2024 Wedding Property
Alloy	Resistance welding	Melting welding	Argon arc welding	Note
2A11	Good	Worse	Worse	For gas welding and argon arc welding of aluminum alloy as solder, tend to form crystalline cracks; 4A01 alloy solder, forming cracks tend to be significantly reduced, but the strength of welded joint is greatly reduced, such as heat treatment after welding, the joint strength is close to the substrate, but the ductility decreases.
