What Diameter and How Deep?

I'm going to be doing a pin and weld job on a 11 1/2" barrel and a 5 1/2" flash hider for the first time and need to know what diameter I should use for the pin and how deep must it enter the barrel? Is a high speed or cobalt pin okay for this or should I use something else? Should a crush ring be used?
