Foreword

This standard is identical with ISO 9015-1.2001 "Destructive tests on welds in metallic materials hardness test hardness test Arc Welding" (In English). This standard is equivalent translation ISO 9015-1.2001. For ease of use, this standard made the following editorial changes. --- Deleted international standards foreword; --- The standard name be changed to "welded joint hardness test methods"; --- To ISO 9015-1.2001 and other international standards referenced, there is tantamount to the adoption of a standard for the use of standards in place Corresponding to international standards, is not identical with direct reference to international standards for our standards. This standard is GB/T 2654-1989 "welded joint and surfacing metal hardness test methods" amendments. This standard compared with GB/T 2654-1989, the main modifications are as follows. --- Added "principle", "symbol and description", "Sample Preparation" part; --- Deleting the original standard "welding metal hardness test" of the content; --- Added "Test Sample Report" section. The Standard Appendix A, Appendix B is an informative annex. Since the implementation of this standard replaces GB/T 2654-1989. This standard by the National Standardization Technical Committee welded and centralized. This standard was drafted. Harbin Welding Institute. The main drafters of this standard. a Bing Huang, Qu peacekeeping force. This standard replaces the standards previously issued as follows. --- GB 2654-1981, GB/T 2654-1989.
