Foreword
This section GB/T 902 (hereinafter referred to in this section) is one of the national standard "stud welding and welding nails" product family standard, the series
include.
--- GB/T 902.1-2008 manual welding with welding studs;
--- GB/T 902.3-2008 discharge welding welding studs;
--- GB/T 902.4-2010 short cycle stud welding arc stud welding;
--- GB/T 10432.1-2010 arc stud welding with no head studs;
--- GB/T 10432.2-2010 short cycle stud welding arc welding with headless nails;
--- GB/T 10432.3-2010 discharge welding of the headless studs;
--- GB/T 10433-2002 arc stud welding with welding cylinder head nails.
This section is GB/T 902 Part 2.
The partial modification of the use of ISO 13918.2008 "Arc welding studs and magnetic" provides a threaded stud (PD type), with reduced bar
Threaded stud (RD type) and an inner threaded stud (ID type), magnetic ring and its supporting used (PF, RF and UF type) (in English).
This part of ISO 13918.2008 provisions threaded stud (PD type), with a reduced rod threaded stud (RD type) and an inner threaded stud
(ID type) and magnetic (PF, RF and UF type) the main changes are as follows.
--- ISO 13918 certification provisions covering products, market access for testing and factory production control, and ISO /TC2 "fastening
Member "has developed different fastener product standards, there are also quite different from the reality of the current situation, so were not used;
--- In the reference file, instead of using our standards with international standards (Chapter 2);
--- ISO 13918 does not provide packaging technology requirements in this section shall be specified (see Table 3).
--- ISO 13918 does not provide for a simplified mark, according to this part of GB/T 1237 presents a simplified markup (see 6.1.2).
This Part replaces GB/T 902.2-1989 "Mobile arc welding studs."
This section compared with the GB/T 902.2-1989 main changes are as follows.
--- Increase Preface;
--- Adjust the reference standard (Chapter 2);
--- PD with the old standard type A and B is basically the same, the new type of RD and ID type and adjust the specification (Chapter 3);
--- Increase stainless steel welded studs, and provides performance rating. 4.8 carbon steel and stainless steel A2-50 (see Table 7).

3 Dimensions
3.1 General
--- Weld length (l2) is the design value. Appropriately controlled welding to maintain l2 within ± 1mm. Under special conditions, such as penetration means
Accessories Stud Welding l2 may be different from the nominal value.
--- For PD, RD and ID-type studs tip central portion, namely in the shape of the inner diameter d2/3 range is determined by the manufacturer. In mining
The case of using solder tip rod with compression-fit shape is determined by the manufacturer, such as a band can not exceed the 0.5d1
flat.
--- 3 shown in FIGS. 1 to size after the welding is a reference value.
--- A) of Figure 1 is not specified dimensions and tolerances, determined by the manufacturer. This also applies to the shape of the stud welding position changes,
Such as drilling and slotting not affect the weldability.
--- Threaded stud (PD) and a threaded stud with a reduced lever (RD) of the tip should be fitted with press-fitted aluminum rod or aluminum coating. However, stainless steel
Under studs and diameter ≤10mm, and inert gas welding of the case, this requirement may be omitted.
D7 --- bead diameter is the main factor affecting the quality of welding; changes in other dimensions without impairing the quality of welding.
--- Quality stud welding, see Appendix B.
