In order to understand welding metallurgy, you need to understand how metals harden.
Carbon and low alloy steels harden differently from stainless, nickel, aluminum, magnesium, titanium, cobalt, and copper alloys.
If you ask 10 engineers what would happen if you heated all the metals above to red hot and then quench them in cold water, you would be very surprised at the answers. Sometimes colleges skip right over this basic stuff.
Normally I send these links out one email a day for Seven days.
But some want to get it all at once. So here you go...
