The general response to "thank you" (Danke) is Bitte (which also means "please"). If you want to be emphatic, Bitte schön is idiomatically equivalent to English "You're very welcome."
If you're not familiar with German pronunciation, Bitteis approximately BIT-tuh and schön uses a sound that doesn't really occur in English (SHAIN, as it's sung in the Wayne Newton song Danke Schoen, is a Yiddish dialect version that's considerably different from how it's normally pronounced in standard German). You might want to restrict yourself to just Bitte until you hear how the people you're talking to pronounce the ö sound... which will probably happen right before you need to use it, as "thank you very much" is Danke schön.
"welcome" translates as "willkommen"
