Shame on you
Yes, the 188 was welded stainless and as you said, manufacturing was a pain. I didn't work on that aircraft myself, but one reported episode in the flight test programme is worth a digression off topic. Dialogue (maybe that should be monologue) between aircraft and FT control:
t = 0
Godfrey Auty (test pilot): "Mach ... port engine flamed out"
Silence from ground
t = 10secs
G.A.: "Mach .... starboard engine flamed out"
Silence from ground
t= 15 secs
G.A. "Well for Chrissake say something, even if it's only goodbye!"
Luckily the restart drills worked
After those AICU problems the boss came to see me (I was running the S&C section at the time) and said "Your blokes are doing dynamic simulation of aircraft response (on ANALOGUE computers!), do you think they could simulate the 188 intake control system?". To which of course there is only one answer possible, but that is how the two aerodynamicists who did most of the pioneering work on the Concorde AICU came to work together - Derek Morriss from the 188 project and Terry Brown from the S&C group. And boy were we lucky to have that combination
For the record, if my memory serves, the simulation showed that the 188 problem was hysteresis in the mechanical part of the 188 AICU.
