FAQs

Can You Weld 6063 to 6061?

Yes, you can weld 6063 to 6061 aluminum. Both alloys belong to the 6000 series and have similar magnesium and silicon content, making them compatible for welding. However, welding these alloys can reduce their strength in the heat-affected zone. Proper welding techniques and post-weld heat treatments can help mitigate strength loss and ensure a reliable joint.
