Steels with high carbon equivalent have poor weldability, because in these steels during welding |
| A. | carbon and other alloying elements get oxidised from the weld pool. |
| B. | excessive ferrite forms in the heat affected zone leading to poor toughness of the weld. |
| C. | martensite forms in the heat affected zone leading to poor toughness/ductility of the weld. |
| D. | segregation of carbon and other element occurs in the weld pool leading to poor properties of the weld. |
