The Effect of ER4043 and ER5356 Filler Metal on Welded Al 7075 by Metal Inert Gas Welding

Al 7075 is widely used in the automobile and aviation industry due to its light weight, strength, and good durability. Fusion welding such as metal inert gas (MIG) is commonly used in joining aluminium alloys. It was used because of its low cost and is generally used by welders. However, defects usu...
