Welding Wisdom for Professionals and Beginners Alike.

When welding aluminum with AC, use pure tungsten or zirconiated tungsten electrodes. Avoid thoriated tungsten. Choose a diameter that matches your welding current. Larger-diameter electrodes work best for AC welding….

To prepare tungsten for aluminum welding, use a 1/8-inch tungsten. Sharpen it to a 60-degree angle. Strike the arc slowly with a vertical torch. Gradually increase the amperage until the…

Use 1/8 inch tungsten for TIG welding aluminum. Cut the tungsten at a 60-degree angle. Strike the arc slowly while keeping the torch vertical. Increase amperage gradually until the tungsten…

Excessive heat causes tungsten splitting when welding aluminum. To prevent overheating, ensure the tungsten does not turn red. If it does, cool it in water. Use 100% tungsten electrodes, like…

Welding aluminum differs due to its oxide layer. This layer protects against corrosion and abrasion. It is tougher than aluminum and acts as an insulator, making the welding process challenging….

Moving the welding torch too quickly can cause the tungsten to blacken after welding aluminum. Rapid torch movement disrupts the gas shield during post flow, exposing the tungsten to air….

Recent trends in aluminum resistance spot welding for the auto industry include advancements in welding technology and the use of new aluminum alloys. These innovations help reduce manufacturing costs. Lightweight…

Tri-mix for aluminum welding usually contains 10% argon, 85-90% helium, and 2-5% CO2. This gas blend creates a hotter arc, which is ideal for thicker aluminum materials. Higher helium content…

To weld aluminum effectively, start by cleaning the surface with a wire brush to remove oxide. Use TIG welding techniques for corner joints. A push-pull wire feed provides better control….
