Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard is GB/T 3965-1995 "Determination of hydrogen in deposited metal diffusion method" amendments. Compared with GB/T 3965-1995, The main modifications are as follows. --- Increasing the test outlined principles; --- Increasing the mercury method is suitable welding method, the sample size adjustment method of mercury, and are ISO 3690.2000 (E) regulations Consistency; --- Increasing the thermal conductivity method (including the original gas chromatography) collecting standardized, detailed operating procedures, retained the three types of samples in the original method size; --- Remove the basic process of glycerol; --- Arc plate and a lead plate length are predetermined minimum size; --- Test board dehydroepiandrosterone uniform regulation of "650 ℃ ± 10 ℃, insulation 1h, cooling in the furnace," and ISO 3690. consistent with the provisions of 2000 (E); and --- Copper fixture to adjust the size of general-purpose, depending on the circumstances the installation of water-cooling channel; --- Adjusted specimen preparation and clean-up requirements, increase the sample processing requirements beyond arbitration if they can quickly complete the operation may not be placed Cryogenic tank; --- Increased with ISO 3690. diffusion of hydrogen is calculated 2000 (E) the same amount of Y-type collector tube and the corresponding, while retaining the The same principle of the collected amount U-tube; --- Added mercury requirements for safe operation; --- Increase the weld metal diffusible hydrogen conversion formula; --- Increasing the test data recording forms of general recommendation; --- Increasing the normative Appendix A, lists the reliability evaluation elements; --- Increase the informative Appendix B, lists the glycerol and measurement program; --- Increase the informative Appendix C, and hydrogen diffusion assay methods are described. This standard uses redrafted law revision using ISO 3690.2000 "Welding and related methods ferritic steel arc weld metal Determination of hydrogen content "(in English). This standard and ISO 3690.2000 and its main technical difference between the following reasons. --- Remove the normative references ISO 14175 "Arc welding materials welding and cutting gas protection" in order to apply our Technical conditions; --- A combination of increased specimen type size, adjust the plate arc length and Crater plate requirements in order to operate; --- Increased heat input is calculated in order to control parameters; --- The simple jig into universal fixture, to facilitate the practical application; --- The three types of welding materials Welding data measurement and analysis of data tables and table combined into a common table, to facilitate data consolidation; --- Loosen the clamp and increases the cooling of ice time requirements to ensure test accuracy; --- Increase the principle amount collected the same U-tube and schematic, to facilitate the operation; --- Increasing the thermal conductivity method of collecting standardized, in order to operate. For ease of use, this standard also made the following editorial changes. --- Name to "deposited metal diffusible hydrogen determination"; --- Standard structure, according to the scope, outline, welding preparation, sample preparation, basic measurement method --- mercury method, determination of the basic square Several law --- report thermal conductivity method and the like to prepare the hydrogen content; --- Assess the reliability elements as a normative Annex A; --- Added two informative appendices, the contents of the Introduction and Appendix A merger into Appendix C.

1 Scope

This standard specifies the basic method for the determination of mercury and thermal conductivity method for the deposited metal diffusible hydrogen content. This standard applies to arc welding, submerged arc welding, gas shielded arc welding solid wire and flux cored arc welding methods such as welded Determination of hydrogen content of martensite, bainite and ferrite in the weld diffusion.

2 Overview

The electric arc method of welding materials deposited on the specimen a linear weld, after treatment at a given temperature and time income Set diffusible hydrogen, the hydrogen content was measured by displacement of mercury collected volume (mercury method) or thermal conductivity (thermal conductivity method). The results in terms of melting hectogram Metallized standard condition (0 ℃, 101.325kPa) under the diffusible hydrogen volume in units of mL/l00g. This standard mercury collected at room temperature for a few days or collected 72h at 45 ℃, suitable for B and C test block. The standard thermal conductivity method using a thermal conductivity detector, into a carrier gas hot extraction and collection method hydrogen, usually by gas chromatography for Type A, B and C test block. Wherein the carrier gas hot extraction method is a sample is heated to a higher temperature (up to 400 ℃), and continued to collect Analysis, rapid determination of diffusible hydrogen; hydrogen method is to set the sample is heated to a moderate temperature (usually 45 ℃ ~ 150 ℃) collection of diffusible hydrogen, after the end of Analyse.

3 welding preparation

3.1 Test Block 3.1.1 The test block should be used C≤0.18%, S≤0.02% of non-co-Jin Zhenjing steel. 3.1.2 Specimen combination of arc plate and lead the center specimen plates, dimensions shown in Figure 1. Each group comprising at least three test specimens combinations, secondary Using four specimens cut combinations. 3.1.3 Specimen processing should be carried out before the combination (650 ± 10) ℃ for 1h dehydrogenation process with the furnace cooling; can also be processed in a vacuum or Dry inert gas for the dehydrogenation process, if the air should be removed dehydrogenase scale. Test block should be stored in dry conditions. 3.1.4 Test Centre Block arc plate, lead plate plane grinding to complete a process should ensure uniform width, smooth and clean, straight into the contact surfaces Angle to ensure grip in the copper holder. 3.1.5 The label on the back of the center of the test piece marked, weighed and recorded as m1, A type specimen is accurate to 0.1g, B or C test block to the nearest 0.01g. 3.2 welding materials 3.2.1 Electrode For electrode test requirements are as follows. a) Categories and when tested, electrode diameter and welding parameters should be prepared with the mechanical properties of test parameters used for the same specimen. There is no requirement should be used electrodes, welding current than the manufacturer's recommended should be the maximum current of 15A or low φ4.0mm using the maximum 90% of the current tolerance control ± 10A. Adjust the welding speed in order to guarantee access to (10 ± 1.5) in the center of the A-type test block g The deposited metal, or acquired (4 ± 0.5) in the center of the B-type test block g of deposited metal, usually every 10mm seam consumption
