Welding Wisdom for Professionals and Beginners Alike.

General Motors (GM) has created a clear definition of aluminum spot welding. This innovative process, known as resistance spot welding, uses a multi-ring domed electrode. It effectively joins lightweight metal…

Stick welding aluminum can be effective in breezy conditions. A DC stick welder uses the electrode negative (DCEN) method, which can be more effective than MIG and TIG welding in…

For welding aluminum, choose the 5XXX or 6XXX series alloys. The 5XXX series offers great weldability and low crack sensitivity. Use Gas Tungsten Arc Welding (GTAW) or Gas Metal Arc…

Consider these five essential tips for TIG welding aluminum. 1. Choose the right filler metal for your project. 2. Prepare the base material thoroughly for a strong bond. 3. Set…

Aluminum welding needs the right polarity for best results. Use DC+ (DCEP) for better penetration and stability. Keep AC balance low (below 20%) for penetration and high (above 30%) for…

Repairing aluminum mountain bike frames poses challenges. Welding produces heat that changes the temper of the aluminum alloy. After welding, heat treatment is necessary to regain the frame’s strength. Understanding…

Aluminum oxide has a higher melting point than aluminum. This creates welding challenges. The oxide layer acts as an insulator, causing arc start problems. High heat is needed to penetrate…

Aluminum nose wire welding uses gas and contact welding techniques. Ensure correct machine settings and clean metal surfaces. Use aluminum MIG welding wire with the right shielding gas and DCRP…

TIG welding aluminum pipe needs skill in controlling shielding gas flow, AC balance, and frequency. Beginners should start with flat aluminum and work on consistent bead placement. Using effective techniques…
