2. 4043 aluminium alloy - Wikipedia

   en.wikipedia.org/wiki/4043_aluminium_alloy

   4043 aluminium alloy [1] [2] [3] is a wrought aluminium alloy with good corrosion resistance typically used as filler material [4] [5] for welding of aluminium parts. It contains high amounts of silicon (between 4.5 and 6%) and trace amounts of other metals. [6] It is grey in appearance and is sold as either welding wire or welding rod for TIG ...

   For DC welding, the electrode can be connected to the machine's positive terminal (DCEP) or negative terminal (DCEN), changing the current's direction. The process and type of electrode used will typically determine the current. [44] [45] Shielding gas prevents oxygen in the atmosphere from entering the molten weld pool.

6. Aluminium joining - Wikipedia

   en.wikipedia.org/wiki/Aluminium_joining

   Most aluminium alloys can be joined by welding together; however, certain aircraft-grade aluminium and other special alloys are unweldable using conventional methods. Aluminium is commonly welded with gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). Due to aluminium's oxide layer, a positive polarity is needed to break up the ...
