PnEING EVERETT SECTION 34 11 16 NEW RAII SPUR VJELDING OF RAIL VJORK OROER 10305 2. Radiagraphic Test: The tesl samples for pressure weld and Ihermite welda shell be radiographically tesled in eccordance with ASTM �: 142, 'Controlling Quality ol Radiographic Testing.' a. The radiographic lesta shell detect flaws in welds wilh suHicient detail to establiah the ability of lhe weld to meet lhe requiremenla spec�ed herein. II a defective weld is detected, lhe welding procedure shall be madified and lhe tesls repeated. b. At least four areas ol each weld shall be rediographed: the head, lhe web, and each side of the base. The presence of any cracka or voids shall be cause for rejection. c. Each radiographic film ahell be identified, through the use o1 numbers and letters, t� show lhe Contract Number, the Rail identity, the Date, Inspection Agency, and the View. A letter u� ceR�cation shall be submitted with each film to Boeing Construclion Maneger. The letter shali state the information given on the film and whether lhe weld meets or tails to meel the requiremente specified herein. d. Each weld shall have complele fusion with no evidence o1 suAace or internal cracks or fiasures. In thermite welds, porosity or slag inclusion will be tolerated provided lhet the largesl defecl doas not exceed 1/8 inch in any dimension and the tolal area of all detects does not exceed 0.06 square inches. e. Nondeslructive inspection of inetal welds by radiographic use ol nuclear by- product materials ahall be In accordance with United States Nuclear Regulatory Commission Rules and Regulations, Tille 10, Atomic Energy, PaA 20, 'Standards for Protection Ageinat Radiation' Transportation, handling, and storage of hazardous materials used in nondestruclive inspection o1 welds shell be peRormed only by or under the supervision of e persan of proven experience and ebility operating under a proper license. f. The laboralory end procedure to be utilized and radiographic lesting shall be submitted lo the Boeing Conslruction Mer.ager for approval. 3 Ultrasonic Test end Magnetic Perticle Test: The test samples for pressure end thermite welds chall be ultrasonically tesled and tested using Ihe magnelic particle method. Certified test reports shall be foiwardeA to Bceing Construction Menager tor review. Acceptance shall be in accordance with A�Kicie 1.04E. 4 Dynamic Test for Sample Rail Welda One ot each type sample weld thet has passed the radiographic and ultrasonic testing shall be subjecled to the tollowing dynemic testi�g The test sample rail wetd shall be supported on 36-inch cenlers with the weld located between eupparts as shown in Figure 02041-1, Repeated loads shall be applied wilh two hydraulic rams F,pply loads to the rail allematively el Poinls A and B Each load shall vary fron zero to 44,400 pounds in Ihe approximate shape of a sine curve Loads shell be appl'ed for two million cycles Application of load at Point A and lhen at Poinl 8 shall constiti te one cycle. Rail dellection shall be measured every 500,000 load cycles et Poinl!,and recorded to the nearest 0 001 inch. loads shall be monitored with load cells placed between each ram and the rail head. These load cells sha�l be calibrated prior to comme uement of the test program. a Ac;eptance Criteria: Afler 2,000.000 cycles, the rail weld Joint shail show no evi�lence of failure by bending The deilection of Bie rail shall not exceed 0 065 inch during the test DeOection shall be measured after every 500.000 load cycles. 5 Slow Bend Tesl for Sample Rail Welds One of each type sample weld which has passed the radiographic and ultrasoNc testing ehall be subJected to Ihe Slow Bend Tests Permit Set 34 11 76-4 SeDtember 23, 2011
