6061 Aluminum welding Tips
Here are some tips to help you weld 6061 aluminum:
- Use a clean, well-ventilated area when welding with humidity control especially when welding with MIG welding. High humidity will cause weld porosity.
- Make sure that your welding equipment is in good condition and that the electrode is the correct size for the job.
- Use a high current setting when welding 6061 aluminum. Choose right welding polarity– DCEN or Pulse for TIG and AC or Pulse for MIG Welding.
- Practice your welding technique on scrap pieces of aluminum before starting your project. This will help you get a feel for how the metal behaves and how best to weld it.

Best filler rod for 6061 aluminum
There are many types of filler rod that can be used for 6061 aluminum. The best type of filler rod to use for this metal is the 4043 rod.
This is because it has a lower melting point than the other types of rod, and it is also less likely to cause porosity in the weld.
The next best type of filler rod to use for 6061 aluminum would be the 5356 rod. This type of filler rod has a higher melting point & weld strength than the 4043.
TIG Welding 6061 aluminum filler rod
If you’re planning on TIG welding 6061 aluminum, you have two main filler rod choices: ER4043 and ER5356.
Both have their pros and cons, so it’s important to know which one is best for your project.
ER4043 is a good all-purpose filler rod with good crack resistant features. It can be used for welding both thin and thick materials, and it produces good looking welds.
However, the welds made with ER4043 has low strength, ductility and poor color match compared to ER5356.
ER5356 filler rod is also the best choice for TIG welding 6061 aluminum. ER5356 gives high strength weld with good ductility and color match.
However, it doesn’t flow as smoothly as ER5356 and can be more difficult to control.
MIG Welding 6061 aluminum
MIG welding 6061 aluminum can be done with either 100% argon or a 75/25 mix of argon and helium.
It is important to use a pure gas (free from moisture & impurities) when welding this particular alloy because it helps to prevent porosity.
MIG Welding 6061 aluminum can be done with two types of welding wire: ER4043 and ER5356. Here are some tips on how to weld this metal effectively.

When MIG welding 6061 aluminum, it’s important to use the right type of welding wire.
ER4043 is a good choice for welding this metal, as it has good corrosion resistance and can be used on a variety of thicknesses. ER5356 is another option that can be used for welding 6061 aluminum.
This type of wire has a higher melting point, which makes it ideal for thicker metals.
To get the best results when MIG welding 6061 aluminum, it’s important to use the right settings on your welder including setting right amperage, polarity and material surface preparation.
The wire feed speed and voltage should be set according to the manufacturer’s instructions.
6061 filler rod
There are a variety of filler rods available on the market for the TIG welding of aluminum.
For example, ER4043 and ER5356 are popular choices for the 6061 alloy. However, which one is the best choice for your application?
ER4043 is a general purpose TIG welding rod that can be used on a variety of aluminum alloys.
It is considered to be an all-purpose rod, as it can be used for both light and heavy gauge work. Additionally, it provides good penetration and has a low melting point.
ER5356 is also a good choice for TIG welding 6061 aluminum. This rod has a higher melting point than ER4043, which makes it ideal for heavier gauge work. Additionally, it provides good weld strength and corrosion resistance.
So, which filler rod should you choose for your 6061 aluminum?
Can aluminum be welded?
Yes, aluminum can be welded, but it is not as easy to weld as other metals.
Aluminum has a lower melting point than other metals, so it is important to use a welding rod that has a lower melting point as well.
Aluminum also oxidizes quickly, so it is important to clean the metal before welding.
