Compared to welding other metals, welding aluminum is easier because of various factors, among them the propensity of aluminum to thaw out at a comparatively lower temperature and not break when it turns rock-solid. Depending on the type of alloy of aluminum you are using, you will work with the metal differently. With a little effort you can learn how to weld aluminum in all its different forms.The various types of alloys include non-heat-treatable alloys like the ones containing manganese (Mn) and Magnesium (Mg) and heat-treatable alloys containing magnesium zinc and silicon copper.Work pieces made from these types of aluminum are easier to work with whereas the ones containing copper and lead are harder to work with. Copper and lead alloys usually have a tendency to crack, which makes it harder to work with them.Different Welding Methods - MIG and TIG WeldingApart from gas and plasma welding, the two most often used welding methods are TIG welding and MIG welding. Tungsten inert gas (TIG) welding, also known as Gas tungsten arc pipe welder(GTAW) uses non-consumable tungsten electrode to produce the weld. The power is a constant current welding power supply.MIG welding process is a subtype of gas metal arc welding. Among the two, MIG welding is the more advanced and can handle thicker aluminum work pieces, at a much faster speed.Safety, Precautions and First AidSafety for yourself and your environment should always be your primary concern when welding aluminum, or any other metal. Welding is unlike many other hobbies or jobs because of the high temperature and stress that are involved in it. Apart from the high temperature, flames, the arc and molten metal are constant risk. Keeping this in mind, wearing your helmet and glasses while you work cannot be compromised with. It must be a habit with you to flick the glass down when you start welding.
