An insight into welding Aluminum using TIG welding
Aluminum is generally a low density metallic substance. It is also a very good conductor of heat and electricity. Owing to its versatile and comprehensive characteristics, aluminum is widely used in several applications and fields. However, the true potential and benefits of using aluminum for manufacturing purposes can be achieved only when aluminum is combined with other metals to form alloys.
There are several ways to weld aluminum at present in the welding industry. However, the most suitable and best practical method to weld aluminum is to make use of (Tungsten Inert Gas) TIG welding technique. Considering the fact that most rudimentary TIG welders are highly expensive, you might be tempted to make use of other techniques for welding aluminum. However, TIG welder guarantees high efficient results, safer experience, easy to install and use method, and hence serves to be as the most efficient tool, especially for welding aluminum. See to that, you make use of argon gas which is totally inert. Also you cannot use the gas tank employed by MIG welder in TIG welding.
TIG welder also provides higher amperage which is essential for greater thickness metals to be welded properly. Always make sure to clean the aluminum metal that needs to be welded before starting with the welding process. Failing to do so, aluminum reacts with oxygen to form aluminum oxide which acts as a protective blanket hampering your welding process. Hence it is quite essential that you clean your aluminum metal pieces before working upon it. Clean the metal pieces with stainless steel brush meant specifically for aluminum metal and then wipe it down with acetone preferably or lacquer thinner. Now you are ready to weld aluminum using TIG welder.
