Workability - Cold Fair
Machinability Excellent
Weldability - Gas Poor
Weldability - Arc Poor
Weldability - Resistance Poor
Brazability Poor
Solderability Fair

Alloy 2011 has extremely poor weldability and thus welding is not recommended. However, as it is used for machined parts there is rarely a need to weld this alloy.
