Helium is used as a safer alternative to hydrogen in meteorological balloons and airships, because of its inert properties. Until the discovery of the application of helium in balloons, hydrogen was used, and the high rate of combustivity led to explosions. Hence, helium is preferred. Helium is also used in welding that involves light metals like aluminum and magnesium that would oxidize if exposed to the atmosphere. Yes, helium is used for the voices of cartoon characters, prominent among them being Mickey Mouse and Donald Duck. Helium is a light gas, and hence sound waves travel faster through it. As a result, the actor's voice becomes high-pitched when he breathes.
