This is one of the most interesting questions you could ask about WW2. I'm going to become a little yakky about this question because it is so important.
In the beginning of the war, before Pearl Harbor, America was asleep. She tried to arm both Britain and Russia but the problem was German subs. They destroyed an awful lot of need materials (including weapons). The American public ignored this so Roosevelt's hands were tied.
On the Japanese side, only Admiral Yamamoto opposed waking America up but since the rest of the Admiralty was all for attacking the US, it was Yamamoto who decided that if they were going to do something foolish, then it better Cripple the US for a long time, or at least long enough to find a good supply of Oil.
Then Pearl Harbor came and America woke up. It was decided that with what they knew, America would engage Hitler first.
That turned out to be impossible, so the factories went into production and Rosie the riveter/welder came into being. I think it was 20% of the work force were women and they did learn how to weld and use a riveter.
By the end of the war, America produced enough tonnage of munitions and ships and planes to fight on both fronts. (The Pacific was made up of 3 fronts, and America supplied them all plus Europe). America simply over whelmed her enemies. It is an amazing story, well worth your while to go deeper. Your grandparents and great grandparents will be able to tell you quite a bit if they served or worked in factories.
