Welding Wisdom for Professionals and Beginners Alike.

Aluminum welding with a propane torch is weaker than using traditional methods. Propane is suitable for heating or brazing, but not ideal for welding. Aluminum melts around 1200°F, and using…

To prevent aluminum from curling during welding, securely tack and clamp the pieces. Weld in sequence to control heat input and minimize distortion. Use the right filler metal and weld…

Laser welding aluminum without cracking requires careful heat control and the use of filler wire made from a more weldable alloy, such as 4047. This method reduces thermal stress and…

Laser welding offers significant advantages for aluminum. It addresses challenges like high thermal conductivity and reflectivity. Using a concentrated laser beam with high energy density, it melts and solidifies aluminum…

For TIG welding aluminum castings, set the amperage to 1 amp for every thousandth of an inch (0.001) of thickness. For instance, a 1/8 inch (0.125) thick piece needs about…

Laser welding of aluminum alloys uses a focused laser beam for quick, clean welds. Aluminum alloys, such as AA 7075-T6, face challenges like high reflectivity and surface oxide layers. Fiber…

Yes, the Lincoln Precision TIG 225 can be loud when welding aluminum. This loud humming sound often comes from high frequency settings. Make sure to clean the aluminum surface and…

To layer aluminum for welding, preheat both filler and base metals to room temperature. Clean surfaces with acetone to eliminate contaminants and oxide layers. Use proper techniques to prevent burning…

To MIG weld aluminum, use Lincoln Electric’s SuperGlaze® aluminum MIG wire. Adjust the voltage and wire speed for ideal spray transfer. Use inert gas, such as argon, to shield the…
