Professional Appleton Aluminum Welding Services
Why Choose Specialized Aluminum Welding?
Aluminum is lightweight, corrosion-resistant and great at conducting heat. However, welding properly takes skill and experience. It requires clean surfaces, tight process control and shielding gas to prevent oxidation. We prevent weak joints, warping and costly rework by staying focused on every detail. Each weld is handled with discipline and precision. Whether you’re working with extrusions, castings or formed parts, we make sure every weld meets your specs.

Frequently Asked Aluminum Welding Questions
Common questions about our welding services.
Can You MIG Weld Aluminum?
You can MIG weld aluminum using a spool gun and 100% argon shielding gas. MIG welding aluminum requires a push technique, higher travel speeds and clean base metal. Use ER4043 or ER5356 wire for most applications and set the welder to high voltage due to aluminum’s high thermal conductivity.
Can You TIG Weld Aluminum?
You can TIG weld aluminum using alternating current (AC) and a tungsten electrode. TIG welding provides precise control and clean welds, making it ideal for thin aluminum. Use 100% argon gas and a foot pedal for amperage control. Clean the metal thoroughly before welding to remove oxidation.
Can You Stick Weld Aluminum?
You can stick weld aluminum, but it is not recommended due to poor weld quality and difficulty controlling heat. Stick welding aluminum requires special electrodes like E4043 and high amperage settings. The process produces more spatter and weaker welds compared to TIG or MIG welding methods.
Can You Weld Cast Aluminum?
You can weld cast aluminum, but it requires proper preparation due to its high porosity and impurities. Clean the surface thoroughly, preheat the metal to 300–400°F and use TIG welding with ER4043 or ER5356 filler rods. Use AC current and 100% argon shielding gas for best results.
Can You Weld Aluminum with a Flux Core Welder?
You cannot weld aluminum effectively with a standard flux core welder. Flux core welding is designed for steel and lacks the shielding gas and wire compatibility needed for aluminum. Aluminum requires MIG or TIG welding with argon gas and appropriate filler wire to achieve strong, clean welds.
What Gas Do You Use to Weld Aluminum?
Use 100% argon gas to weld aluminum. Argon provides a stable arc and clean welds, making it ideal for both TIG and MIG aluminum welding. For thicker sections or spray transfer MIG welding, a helium-argon mix can increase heat input, but pure argon remains the standard choice.
