Foreword

GB/T 985 is divided into the following four parts. --- GB/T 985.1 gas welding, arc welding, gas welding and beam welding Recommended groove; --- GB/T 985.2 SAW recommendation groove; --- GB/T 985.3 aluminum and aluminum alloy gas welding recommendation groove; --- GB/T 985.4 clad steel recommendation groove. This section GB/T 985.2. The partial modification of the use of ISO 9692-2.1998 "Welding and allied processes recommended welding groove - Part 2. Submerged arc welding of steel" (In English). This section according to ISO 9692-2.1998 redrafted. This standard and ISO 9692-2.1998 as compared to the technical content amended as follows. --- Normative references removed ISO 3834, ISO 9692 and ISO 9956; --- Added Appendix A. For ease of use, this section made the following editorial changes. --- Deleted international standards foreword; --- The standard name changed to "SAW recommended Groove"; --- To ISO 9692-2.1998 and other international standards referenced, or modified have been adopted as the equivalent of a standard by our standards Instead of the corresponding international standards; --- Table numbers were adjusted. This Part replaces GB/T 986-1988 "submerged arc weld groove in the basic form and size." Section compared with the GB/T 986-1988 The main changes are as follows. --- Groove in accordance with the one-sided and double-sided welding welding division; --- Increased the narrow gap welding groove. Appendix A of this section is an informative annex. This part of the National Standardization Technical Committee welded and centralized. This section is drafted.
