Other Factors Affecting Weldability
Filler metal
Must be compatible with base metal(s)
In general, elements mixed in liquid state that form a solid solution upon solidification do not cause a problem
Surface conditions
Moisture can result in porosity in fusion zone
Oxides and other films on metal surfaces can prevent adequate contact and fusion
