The process not only improves the strength of these joints but also allows … Read more

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 Welding (GMAW) with filler metals 4043 or 5356. Always consider strength and welding methods to avoid defects. To achieve strong welds, beginners should focus on … Read more

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 up the machine and adjust welding parameters for best results. 4. Use the “hot and fast” technique. 5. Store filler metals properly to keep them … Read more

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 cleaning the oxide layer. Too much negative polarity can reduce weld quality. Always verify current settings before starting. Common issues with too much negative polarity … Read more
