JB/T3158—1999
This standard adopts ISO5184:1979 "Straight Electrodes for Resistance Spot Welding" in a non-equivalent manner. This standard is a revision of JB3158-82 "Straight Electrodes for Resistance Spot Welding". According to the requirements of GB/T 1.1--1993 and GB/T 1.3--1997, only editorial changes have been made to JB3158--82. From the date of implementation, this standard will replace JB3158-82. Appendix A of this standard is a reminder appendix.
This standard is proposed and managed by the National Technical Committee for Standardization of Electric Welding Machines. The drafting units of this standard are: Shanghai Electric Science Research Institute, Tuhai Electric Welding Machine Factory. The main drafters of this standard are: Ni Hongxing and Chen Guoyu. 1
