If you mean an answer when someone thanks you, then the word is de nada, which means from or of nothing, and may be translated as It's nothing, No problem, and You're welcome. If you mean the way of letting someone know that their presence is appreciated, as in the person being welcome in your country or your house, then the word is bem-vinda, to a female; bem-vindas, to a group of females; bem-vindo, to a male; and bem-vindos, to a group of males or to a mixed group of females and males.

De Nada
in brasil, we say BEM VINDO
welcome is Bem vindo if you want to say "hello, how are you" you commonly say "oi, tudo bem?"
Bem-vindo ao Brasil
Bem vindo ao Brasil ( note that in portuguese the word Brazil is with s no z)
thank you: merci you're welcome in Brazil: bienvenue au Brésil, soyez les bienvenus au Brésil
Well, the way you said in the question is a way to say it, but in english. But if meant how to say it in Brazilian language (which is portuguese, by the way).. it's: Bem vindo ao Brasil
Some ways... Hello has a equal on the Brazilian word: Olá And.. Hi has a equal on the Brazilian word: Oi
you say welcome aboard I don't know why but that seems to be the case
welcome = "bem vindo" Btw, people in Brazil speak Portuguse, not brazilian.
How do you say you’re welcome in Apache
