blessed are you Lord = baruch atah Adonai (בָּרוּךְ אַַתָּה יְיָ)
"What if your Welcome" cannot be translated into Hebrew, because "your welcome" in Hebrew is literally "blessed is he/she who comes" You can say, "what if it happens that you are permitted to enter" = ma yikreh im mutar lekha/lakh lehikanes.
I really hope you mean "blessed feats" and not "blessed feets". Blessed feats = ma'asim bruchim (מעשים ברוכים) Blessed feets = raglayim bruchot (רגליים ברוכות)
The same way all Hebrew-speaking Jews say welcome. It depends on who you are welcoming: said to a male: baruch haba (ברוך הבא) said to a female: brucha haba'a (ברוכה הבאה) said to a group: bruchim haba'im (ברוכים הבאים) It literally means "blessed [is] he/she who comes" or "blessed [are] those who come"
It literally means "the name is blessed", but it's used in the same way as when English speakers say "Thank God."
