Welding Wisdom for Professionals and Beginners Alike.

Welding aluminum is harder than welding steel. Its high thermal conductivity and low melting point create challenges. An oxide layer forms when aluminum contacts air, adding to the difficulty. However,…

For AC TIG welding of aluminum, connect the TIG torch to the positive (+) terminal and the earth lead to the negative (-) terminal. This setup allows for optimal heat…

MIG welding is best for thicker aluminum and larger projects. It is fast and efficient. On the other hand, TIG welding is suited for thinner aluminum. It offers precision and…

To clean aluminum for welding, follow these steps: 1. Remove oil, grease, and moisture with an organic solvent like acetone or strong soap. 2. Use a stainless steel wire brush…

Excessive soot in aluminum welding can indicate problems with the welding technique or setup. While black smut doesn’t always mean a bad weld, it may impact weld quality if ignored….

Welding aluminum is harder than welding steel. Its high thermal conductivity causes quick heat loss. This trait makes meticulous surface preparation crucial to prevent cracking. Despite the challenges, skill development…

When welding aluminum, use alternating current (AC). Aluminum is sensitive to oxidation, which creates a layer of aluminum oxide. This layer makes it hard to start the arc. AC helps…

Preheat 6061-T6 aluminum to 150-200°C before welding. Use filler metals like 4043 or 5356 to avoid cracking. Remember, welding can lower tensile strength. To reduce porosity, apply proper welding techniques….

The best tungsten for aluminum TIG welding is usually 2% lanthanated (blue tip) or 100% tungsten (green tip). Lanthanated tungsten allows for versatile current settings and reduces balling. For 1/8”…
