I assume you mean creating threads on a pipe? Nope.

The line on the left is the main water coming into the house, 3/4 inch what looks like copper covered in tar. Union is 1 inch galvanized, coming off 1 1/2 inch PVC that is gravity fed spring water. Their is a small drip leak happening where copper comes through the foundation. Was going to take it back to inside the house and sweat a new coupler to new copper going out. Any suggestions on fixing the galvanized portions or pointers I may need for the copper bits?
