GB/T 22086-2008Recommendations for welding of aluminium and aluminium alloys (English PDF)

Foreword

This revised standard adopts ISO/T R17671-4.2002 "Recommended welding process welding of metallic materials - Part 4. aluminum and aluminum alloys Arc "(in English).

This standard is based on ISO/T R17671-4. redrafted 2002. This standard and ISO/T R17671-4. Compared to 2002, the technical content of repair Changed as follows.

--- Added Appendix A (informative) for explaining the clusters divided aluminum and aluminum alloy base material, and Appendix A of the original standard to Appendix B, Appendix B to Appendix C.

For ease of use, this section made the following editorial changes.

--- Deleted international standards foreword;

--- The standard name be changed to "aluminum and aluminum alloy welding technology recommended";

--- Of ISO/T R17671-4. other international standards referenced in 2002, has been adopted as the equivalent of the standard with our standard Generation for the corresponding international standards, it is not tantamount to the adoption of standards for the direct reference to international standards;

--- Delete references to normative documents of the European aluminum and aluminum alloy base material standards.

The Standard Appendix A, Appendix B, Appendix C is informative appendix.

This standard by the National Standardization Technical Committee welded and centralized.

This standard was drafted. Changchun Railway Vehicles Co., Ltd..

1 Scope

This standard specifies the recommended methods and technology of welding aluminum and aluminum alloy.

This standard applies to the welding of aluminum and aluminum alloy.

2 Normative references

3 Base metal

4 Factors that affect the performance of welded structures and components

Appendix B lists the negative factors that may arise due to welding, these factors are limited to conventional aluminum and aluminum alloy metallurgy technology, with

When also listed its causes and remedies.

In the design process of welded structures, it should consider the impact of the welding heat affected zone and weld properties, mechanical properties of the weld and heat affected zone Generally lower than the base metal.

In operation, it should pay attention to avoid the heat affected zone than any design, such as welding, arc abrasions and other temporary attachment.

5 Arc welding

When welding aluminum and aluminum alloys can be used as welding method (welding code See GB/T 5185).

--- 141 tungsten inert gas welding (TIG);

--- 15 plasma arc welding.
