Description of ASTM-G58 2011ASTM G58 - 85(2011)Standard Practice for Preparation of Stress-Corrosion Test Specimens for WeldmentsActive Standard ASTM G58 | Developed by Subcommittee: G01.06 Book of Standards Volume: 03.02 ASTM G58Significance and Use The intent of this practice is to indicate standard welded specimens and welding procedures for evaluating the SCC characteristics of weldments in corrosive environments. The practice does not recommend the specific corrosive media that may be selected by the user depending upon the intent of his investigation. Specific corrosive media are included in Practices G 35, G 36, G 37, and G 44 . Other environments can be used as required. 1. Scope . 1.1 This practice covers procedures for the making and utilization of test specimens for the evaluation of weldments in stress-corrosion cracking (SCC) environments. 1.2 Test specimens are described in which ( a ) stresses are developed by the welding process only, ( b ) stresses are developed by an externally applied load in addition to the stresses due to welding, and ( c ) stresses are developed by an externally applied load only with residual welding stresses removed by annealing. 1.3 This practice is concerned only with the welded test specimen and not with the environmental aspects of stress-corrosion testing. Specific practices for the bending and loading of test specimens, as well as the stress considerations involved in preparation of C-rings, U-bend, bent-beam, and tension specimens are discussed in other ASTM standards. 1.4 The actual stress in test specimens removed from weldments is not precisely known because it depends upon the level of residual stress from the welding operation combined with the applied stress. A method for determining the magnitude and direction of residual stress which may be applicable to weldment is described in Test Method E837 . The reproducibility of test results is highly dependent on the preparation of the weldment, the type of test specimen tested, and the evaluation criteria used. Sufficient replication should be employed to determine the level of inherent variability in the specific test results that is consistent with the objectives of the test program. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. (For more specific safety hazards information, see Section 7.)
