Bake-out is a process which is meant to remove contaminants from components so that high vacuum can be achieved in treatment, and to prevent impurities. To remove these unwanted compounds, engineers perform bake-outs at various high temperatures (these can range from 120 degrees Celsius up to 400 degrees Celsius).
The volatile compounds (such as vapor from components, or external particulate matter from humans or the environment) are driven off of the component during the period of heating. The volatile particles are then removed by the vacuum pump.

Hydrogen bakeout is commonly used for materials or processes when hydrogen induced cracking is a concern. Heating the material to a temperature high enough and long enough to allow the trapped hydrogen to escape from the areas where it is trapped in the material.
This is a common process for post welding of chrome moly steels that do not use low hydrogen welding processes or electrodes and heavy weldments.
