I'd always include a -type for something like that, otherwise what 
happens is that grep tries to run on some pipe in /dev/ and hangs forever.

find / -name '*' -type f -exec grep -l "welcome here" {} \;

This assumes that the file is of type f=regular file.  For other types 
see the find man page:

     -type c
             File is of type c:

             b      block (buffered) special

             c      character (unbuffered) special

             d      directory

             p      named pipe (FIFO)

             f      regular file

             l      symbolic link

             s      socket
