Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 22652-2008 "Valve Seal Surface Surfacing Welding Process Assessment". Compared with GB/T 22652-2008, the main change
The following is as follows.
--- Added "heap welding process specification", "pre-surfacing process specification", "surfacing welding evaluation report", "surfacing operation instruction book", "down conversion temperature"
"" and "post-weld heat treatment" terms (see 3.1);
--- Increased common abbreviations for surfacing process qualification (see 3.2);
--- Increased the base metal commonly used for valve surfacing and its categories and groups (see 5.2);
--- Modified the surfacing process evaluation factor (see 5.5, 5.1 of the.2008 edition);
--- Increased classification of filler metal (welding rod, welding wire, solder powder) and surfacing process qualification rules (see 5.3, 6.3);
--- Increased tubular surfacing specimens and specified sampling locations (see 7.1);
--- Added "Spoiler Process Specification Flow Chart" "Supplementary Specification for Base Metal, Filler Metal and Surfacing Method" "Pressure Welding Process Evaluation Form Push
Recommended format" 3 appendices (see Appendix A, Appendix B, Appendix C).
This standard was proposed by the China Machinery Industry Federation.
This standard is under the jurisdiction of the National Valve Standardization Technical Committee (SAC/TC188).
