FATIGUE CHARACTERISTICS OF WELDED EXTEN-60 STEEL

THREE WELDING PROCEDURES WERE USED IN A WELD QUALIFICATION TEST, ONLY ONE OF WHICH PROVED SATISFACTORY. SPECIMEN VARIABLES WERE: (1) PLAIN PLATE SPECIMENS; (2) AS-WELDED BUTT JOINTS; AND (3) WELDED BUTT JOINT WITH REINFORCEDMENT REMOVED. COMPLETE REVERSAL, ZERO-TO-TENSION AND ON-HALF TENSION-TO-TENSION STRESS CYCLES WERE EMPLOYED. IT WAS CONCLUDED THAT: (1) THE FATIGUE STRENGTHS OBTAINED ARE IN GOOD AGREEMENT WITH EXPECTATIONS BASED ON OTHER LABORATORY DATA, AND (2) WELDING OF THIS MATERIAL CAUSED SOME CONCERN, SINCE MINOR CHANGES IN WELDING PROCEDURE PRODUCED MARKED CHANGES IN THE AMOUNT OF POROSITY PRESENT IN THE WELD. /FHWA/
