9.1 The sample for analysis shall be taken from weld metal obtained with the electrode. The sample shall come from a weld pad or from a low dilution area in the fractured all-weld-metal tension specimen or the groove weld in Figs. 2 or 5. Areas where arc starts or craters exist shall be avoided. The top surface of the pad described in 8.3 and shown in Fig. 1 shall be removed and discarded, and a sample for analysis shall be obtained from the underlying metal by any appropriate mechanical means. The sample shall be free of slag and shall be taken at least 1 ⁄ 4 in. (6.4 mm) from the nearest surface of the base metal. The low dilution area in the fractured tension test specimen or in the groove weld in Figs. 2 or 5 shall be prepared for analysis by any suitable mechanical means.
the assemblies shall be as prescribed in Sections 9 through 14. Electrodes other than low hydrogen electrodes shall be tested without “conditioning.” Low hydrogen electrodes, if they have not been adequately protected against moisture pickup in storage, shall be held at a temperature of 500 to 800°F (260 to 427°C) for a minimum of one hour prior to testing. 8.3 Weld Pad. A weld pad, when required, shall be prepared as specified in Fig. 1. Base metal of any convenient size of the type specified in Table 5 shall be used as the base for the weld pad. The surface of the base metal on which the filler metal is deposited shall be clean. The pad shall be welded in the flat position with multiple layers to obtain undiluted weld metal. The preheat temperature shall not be less than

when the distance between the successive inclusions exceeds 6 times the length of the longest inclusions in the group. (3) No rounded indications in excess of those permitted by the radiographic standards in Fig. 7 according to the grade specified in Table 8. One in. (25 mm) of the weld measured from each end of the assembly shall be excluded from radiographic evaluation.
9.3 The results of the analysis shall meet the requirements of Table 7 for the classification of electrode under test. 10.
Radiographic Test
10.1 When required in Table 4, the groove weld described in 8.4.1 and shown in Fig. 2 or 5 shall be radiographed to evaluate the soundness of the weld metal. In preparation for radiography, the backing shall be removed, and both surfaces of the weld shall be machined or ground smooth. The finished surface of the weld may be flush with the plate or have a reasonably uniform reinforcement not exceeding 3 ⁄ 32 in. (2.4 mm). Both surfaces of the test assembly in the area of the weld shall be smooth enough to avoid difficulty in interpreting the radiograph.
10.4 A rounded indication is an indication (on the radiograph) whose length is no more than three times its width. Rounded indications may be circular, elliptical, conical, or irregular in shape, and they may have “tails.” The size of a rounded indication is the largest dimension of the indication, including any tail that may be present. The indication may be porosity or slag. Indications whose largest dimension does not exceed 1 ⁄ 64 in. (0.4 mm) shall be disregarded. Test assemblies with porosity indications larger than the largest rounded indications permitted in the radiographic standards do not meet the requirements of this specification.
10.2 The weld shall be radiographed in accordance with ASTM Method E142, Controlling Quality of Radiographic Testing. The quality level of inspection shall be 2-2T. 10.3 The soundness of the weld metal meets the requirements of this specification if the radiograph shows the following: (1) No cracks, no incomplete fusion or incomplete joint penetration (2) No slag inclusions longer than 1 ⁄ 4 in. (6.4 mm) or 1 ⁄ 3 of the thickness of the weld, whichever is greater, or no groups of slag inclusions in line that have an aggregate length greater than the thickness of the weld in a length 12 times the thickness of the weld, except
11.
11.1 One all-weld-metal tension test specimen shall be machined from the groove weld described in 8.4.1 as shown in Fig. 2 or 5. The dimensions of the specimen shall be as shown in Fig. 8. 11.2 For E6022 electrodes, one traverse tension test specimen shall be machined from the groove weld 13

FIG. 6
WELDING POSITIONS FOR FILLET WELD TEST ASSEMBLIES
described in 8.4.2 and Fig. 4. The dimensions of the specimen shall be as shown in Fig. 9.
for springback and the weld metal shall not contain openings in excess of 1 ⁄ 8 in. (3.2 mm) on the convex surface.
11.3 The tension specimens for all electrodes except the low hydrogen classifications shall be aged at 200 to 220°F (95 to 105°C) for 48 ±2 hours, and cooled in air to room temperature. All specimens shall be tested in the manner described in the tension testing section of AWS B4.0, Standard Methods for Mechanical Testing of Welds.
13.
13.1 Five Charpy V-notch impact test specimens, Fig. 12, shall be machined from the test assembly shown in Fig. 2 or 5, for those classifications for which impact testing is required in Table 4.
11.4 The results of the tension test shall meet the requirements specified in Table 2. 12.
13.2 The five specimens shall be tested in accordance with the fracture toughness testing section of AWS B4.0, Standard Methods for Mechanical Testing of Welds. The test temperature shall be that specified in Table 3 for the classification under test.
Bend Test (For E6022 Electrodes Only)
12.1 One longitudinal face bend specimen, as required in Table 4, shall be machined from the groove weld test assembly described in 8.4.2 and shown in Fig. 4. Dimensions of the specimen shall be as shown in Fig. 10.
13.3 In evaluating the test results for all the classifications that require impact testing, except E7018M, the lowest and highest values obtained shall be disregarded. Two of the three remaining values shall equal, or exceed, the specified 20 ft-lb (27J) energy level. One of the three may be lower, but not lower than 15 ftlb (20J). The average of the three shall not be less than the required 20 ft-lb (27J) energy level.
12.2 The bend specimen shall be aged at 200 to 220°F (95 to 105°C) for 48 ±2 hours then air cooled to room temperature and tested as required in 12.3. 12.3 The specimen shall be tested in the manner described in the bend testing section of AWS B4.0, Standard Methods for Mechanical Testing of Welds. The specimen shall be bent uniformly through 180 degrees over a 3 ⁄ 4 in. (19 mm) radius in any suitable jig. Three standard jigs are shown in Fig. 11. Positioning of the face bend specimen shall be such that the weld face of the last side welded is in tension.
13.4 In evaluating the results for E7018M, all five values shall be used. Four of the five values shall equal, or exceed, the specified 50 ft-lb (67J) energy level. One of the five may be lower, but not lower than 40 ft-lb (54J). The average of the five shall not be less than the required 50 ft-lb (67J) energy level.
12.4 Each specimen, after bending, shall conform to the 3 ⁄ 4 in. (19 mm) radius, with an appropriate allowance 16
