Greeting from the frozen midwest, my name is Henry and I was looking on the net for info about refining processes when i came across this site . I'm an auto tech but have always enjoyed working with metal as a hobby,have alot of friends that are welders ,they like shapeing steel and iron . I've wanted to learn about PMs but never seemed to be able to find a good source for information . I think Ive hit the jackpot here . There seems to be a lot of skilled people here ,I eager to learn how to safely work with products used , and proper methods .
