Definitions
- the invention belongs to a test method for weldability of metallic materials. Background technique
- the technical problem to be solved by the present invention is to provide a test method which can provide a basis for the selection of the optimum preheating temperature of the dissimilar steel welding and the selection of the welding material.
- a test method for cold crack sensitivity of dissimilar steel comprising the following steps:
- Step 1 Prepare the test piece: Prepare the test piece according to GB 7675. 1-84 weldability test oblique Y-type groove weld crack test method. The form and size of the test piece are shown in Figure 1.
- the test electrode is optional and metal. Material 1 or metal material 2 matching electrode (high matching electrode, low matching electrode), optional Graded electrode between metal material 1 and metal material 2 (middle matching electrode); (so-called high-matching electrode, medium-matched electrode, low-matching electrode is like this: When dissimilar steel is welded, it is usually two different material grades. Steel grades are welded together. Therefore, when dissimilar steel is welded, if the electrode is selected according to the high grade ⁇ material, it can be defined as a high matching electrode. If the electrode is selected according to the low grade ⁇ material, it can be defined as a low matching electrode. The electrode between the two materials can be defined as the medium matching welding step 2, and the test is carried out:
- Step 3 evaluation The welding material and the preheating temperature at the surface crack rate of zero and the section crack rate of 10% are used as the welding material of the product and the preheating temperature before welding.
- Figure 1 is a schematic view showing the assembly of the test piece
- Figure 2 is a cross-sectional view taken along line A-A of Figure 1;
- Fig. 3 is a cross-sectional view taken along line B-B of Fig. 1; Specific form
- test piece Prepares the test piece. According to GB 4675. 1-84 Weldability Test, the Y-groove weld crack test method is used to prepare the test piece. The form and size of the test piece are shown in Figure 1.
- the test electrode can be selected from metal material 1 or metal material 2 Matching electrodes (high-matching electrodes, low-matching electrodes), also available in electrodes between metal material 1 and metal material 2 (middle matching electrode).
