Factors of Weldability

 

 
   
  • Hot cracking susceptibility.

 
  • Cracking after solidification (cold cracking).

 
  • Thermal cycle and its effect on weld metal and base metal properties.

 
  • Micro structural changes due to welding.

 
  • Gas-metal , slag-metal reactions.

 
  • Changes in chemical composition by volatization of alloying elements.
