FAQS
6061 is a versatile alloy known for its good weldability, strength, and corrosion resistance. Compared to alloys like 5356, it generally offers higher strength but can be slightly less corrosion resistant in marine environments. The key is choosing the alloy that best suits the application's specific requirements. We typically recommend 6061 for general structural applications due to its balance of properties.
Porosity is a common issue with aluminum welding. Ensuring a clean base metal, using a proper shielding gas (typically argon), and maintaining a consistent travel speed are crucial. Also, make sure your welding wire is dry and free from contaminants. Preheating the base metal can also help reduce porosity, especially with thicker sections.
Both TIG (GTAW) and MIG (GMAW) are commonly used with 6061 aluminum. TIG offers more precise control and is ideal for intricate welds and thinner materials. MIG is faster and more efficient for larger projects and thicker sections. Pulse welding, available on both TIG and MIG machines, can also help reduce distortion and improve weld quality.
Aluminum wire is hygroscopic, meaning it readily absorbs moisture from the air. Store it in a dry, sealed container, preferably with a desiccant to absorb any remaining moisture. If the wire has been exposed to humidity, it's best to bake it at a low temperature (around 200-250°F) for a few hours to remove the moisture before welding.
For a 1/4" (6.35mm) thick aluminum plate, a 0.040" (1.0mm) diameter wire is a good starting point for MIG welding. For TIG, a 1/16" (1.6mm) diameter wire is commonly used. However, the optimal diameter can vary depending on the welding process, welding machine settings, and the specific joint design. Always refer to the manufacturer's recommendations.
Finding a reputable supplier is key to ensuring you receive high-quality wire. Look for suppliers with certifications (like ISO 9001) and a strong track record.
