I aluminium welding, we have a aluminum oxide layer over
the metal surfae, which is genrally formed in free aluminum
surfaces. This oxide ;ayer is not removed by brushing. So
we have to use the cleaning action whichin the welding
process. So during aluminium welding, we use AC power
source, which given sine wave. This cause the breakdown of
oxide layer of aluminium.
And in general arc welding technology, we use DCRP or DCSP
i.e. reverse or straight polarity for welding.
