Q13. Procedure and performance macro-examination specimens are etched to give clear definition of: · (a) weld metal and heat affected zone. (b) inclusions and porosity. (c) root of the weld. ANS: a Q14. Under what conditions are tension tests considered acceptable if the specimen breaks in the base metal outside the weld or fusion line? (a) Lf there are no open defects exceeding 1/16" measured In any direction. (b) If the strength is not more than 5% below the specified minimum tensile strength of the base metal. (c) Lf there are no open defects exceeding 1/8” in the bond line. ANS: a Charlie Chong/ Fion Zhang
