I agree with ya AlanB.
I have held a valid A&P since 89 and worked on DC9, DC10, DC8, B727, B737, B757. Currently B737s.
I have done alot of sheetmetal work on DC9s and quite a bit on B737 in heavy checks, light cks...etc
The only welding on any of these aircraft I know is TIG on titanium ducts and door sill plates on entry door openings and cargo door openings.
The rest of the structural part of the airplane is sheetmetal and composite held together with rivets (soild & cherry), hi loks, hucks, bolts and glue for the composite part.
