The same way all Hebrew-speaking Jews say welcome. It depends on who you are welcoming:
said to a male: baruch haba (ברוך הב×)
said to a female: brucha haba'a (ברוכה הב××”)
said to a group: bruchim haba'im (×‘×¨×•×›×™× ×”×‘××™×)
It literally means "blessed [is] he/she who comes" or "blessed [are] those who come"
Bruchim ha'baim l'knesiya ha rishona Shel yeshu b'Ivrit.
"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.
brukhim haba'im le'amritsar
welcome in Hebrew is "baroch haba" or "shalom" or "brocim habaim"

Well, honey, in Hebrew, you say "mama" by pronouncing it as "ima." It's as simple as that. So, go ahead and impress your friends with your newfound linguistic skills. You're welcome.
