Welding Wisdom for Professionals and Beginners Alike.

Welding 6061 aluminum alloy has specific challenges. Use filler metals such as 4043 or 5356 to reduce hot cracking. Preheat the alloy to 150-200°C to enhance weld quality. Proper techniques…

Both 5052 and 6061 aluminum alloys are suitable for welding. 5052 offers better weldability with lower cracking risk, making it easier to use. In contrast, 6061 provides greater strength, ideal…

The AC waveform in aluminum welding alternates between Electrode Positive (EP) and Electrode Negative (EN). EP removes the aluminum oxide layer, providing a clean surface for welding. EN increases penetration…

Black soot during aluminum welding signals contamination. Clean anodized aluminum surfaces before welding. An oxide coating melts at a higher temperature than aluminum, making pooling difficult. Check your machine settings…

Aluminum welding procedures include essential steps. First, clean the base metal to remove oxides. Preheat if necessary. Use MIG (GMAW) or TIG (GTAW) welding methods based on joint geometries. Monitor…

Clean aluminum before welding to ensure quality. Use acetone, a strong organic solvent, for effective removal of oil and grease. Rinse and dry the surfaces after cleaning. Consider alternatives like…

Cyanoacrylate adhesives, often called super glue, are effective for bonding aluminum 7075. For the strongest bond, use a specialized metal bonder like the 170 or 910® variants. These adhesives cure…

AC voltage is crucial for welding aluminum. It cleans the surface during the positive cycle and penetrates deeply during the negative cycle. In TIG welding with argon shielding gas, AC…

For TIG welding aluminum, use 100% Argon gas. Argon is an inert shielding gas that prevents oxidation while welding. A 75/25 argon/carbon dioxide mix is meant for MIG welding, not…
