Q3 Single choice Flag Codes/standards sometimes specify impact testing of weldments at minimum design metal temperatures to: A Assure that the welded material has sufficient yield strength to avoid brittle fracture. B Assure that the welded material has sufficient ductility to assist brittle fracture. C Assure that the welded material has sufficient toughness to resist brittle fracture. D Assure that the welded material has sufficient tensile strength to avoid failure at design loads. Correct answer
