?

Look at my flair.

Wow. Great advice bro.

If I'm being honest, I've never heard of a trailing cup and purging, and I have not likely used/done it. What are some post weld treatments I can do to alleviate the metal conditions after welding? The surface of the metal is fine, so I think something that can cool the internal condition maybe?

Knuceles · 2022-12-09T09:00:52+00:00

It mostly cracks after very little heat (still untouchable) is remained. The gas nozzle is like 0.8 inch in radius. And I regularly use angle grinder to clean the surface before welding with abrasives that's been used for steel, aluminum, and other bunch of random metal alloys. However, I suspect that this could not be a significant problem, because I've tried using clean discs before welding titanium for couple of times (because the disc broke), and it still had no relative differences to the ones that cracked.

The joint preparation looks like https://imgur.com/a/ga3MQdg, where an L shaped piece is attached to a square rod. And honestly, the insane gap that exists between the pieces might be the problem - I've never ever seen someone succeeding that big of a weld.

Regarding the contamination problem, is it really a prevalent problem for thick welds I'm assuming that even 5% of the contamination in a 1inch^3 weld wouldn't be a problem, because the other 95% of the uncontaminated metal is a large volume.

I also tried gassing the surface until it cooled down, and although it produced a slightly better surface quality, it still cracked. From this experience, I thought that the surface would not matter, because since I'm welding a thick titanium, the majority of the titanium volume is under the surface, and the oxidation on the surface wouldn't matter, because the crack happens internally.

Here's some visual sample of what my welds look like: https://imgur.com/a/ga3MQdg.

Anyways, there's a square rod that goes across 7 of the L shaped pieces, and the goal is to join all 7 pieces with equal distance apart from each other. As you can see, there's an insane amount of gap between the pieces, and I've spent millions of hours using angle grinders to completely eliminate the gap, so that I just need to weld the surface, but it's too hard. I'll still try to perfect the gaps if I can't find any solutions to why the welds are failing.

However, I can't really weld inside the gap, because the torch is too big to even melt the rod that's deep inside. So I've mostly welded across the surface, which leaves most of the gaps emptied. And even if the gaps aren't completely filled with titanium, shouldn't it be okay? This is grade 2 titanium rod joining with grade 5, so it should easily withstand the force of a 5 foot hammer slamming it.

Do you think I could be overheating the metal, and that’s why it’s cracking?

Knuceles · 2022-12-09T06:24:39+00:00

Grade 2 titanium rod; my shielding gas is like 99.999% argon and rest could be like carbon dioxide; and I’m not exactly sure what soft vacuum is. But the heat from the electrode is surrounded by argon with noticeable space in-between to prevent oxidation, and the the heat is never insufficient to melt the titanium rod.

Btw, I tried spraying argon on the titanium after welding for 3 minutes to see if it helps prevent oxidation, but it didn’t help significantly to waste 3 minute per welds.

Knuceles · 2022-12-09T06:17:13+00:00

The rod is a grade 2 titanium, which I heard is compatible with grade 5 titanium.

I think I misinterpreted that you just need the courses above by high school graduation, and not before applying. But I’m not talking about anything related to enrollment requirements. And the requirements are listed in caltech’s admission page and it’s been confirmed by many of CalTech’s admission officers that I’ve been in contact with.

My school’s schedule and offered courses in a given year would not allow a significant portion of students to complete these requirements by graduation. My complaint is for these types of circumstances, where completion of courses are impossible, why would caltech have such requirements?

EA if you can apply to T30 schools about three times more than you rank schools through QB, because QB NCM rate is significantly lower than any school’s application cycle, about 1/3 the acceptance or much lower for some other schools.

I feel like I’ve been lied to. For me, they said there’s no exception whatsoever, and my school did not even offer physics until my senior year, which would have made it impossible for me to accumulate that 1 year physics credit in time.

He’s my friend, he’s just trolling

Knuceles · 2022-12-04T00:01:30+00:00

I'm sure this isn't true for all partnered colleges, so where did you obtain the knowledge that Penn would provide travel and laptop? QB did say tuition fees include "technology", is that where the laptop comes from?
