Q:my text says aluminium does not corrode much as a passive aluminium oxide layer is formed on it.Well other metals such as sodium adn potassium also form oxides. Why dont their oxides prevent further oxidation ?: sodium oxide and potassium oxide are water soluble aluminium oxide is not water soluble. the layer formed of oxide on the aluminium surface is coherent and adherent with no pores and stuck to the metal surface. the layer is also passive to most acids and alkalies except HCl and anti passive ions if present. sodium oxide and potassium oxide dissolve in any aqueous medium forming the corresponding alkalies NaOH and KOH leaving the fresh metal surface exposed to more corrosion. also the reaction of Na and K with aqueous media like water and acids is quite vigorous and fast unlike aluminium which is mu less reactive

Q:I know when you stick weld aluminum you're more brazing than actually welding but i was just wondering about this, i want some electrodes just in case i need a temporary repair. Also what Amperage should i run it at,and what polarity?? my friend told me to run hotter than usual but hes only 14, and I dont know how reliable he is. Im 14 by the way also and have been welding for two years now and im always out running around the ranch doing small repairs. thanks ahead of time!: Aluminum will oxidize quickly when it is heated in the air. You must have an inert gas around the weld when you are working it. A wire feed or T I G system is better than a stick machine. I suggest you do a lot of reading about aluminum and how to it is welded before you buy any tools. For small repairs that do not require much strength J B Weld will work.
