Tech Tip: How to Save Your Aluminum Wire

Proper storage of aluminum wire when not in use is key to extending its lifespan and ensuring high-quality welds.

Aluminum oxidizes rapidly, which can lead to weld quality issues and weaken repairs.

Aluminum Wire and Oxidation: Why Proper Storage Matters

When oxidation forms on aluminum wire, it disrupts the arc, making it nearly impossible to maintain a stable weld.

NO MATTER HOW LITTLE IT HAS BEEN USED

Although aluminum is becoming more common in production, aluminum welding may not be as frequent as steel welding in some shops. Proper wire storage is crucial when not in use, as aluminum oxidizes rapidly, leading to weld quality issues and compromising the strength of repairs.

This is often an afterthought in the shop, with blame falling on the welder rather than considering the condition of the wire.

Proper Storage When Not in Use

To maintain the integrity of aluminum welding wire, we recommend the following:

• Remove the wire from the welder and torch.
• Store it in a ziplock freezer bag or wrap it in cellophane—similar to how a new spool is packaged—for the best protection against oxidation.

By taking these simple precautions, you can extend the life of your aluminum wire and ensure consistently high-quality welds.

Proper storage of welding wire reduces oxidation, resulting in better weld quality, a lower risk of contamination, and increased wire longevity.
