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 985.1.
The partial modification of the use of ISO 9692-1.2003 "Welding and allied processes recommended welding groove - Part 1. Arc welding of steel
Welding, gas metal arc welding, gas welding, TIG welding and beam welding of high-energy "(in English).
This section according to ISO 9692-1.2003 redrafted. This standard and ISO 9692-1.2003 as compared to the technical content amended as follows.
--- Added Appendix A.
For ease of use, this section made the following editorial changes.
--- Deleted international standards foreword;
--- The standard name changed to "gas welding, arc welding, gas welding and beam welding Recommended groove";
--- To ISO 9692-1.2003 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 985-1988 "welding, SMAW basic form and GMAW welding groove and the size."
Section compared with the GB/T 985-1988 The main changes are as follows.
--- Increasing the scope of high-energy beam welding head;
--- Groove in accordance with the one-sided and double-sided welding welding division;
--- Recommended for each groove corresponding welding method;
--- Increased the narrow gap welding groove.
Appendix A of this section is an informative annex.

3 General
This section on the principle of full penetration of the provisions of the butt joint groove forms and sizes. For incomplete penetration butt joints, allowing
Xu other forms of welding groove. Welding symbols see GB/T 324. Welding position See GB/T 16672.
4 welding method
Table 1 to Table 4 provides all kinds of groove for the appropriate welding method. If necessary, it can also be used in combination of two or more applicable methods
welding.
Welding code See GB/T 5185.
5 groove bottom grinding
From the process point of view, without the blunt edge of the groove can be polished to its roots base, retain a certain amount of blunt edges (2mm
Or less).
6 groove recommendation forms and sizes
6.1 single-sided butt weld groove
Table provides single-sided butt welding groove forms and dimensions 1. When the cross-position welding, bevel (or groove face angle) may be appropriate to increase,
And allow asymmetric. Given clearance also apply to tack welding conditions.
6.2 double-sided butt weld groove
Table 2 provides double-sided butt welding groove forms and sizes. When the cross-position welding, bevel (or groove face angle) may be appropriate to increase,
And allow asymmetric. Given clearance also apply to tack welding conditions.
6.3 single-sided fillet weld
Table 3 specifies the form of joint-sided fillet welds.
6.4 double-sided fillet welds
Table 4 provides a form fitting double fillet welds.
