Foreword

GB/T 22085 "electron beam and laser welding joint quality levels for imperfection" is divided into two parts. --- Part 1. Steel; --- Part 2. Aluminium and its alloys. This section GB/T 22085 Part 1. This part identical with ISO 13919-1.1996 "electron beam welding and laser welded joints quality levels for imperfection Part 1 Score. Steel "(in English). This section is equivalent translation ISO 13919-1.1996. For ease of use, this section made the following editorial changes. --- Deleted international standards foreword; --- The standard name be changed to "electron beam and laser welding joint quality levels for imperfections - Part 1. Steel"; --- Of ISO 13919-1.1996 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; --- The ISO 13919-1.1996 in the "Description" incorporated in Appendix A.
