GB/T 36037-2018Fluxes for submerged arc welding and electroslag welding (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the redrafted method to amend ISO 14174.2012 "Classification of fluxes for welding of submerged arc welding and electroslag welding of welding materials."

This standard compares with ISO 14174.2012 in terms of structure, according to classification, technical requirements, test methods, re-inspection and supply technology

Prepare the pieces.

The technical differences between this standard and ISO 14174.2012 and its causes are as follows.

--- With regard to normative references, this standard has made adjustments with technical differences to adapt to China's technical conditions and adjust the situation.

The focus is reflected in Chapter 2, "Normative References," and the specific adjustments are as follows.

* Adding reference GB/T 25778;

* Replace ISO 3960 with GB/T 3965 modified to adopt international standards;

* Replace ISO 14171 with GB/T 5293 modified to adopt international standards;

* Replace GB/T 29713 with international standards instead of ISO 14343;

* Delete ISO 80000-1.2009.

--- Increased proliferation of hydrogen code H15 for ease of use.

---According to the actual situation in China, increase the code number 2.5 in the particle size code, and provide the corresponding reference domestic common meshes, in order to facilitate

application.

---According to the actual situation in China, the requirements for the sulfur and phosphorus content of the flux have been increased.

---According to the actual situation in China, the requirements for the flux welding process performance have been increased.

--- Increased the provisions of the flux particle size test method.

--- The welding wire used for the metallurgical performance test and the determination of diffusible hydrogen content has increased the SU26 welding wire that is commonly used in China.

This standard also made the following editorial changes.

--- The standard name was changed to "Flux for SAW and Electroslag Welding".

This standard is proposed and managed by the National Welding Standardization Technical Committee (SAC/TC55).
