Tips for using explosion-proof impact wrenches to disassemble corroded nuts
1) Remove the nuts with less severe corrosion. First, use a tapping wrench to tap around the nut, and then drop some oil on the bolt and nut. After a period of time, use a tapping wrench to turn the nut clockwise, forcing the rust on it to fall off, and then turn the nut counterclockwise. Repeat two or three times, usually to remove the rust on the nut. 2) Remove the severely corroded nut. The method is basically the same as 1), except that there is no oil dripping on the bolts and nuts, but a "soaking" method is used. The soaking time is several hours, during which the nut is occasionally tapped with a tap wrench. 3) If the above methods are ineffective or urgent to disassemble, local heating can be applied to bolts and nuts using heat sources such as acetylene welding or spray lamps, forcing the oxide skin at the corroded area to peel off. The coefficient of thermal expansion of nuts is larger than that of bolts. When the nut is heated to a dark red color, use an impact wrench to unscrew it while it is hot, so that the severely corroded nut can be unscrewed for a longer period of time.
