importance-of-the-drying-process-for-partsThe drying of parts is an important, frequently underestimated finishing process. In a furnace, temperature ca. 130 °Ctime > 30 minIn a vacuum,temperature ca. 110 °Cvacuum ca. 15 mbHeating in a hot rinsing bath(temperture ca. 80 °C), then air- Welding Hydrogen embrittlement Flaws in EB welding (vacuum)- Penetrant testing less sensitive- Coating Bond strenght and strength properties of elastomers and synthetic resins Influencing coatings in a vacuum (oxidation) or reactive gas Examples of the damaging influence of insufficient drying on the subsequentfinishing processes:During pressure decrease,danger of ice forming onthin cross-sections if the dwell time is too short.Reason: no convection,little radiation Drying processes and their problems: Dwell time too shortTemperature too lowFouling of the water:"water spots"Dwell time too shortTemperature too lowWater remains in hollow spaces,gaps, pores, and cracksToo much time and/or unsuitable storage between drying and the subsequentfinishing processes:- Condensation water- Repeated moistening, e.g. when stored in rain
