Q
Steels with high carbon equivalent have poor Weldability, because in these steels during welding________________?
-
A
A. Carbon and other alloying elements get oxidised from the weld pool
-
B
B. Excessive ferrite forms in the heat affected zone leading to poor toughness of the weld
-
C
C. Martensite forms in the heat affected zone leading to poor toughness/ductility of the weld
-
D
D. Segregation of carbon and other element occurs in the weld pool leading to poor properties of
Correct Answer:
C. C. Martensite forms in the heat affected zone leading to poor toughness/ductility of the weld
