You can use Set.addAll method. s1 is a set s2 is a set then take s3 and try s3.addall(s1) and s3.addAll(s2).

 

Example: 

set<string> myString =
   new Set<String>{'a', 'b'};
set<string> sString =
   new Set<String>{'c'};
set<string> s1= new Set<String>();
s1.addall(myString);
s1.addAll(sString);

 

System.Debug(s1);

 

Hope that helps..
