Welding Wisdom for Professionals and Beginners Alike.

No, you cannot weld aluminum oxide because it is not a metal. Its melting point is higher than a typical welding torch can reach. Before welding aluminum, remove the oxide…

TIG welding aluminum penetration is the depth the weld reaches in the base metal. To achieve the best results, set the correct amperage, adjust AC frequency and balance, and prepare…

When TIG welding aluminum, the oxide layer may not dissolve due to incorrect polarity. This can cause contamination. Always use alternating current (AC) for aluminum welding. Adjusting your settings improves…

TIG welding aluminum square tubing requires careful control for quality welds. Use 6061-T6 aluminum with a 1/8” wall thickness. Clean surfaces improve adhesion. Set the right current to avoid tungsten…

The “stack of dimes” in TIG welding aluminum is a neat bead pattern that looks like stacked coins. To achieve this, you need to master heat control and filler rod…

To TIG weld an aluminum tee joint, first clean the surfaces with a stainless steel wire brush and acetone. Use 5356 filler metal for a bright finish. Set your amperage…

Stick welding aluminum needs special techniques. Start with Direct Current Electrode Positive (DCEP) for polarity. Preheat the aluminum and clean the surface to remove oxide. Use a push-pull wire feed…

Soldering and welding are different ways to join aluminum. Welding creates a strong, durable bond suitable for load-bearing structures by melting the aluminum. Soldering uses a filler metal, resulting in…

Black soot forms during aluminum welding when magnesium vaporizes from the arc heat and reacts with oxides. To minimize soot, maintain a gun push angle of about 15 degrees. This…
