Welding Aluminum Mig. You should adjust the settings and use wires with low crack sensitivity to minimize porosity cracking and other defects. While performing if your MIG welder has any issue you can try to use lubricants for troubleshooting.
The advantages and disadvantages of aluminum MIG Welding. Like TIG welding MIG welding technique also comes with benefits and drawbacks. MIG welding aluminum relies heavily on having the right equipment due to the soft nature of the welding electrode wire.
This process is a very smooth transfer of molten metal droplets from the end of the electrode to the molten pool.
The droplets crossing the arc are smaller in diameter than the electrode. The complete line of aluminum MIG equipment covers full process capability and amperage range. Fortunately the oxide layer protects the aluminium from further corrosion and thats why it lasts so well. The process will require more heat than mild steel which is the most common metal used in MIG welding jobs.
