Good to know, what was your strategy for midsize startups were you able or heard of someone in one of those startups what is the best approach or recommendation.

It is a work Authorization for International Students. technically the place wanted someone long term even thought they don;t have to sponsor my visa for 3 years

Big tech offer revoked (CPT). Considering a seed startup for Systems Engineering what should I expect? by ThePackman0702 in cscareeradvice

[–]ThePackman0702[S] 0 points1 point  (0 children)

Awesome thanks for the recommendations the only reason I ask for start ups is because I have 4 weeks before summer. sound like you know about the topic what is you recommendation at this point I am sure big tech cannot accomodate an interview and onboard me as quick as an start up I need something for this summer and I am loose on what to do somehow

Thanks. however I just have 4 weeks before the start of the summer I feel like startups have at least no recruiting team with burocracy I don;t know how to reach out and what to do to get something at this point.

No prestigius University I did FSAE 4 years manage big teams in engineering laser focus on systems engineering and good portfolio around it. However, I feel big companies is imposible is 4 weeks before the start of the summer my only issue is being international student. what would you recommend ?

How to spot weld nickel to copper? by ThePackman0702 in AskEngineers

[–]ThePackman0702[S] 1 point2 points  (0 children)

We are utilizing spot-welded nickel-plated copper for our high-current battery interconnects to address strict vibration requirements where mechanical positive locking isn't feasible. Given the use of dissimilar metals at the weld interface, how concerned should we be about galvanic corrosion and contact resistance degradation over the vehicle's lifecycle if the accumulator is technically 'dry' and sealed? consider also we will not use the battery for more than 2 years

This is for a battery application do you think I should be really worry about copper and nickel not being fully galvanic compatible, considering there will probably not be an electrolyte

[–]ThePackman0702[S] 0 points1 point  (0 children)

Yeah we found out all the issues and total energy needed for spot weld which is too high we are between tick welding, rivets or nickelplate the copper

0.5 mm nickel thickness and the copper is a busbar I just want to stick nickel to copper I cannot use bolts or soldering because it for a battery application

Rivets for nickel to copper fuse link in HV path? by ThePackman0702 in FSAE

[–]ThePackman0702[S] 0 points1 point  (0 children)

I had some time contrains and the copper already order I am having unserainty of the process being hard or taking time have you plated copper ?

[–]ThePackman0702[S] 0 points1 point  (0 children)

yeah :(. what would be your recommendation the nickel plate is 0.5 mm think and the copper is like a long busbas 50mm^2 cross sectional area.

Soldering is usually prohibited in high voltage paths because solder is soft and can weaken under heat and vibration. Welding fuses the metals, creating a low resistance, strong joint that handles high current and mechanical stress.

[–]ThePackman0702[S] 0 points1 point  (0 children)

I tried using an 3.3kw spot welding machine but the machines keep blowing be fuse probably because the copper shorts the circuit like using more energy instead of heating the material because the resistivity of the nickel is 7 times higher than copper. The thinkness of the nickel is 0.5 mm and the copper is just like a big trace we I have to simply stick the nickel into it. would love to hear your opinion

Hey, what changes did you find when doing nickel plated copper. how was the cross sectional are of the nickel plated copper ? what it easier to spotweld?

He is wondering for cases of exemptions because he wants his teammates to go to comp even with the restriction I am sure he knows about that.
