- (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
