“…The most wellknown are the " Strain theory of hot tears" [10] and the " Shrinkage-Brittleness theory" [11] which later were combined into Borland's combined theory known as the "Generalized theory" [12]. There are other theories as well [13][14][15][16] where the following material factors are believed to affect the susceptibility to hot cracking [9]:…”

This paper reviews the inherent weldability of precipitation hardening Ni-based superalloys commonly used in structural components of aircraft engines. Weldability often refers to alloys resistant to cracking during welding which for superalloys is difficult to comprehend since specific liquation and cracking mechanism may differ in this class of materials. A new procedure of evaluating the weldability as well as susceptibility towards strain age cracking of these alloys is proposed in which standard metallographic examinations are used to understand the cracking mechanisms in parallel with systematic ductility measurements such as Varestraint or Gleeble testing.
