La Crosse Pro Welders Share 3 Tips for Aluminum Applications
From aircraft manufacturing to industrial construction, there are several projects that require aluminum welding. Due to its chemical makeup and low melting point, manipulating the material can be difficult. Luckily, the professional welders at C & C Machine, a machine shop based in La Crosse, WI, have a few helpful hints to make the metal fabrication process easier.
3 Welder Tips & Tricks to Follow for Aluminum Projects
1. Use a GMAW Technique to Prevent Material Damage
Aluminum melts at significantly lower temperatures when compared to other materials, which means there’s a good possibility it will distort or burn through when it’s exposed to extreme heat. To prevent material damage, use a GMAW technique. Using a rotating mechanism and low current, the process doesn’t allow aluminum to get hot enough to burn through.
2. Follow Best Practices to Prevent Magnesium Oxide Buildup
When welding aluminum, it’s important to eliminate magnesium oxide buildup on the weld near the material. Otherwise, the aluminum color could change as it cools. Following welder best practices will stop aluminum discoloration after the project. To prevent magnesium oxide buildup, angle the welding gun correctly and user filler materials that protect from oxidation.
3. Choose a Filler Metal With Low Heat Sensitivity
When welding, the filler metal must be compatible with the melting temperatures of aluminum. When the aluminum has a higher heat sensitivity than the filler material, its structural integrity is compromised. The aluminum could crack or break when it’s manipulated with heat. Choosing a filler in line with the chemical composition of aluminum will prevent this from happening.
