[QUOTE="PSG-1, post: 393063, member: 6937"] Unlike steel, aluminum is what I would consider to be a 'grainy' metal. No matter how nice the weld may appear, magnified cross sections of aluminum welds often look like a sponge. You can also see this where an aluminum weld breaks. Because it's like a sponge, this makes it far more susceptible to corrosion, especially from impurities such as dirt. After all, it begins life as dirt (bauxite) Due to these properties, it is a difficult material to weld if there is any kind of corrosion, as opposed to steel, where you can literally weld rust with a 6011 rod.
