Welding Wisdom for Professionals and Beginners Alike.

Sand cast aluminum is typically weldable. Use GTAW or MIG welding for repairs. An aluminum MIG welder and shielding gas, like argon, are essential. Preheat the castings to prevent cracking….

Aluminum has good ductility and high thermal and electrical conductivity. Its oxide layer can complicate welding but also protects the metal. Weldability differs among alloy series, such as 5xxx and…

GMAW (Gas Metal Arc Welding) is a welding process that uses a continuous wire electrode and shielding gas to protect the weld from contaminants. It is effective for aluminum. Important…

QC-10 is a high-strength aluminum alloy made for injection molds. It has great thermal conductivity and is easy to machine. You can weld it using electric arc methods with tungsten…

Metal stitching is an industrial technique for repairing cracked or broken aluminum components. This cold process is a welding alternative. It uses specialized metal stitches to join fractured pieces, restoring…

Welding 6061 aluminum needs shielding gases like argon and helium for their inert properties. Effective heat treatment preserves the aluminum’s mechanical properties. Using proper welding techniques ensures strong welds and…

The welding shade chart for aluminum shows the right lens shades for different amperages. Use shades #5 to #8 for lower currents (80-100 A). For higher currents, choose shades #10…

Welding steel to cast aluminum using arc welding is difficult. The high heat can form brittle intermetallic compounds that weaken the joint. To tackle these challenges, consider using filler materials…

Welding stress in aluminum is the residual stress that forms during welding. When aluminum melts and solidifies, it shrinks, causing stress around the weld. Post-weld stress relief is often not…
