Welding Aluminium Mig Or Tig. The two-handed welding process is the most rewarding method to master as it. Again choosing the correct TIG welding machine is vital.
Aluminum with MIG Welding. Tig welding is more of a manual process and is similar in welding steel using the oxy acetylene method where using a filler rod applied to molten metal in assisting to fuse two components together. A MIG weld is the more straightforward and cheaper of the two welding methods.
Aesthetics are not harmful to steel.
Welding aluminum requires top of the line heat control to prevent burn-through because aluminum tends to retain heat. TIG welds are better for thinner metals and smaller projects because they produce precise and clean welds. The desired thickness of the metal and the joint required are the two main factors determining which of the two welding methods to apply. The Basics of Welding Aluminum Using a MIG Gun To safely weld aluminum its best to go with a minimum thickness of 14 ga-18ga.
