Flux by flux instructions first before using the provisions of baking, this drying process specification is based on testing and test control obtained, quality assurance of accurate data, which is a corporate standard, different companies have different requirements of the specification, followed by according to JB4709-2000 <<steel pressure vessel Welding Wires Manufacturers procedures>> recommended drying temperature and hold time flux. General flux drying, stacking height of not more than 5cm., Brazing Alloys libraries often number in a dry small to multi-generation, on the thickness of the stacked thin to thick-generation, which should be strictly managed to ensure the flux of drying quality. Avoid stacking thickness is too thick, by extending the drying time to ensure that flux through baking.
