Can aluminum tubes and aluminum sheet be oxidized when in the welding?
So why in the time usually required aluminum welding surface-treated by physical or chemical means, that is, removing the oxide film. However, the use of brazing welding, when some special welding material itself joined the special oxidation polymer additive now makes the welding operation easy.
Brass, aluminum welding when it is oxidized certainly exist, generally avoid oxidation pathway is add put oxidants, such as solder paste. You are also exposed to the presence of naturally oxidized in air, an oxide film formed when welding difficult to melt.
