How to weld aluminum parts with electric soldering iron
Use ordinary 75w or 100w electric soldering iron. Solder and rosin welding small and medium-sized aluminum parts is completely possible. Its requirements are "three excesses"; one is large rosin, that is, more clean rosin is placed on the solder joints; = one is large tin, that is, on the solder joints
Add more solder, and the third is to rub it, that is, to rub the tip of the soldering iron that is full of tin on the solder joint quickly.
wipe. The temperature of the soldering iron tip must be too high, because aluminum is easily oxidized, if you use melted rosin
Separate oxygen and aluminum, destroy the oxide layer on the surface of aluminum parts when the tip of the soldering iron is quickly rubbed, tin
It will then adhere to the surface of the lead parts.
