I'm trying to understand the process of integrating different types of iron into a katana. How does a swordsmith integrate hard, medium, and soft iron into the blade? Does it come in during the lamenation process? Do they just put them in during the shaping process? Please help cause I can't find out!

Its done during forging. Lamination is an umbrella term for the structure and process of such multi layered blades. After the smith has forged the sections of the blade, they are forge welded and shaped together. The "folding" occurs separatly for each "steel" or section (If there is only one steel the blade is "Maru-gitae"). Each "steel" is "folded", and then forge welded. I have to use quotation marks because steel and folding are not 100% accurate descriptions of what I am trying to say (for instance, folding is the forge welding of the steel onto itself). Check this site for LOTS of good info: www.ksky.ne.jp/~sumie99/construction.html

Here are some drawings of what the billets of various laminations look like before being forged into a sunobe. Just don't take the text on these too seriously. Its more for visual purposes. Soshugitae would be like putting extra layers around the shihozume billet except for the edge.
