Alloy 2024 – Poor Weldability
Alloy 2024 – Poor Weldability

For this reason, you will never find a recommended filler metal for welding 7075 or 2024 in any manufacturer’s literature. However, there is one relatively common application in which 7075 is welded with no risk of dire consequences, and that is the repair of molds for injection or blow molding of plastics.

Alloy 3003 – Excellent Weldability
Alloy 3003 – Excellent Weldability

For example, if weldability is most important to your project, but strength is not, it may make sense to choose Alloy 1100, as this aluminum grade has excellent Weldability, but is not typically used for high-strength or high-pressure applications.

Alloy 5052 – Good Weldability
Alloy 5052 – Good Weldability

Tig welding 5052 Aluminum. which filler ? Either filler is good unless you are anodising it then go for 5356. 4043 will be more ductile and less likely to crack but on the other hand 5356 is a stronger material but tends to crack if you don't cap the weld properly.

Alloy 6061 – Good Weldability
Alloy 6061 – Good Weldability

COMMON ALUMINUM PROBLEMS - QUESTIONS AND ANSWERS. QUESTION: I need to weld aluminum base alloy 6061-T6. What filler alloy should I use for welding this base material? This question is characteristic of many that I receive on a regular basis. The base alloy type in the question may vary, but in essence the question remains the same.

Alloy 6063 – Good Weldability
Alloy 6063 – Good Weldability

6063 is the most common alloy used for aluminium extrusion. It allows complex shapes to be formed with very smooth surfaces fit for anodizing and so is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames.

Alloy 6063 Good Weldability
Alloy 6063 Good Weldability

AA 6063 is an aluminium alloy, with magnesium and silicon as the alloying elements. The standard controlling its composition is maintained by The Aluminum Association. It has generally good mechanical properties and is heat treatable and weldable. It is similar to the British aluminium alloy HE9.

Alloy 7075 – Poor Weldability
Alloy 7075 – Poor Weldability

Q: You have discussed previously the fact that some aluminum alloys, such as 7075 and 2024, should not be welded. But I know a fabricator who occasionally welds 7075. Is he engaging in a poor practice, or is there something I don’t understand? A: I can’t really answer your question definitively ...
