Scholom Aleychem on Yom Tov

Sholom Aleichem is not a very old minhag, therefore there were different ways it was done. In general, it usually depends on Kabbolas Shabbos - those who say the complete Kabbolas Shabbos (like in FFDM) also say Sholom Aleichem. Those who do not say Kabbolas Shabbos (and start on Mizmor Shir) - do not say Sholom Aleichem. (Those who say a partial Kabbolas Shabbos can either say or not say Sholom Aleichem).
