Question: 1 / 400

What is the minimum temperature and time required to dry submerged arc welding flux received in damaged packaging before use?

400°F for 1 hour

500°F for 1 hour

The minimum temperature and time required to dry submerged arc welding flux that has been received in damaged packaging is set at 500°F for 1 hour because this level of heat ensures that any moisture absorbed during storage is effectively removed. Maintaining the integrity of the flux is crucial, as moisture can degrade its performance and lead to issues such as porosity in the weld. The specified temperature and time combination is derived from industry practices and safety standards, ensuring optimal performance of the welding process. The choice of 500°F strikes a balance between being hot enough to evaporate moisture without damaging the flux material itself, which could happen at higher temperatures.
