The acid sedimentation tanks in the factory are being upgraded, and there is concern that the sulfonation reaction products on the tank walls may affect the quality of welding. What is the best way to deal with this issue? Is it sufficient to simply grind and remove the rust?

If possible, it’s still best to use sandblasting for thorough rust removal, as it yields good results.
