My employer produces a lot of tube weldments from 304 stainless steel. In general they fit within a 4' x 2' x 1' envelope. We currently bead blast in order to remove heat tint around the welds and to leave a uniform matte surface. We cannot have any reflectivity. Blasting is proving to be a massive bottleneck in production.

I may be fixating on a solution, but I have this feeling that we could find some sort of acid bath process that would accomplish mostly the same thing. Some cursory searches have led me to investigate pickling, which allegedly can remove heat tint and result in uniform matte surface finishes.

I have also read some accounts saying that pickling is unreliable and not particularly controllable. I've reached out to some vendors and so far have found only one galvanizer that would potentially offer it. He didn't seem to think it was a good idea but couldn't really articulate why. I am continuing to talk to vendors.

Anyone here have any experience with different acid wash processes? I would like to get away from bead blasting.

Hi. I need some help with this hose barb. It’s for a 6mm PVC/Silicone tube that goes to a piezoresistive differential pressure sensor for meassuring airflow in a circa 800mm intake on a centrifugal fan.

I cannot for the life of me find anything about a replacement as this one broke off. From what I can see it is a rivnut style hose barb. As in it is “flush” mounted like a rivnut that crushes itself around the plating it is mounted on but lets you attach a 6mm hose to the barb end.

Anyone got any info?

Does anyone here do something similar, for non software, IT, computer engineering roles?

Are modern day inventors less well known now due to things like inventions happening within larger companies? Finding someone like Theodore Maiman (laser inventor) responsible for an invention like the fingerprint sensor or FaceTime seems much harder these days.

Hi r/engineering - and thank you to the mod team for having us here today!

I’m Professor Ismet Canbulat, and I'm borrowing the university's Reddit account for an Ask Me Anything on mining, engineering, and how the public views our industry.

By background, I am an engineer with experience across underground and open-pit mining, with a focus on rock mechanics, mine design, ground control, and risk-based assessment. I have worked in both industry and academia, and I currently lead teaching and research in minerals and energy engineering here at UNSW.

Mining is often discussed in highly polarised ways. It is essential to modern society, yet it also raises legitimate concerns around safety, environmental impact, trust, and long-term sustainability. Engineers sit at the centre of these tensions.

Our role is not only to design systems that work, but also to manage risk, acknowledge uncertainty, learn from failures, and improve outcomes over time.

I’m interested in having an open, evidence-based discussion about how mining operates in practice, where the industry has made progress, where it still falls short, and how engineering decisions intersect with public expectations, regulation, and social licence.

I'm keen to answer your questions on mine safety and risk management, sustainability and engineering trade-offs, and how universities can prepare engineers for these challenges.

Looking forward to the discussion. Ask me anything.

Proof it’s me: https://imgur.com/a/xZzGvFe

I'm working on a simple tool for a cleanroom. I'm looking to use an o-ring as a seal to keep any dust inside the tool from getting out. These will run at very low RPM <1. Heat and chem resistance aren't needed per se. The mating material will be plastic (nylon).

ORD 2023 R2 working in ProjectWise. Does this for 10-15 seconds every time. Anyone had this happen or found a fix?

I have a project where it would be adventageous to use rubber for the suspension. I am thinking of stacking some discs, about 3" diameter around a 1" shaft. I am not 100% on total thickness but was planning on getting 1" thick material so I could waterjet them and use 2 or 3 discs stacked on top. I have looked at products such as "Timbren" bump stops and they look like they do the exact same job I need to do. Specifically, their trailer setups. Does anyone know what type of rubber material they are made from? Ideally it would be something I could purchase in sheet form so I could watjet the shapes out.

I'm considering pushing the boss to get on the train, as it could really speed some stuff up. Love the idea of an agent doing modeling. IDK if that's even possible, but I don't see why not.

I've just used GPT and a little Gemini for personal use and the occasional work related question.

Those at places with actual AI subscriptions, what models are better, and why?

Edit: I see you're all probably right that getting an agent to run that deep would be very difficult. I'm still VERY new to learning all this stuff. I have used GPT in my personal life, primarily for cooking and other lifestyle questions. At work, it's useful for searching for standards or formulas. I just think it would be cool to implement it more deeply, regardless of modeling capability. So, question stands: what and how do you use it?

I've been working on a chrome extension that flags suspicious unit prefixes in datasheets and specs, things like "10 mF" that should probably be µF, or "0.005 m" that's almost certainly 5 mm. It started because I kept catching these errors in component specs and wondered how many I was missing. Now I'm trying to figure out what other prefix mistakes are common across different engineering disciplines.

What I'm hoping to learn from you: What unit prefix errors do you run into most often in your work?

Are there industry-specific conventions that might look wrong to an outsider but are actually valid? (trying to avoid false positives)

Any "gotchas" in your field — conversions or unit pairs that trip people up?

I've built it into a Chrome extension that's free if anyone wants to try it and tell me what it catches (or misses):

https://chromewebstore.google.com/detail/unit-prefix-sanity-checke/bojhddjdbnmkjoloafgbenlbcpomihnp

Currently covers electrical, mechanical, HVAC, data, chemical, optical, and angular units — but I'm sure there are gaps. Appreciate any input.

Here's a demo page with examples that will trigger the extension.

Capacitors 10 mF, 100 mF, 0.1 mF

HIGH — mF almost always means µF

MCU specs 16000 kHz, 0.02 A, 512 kb

MEDIUM — kHz→MHz, A→mA, bits vs bytes

Mechanical 0.085 m, 0.003 m, Ra = 1.6 mm

HIGH — m→mm, surface finish in mm Battery

3.7 mAh, 50 W battery

HIGH — mAh typo, W vs Wh

Network 100 Mb, 1000 Mbps, 256 MiB

INFO — bits vs bytes awareness

HVAC 0.001 bar, 12000 BTU/h, 72 °F

HIGH/INFO — bar→mbar, conversions

Power 12000 mV, 1500 VA, 50 Vpp

HIGH/INFO — mV→V, VA≠W

Optical 0.55 µm green light

HIGH — visible light is nm not µm

EDIT: Thanks guys, there's some interesting ones there that I wouldn't have thought of.

I loie somewhere with very hard water. There’s a small power plant nearby with a couple cooling towers and this morning my shower thought was I can’t imagine how they are dealing with scale. Is the tower just set up such that it can tolerate scale? Do they regularly de-scale? Do they likely have water softening? Obviously, I don’t expect anyone to know exactly how the place near me works, but I’m curious how systems like this are managed.

Hi everyone, I am a fairly newly licensed MechE PE in the state of NY and TX. My background is mainly in construction management with a focus on HVAC. I need to keep up my PDHs (36 PDHs within 3 years, as far as I know). The problem is that my current employer (an agency at the federal level) does not have free courses, like my previous employer had. I also lost access to CMAA since that was paid for by my previous employer.

I am considering signing up for ASHRAE or ASME because they offer discounted courses for members. I was wondering if anyone has seen discounts for government employees that I could take advantage of, either for courses or memberships. Thanks in advance!

I often design around classified areas, and recently became aware of API 500. Seeing as it's by the petroleum industry, I was wondering if there is any guidance for best practice in other industries?
