I attended a community college 1969 to 1971 and one man you took some night classes worked for the Brunswick Corporation in a local plant that produced warheads and other parts for the defense department. They did a lot of TIG welding in their assembly and he told us that they employed/trained women to provide the welds because they had found women easier to train, plus had the finesse and attention to detail to provide superior welds in a production basis. They just seemed to have the touch.
I would suspect they also could pay them less but I don't remember us asking or him telling us that.
have a good friend, she is a certified welder.
