Steels with high carbon equivalent have poor Weldability, because in these steels during welding________?
ASegregation of carbon and other element occurs in the weld pool leading to poor properties of
BMartensite forms in the heat affected zone leading to poor toughness/ductility of the weld
CExcessive ferrite forms in the heat affected zone leading to poor toughness of the weld
DCarbon and other alloying elements get oxidised from the weld pool
Correct answer
B. Martensite forms in the heat affected zone leading to poor toughness/ductility of the weld
Explanation
The correct answer is Martensite forms in the heat affected zone leading to poor toughness/ductility of the weld.
