Preguntar is to ask a question.. and Pedir is "asking" in the sense of requesting or ordering something ...
for example ..
Pregunté a la camarera el nombre y despues pedí un café.
I asked the waiteress her name and later asked her (ordered) for a coffee..
My understanding is that preguntar is specifically about questions (la pregunta = question), while pedir has a wider meaning that could include "demand", "order", "beg" and so on.
Ask him if he will join us for dinner. - this will require "preguntar" and corresponds to something like "John, will you join us?"
Ask him to join us for dinner. - this will require "pedir" (or other options but not "preguntar") and corresponds to something like "John, please join us."
