Probably the problem is solved now. But from experience I always find the welds created. Probably because of the vibrations or the excursion ends. I was wondering how they make the pieces For aerospace? Increased vibration and temperature range.
A good question indeed!
The aerospace assemblies that I have examined were all encapsulated with a light weight rigid foam material. Those were designed for single-use rocket-powered devices that did not allow for the possibility of failure. The high-priced avionics in aircraft that I have seen, back before surface mounted components, used components mounted with quite short leads, between well anchored terminal posts. An examination of older military surplus equipment will be very educational regarding how to produce rugged assemblies.

Probably others here can provide photos of how it is done currently.

Rigido foam, yes! I encountered it when I had to remove an EEPROM from a Ford electronic steering box. I have a tool (DIY) that removes it instantly but this wouldn't come off. I finally figured out why.

The "WHY" might be handy for others to know about. I am impressed that you were able to get into the FORD box. My observation of their radios a few years back showed that they were not intended to be repaired.
