Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a member to be welded and a welding finished member 15 made of the member to be welded. [Prior Art] Soldering of a metal part has been welded, and welding The internal stress is generated by the heat of the field, and the stress to be welded is mainly applied to the plane direction due to the welding stress, but the effect in the thickness direction is not large. Therefore, the effect of the welding stress is Q. It is easy to produce local deformation, which causes the whole part to be welded to produce fingerprints and corners on the plane. ♦ The rain affects the appearance and performance of the product after welding. 阙The deformation caused by the welding stress is often caused by the welding pure product. Correction is made at the weld and adjacent welds and joints, so that the flatness of the parts to be welded is obtained by -t recovery. ^ 'For some products where the weld is located inside the corner or corner of the workpiece', it cannot be corrected by the medium pressure method. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a welded part to be subjected to stress deformation and a welded finished part made of the piece to be welded. _] - the material to be welded, the part to be welded is a plate-like structure and has a portion to be welded '4 a portion of the portion to be welded adjacent to the portion to be welded has a continuous stress relief groove' along the stress relief groove along the piece to be welded Extending and intersecting the edge of the member to be welded. [_ - After welding, the piece, including the part to be welded and the part to be welded, is welded to the part to be welded, and the part to be welded is 098123304. Form No. A0101 Page 3 / Total 13 Page 0982039671 -0 201102207 Forming a weld 'The weld to be welded is provided with a continuous stress relief groove adjacent to the weld'. The stress relief groove extends along the weld and intersects the edge of the weld to be welded. [0009] [0009] [0010] 098123304 The portion to be welded is provided with a continuous stress relief groove on the portion to be welded. When the workpiece to be welded is welded to the workpiece, the position of the portion to be welded is adjacent. The generated welding stress can be released along the stress relief groove, and the parts of the portion to be welded adjacent to the portion to be welded are not deformed. And the "Hail stress relief groove intersects the edge of the member to be welded, that is, the stress relief groove extends to the edge of the member to be welded, so that the welding stress can be completely released, and the partial welding stress is prevented from being transferred from the stress relief groove to the portion to be welded. The other parts of the welded part, in turn, ensure that other parts of the part to be welded are not deformed by the welding stress. [Embodiment] Hereinafter, a member to be welded and a welding method of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. Referring to Fig. 1, the welding completion member 100 includes a workpiece to be welded 10 and a workpiece 3 which are welded to each other. Referring to Fig. 2, the member to be welded 1G is a plate-like structure having a splicing surface to surround the edge 13 of the _ plane U, and (4) the welding surface _ the near edge is formed to form the portion 15 to be welded. The weld surface u is adjacent to the portion to be welded, that is, the portion adjacent to the edge 13 is provided with a stress release_. The stress relief groove W is continuous and smooth on the dP11. The edge 13 intersects, i.e., the stress relief groove 17 extends to the edge 13 of the member to be welded. The groove of the stress relief groove 17 has a groove depth smaller than that of the member to be welded, and the cross-face has a ridge. The present embodiment is in the form of a towel number _1 ^ 4 I / * 13 1 201102207 [0012] [0014] 〇 π is a continuous wave-shaped extending groove, and the cross-section of the porch is Fox shape (Figure 4). In the present embodiment, the guard member 30 is a housing structure including a back plate 31 and a bent side 33 formed by f-folding from the back plate 31. The bent side coffee has an end face 33. Please refer to FIG. 2 to FIG. 4 at the same time, and weld the member to be welded 1G and the guard 3 () to make the portion to be welded 1 to be welded and the guard 3 () The end face 331 of the bent side 33 is welded, and after welding, a weld bead 19 is formed which is adjacent to the stress relief groove 17 on the member 10 to be welded. In the present embodiment, the thickness of the member to be welded 10 is smaller than the thickness of the workpiece 30, and the workpiece 3 is more likely to be deformed. Therefore, the stress relief groove 17 is opened on the member to be welded 10. In the welding completion member 100, since the stress relief groove 17 is opened adjacent to the weld bead 19 on the to-be-welded member 1 , when the workpiece 1 to be welded is welded to the workpiece 3, the welding stress generated from the stress relief groove can be obtained from the stress relief groove. 17 is released. Since the stress relief groove 17 is continuously extended, it is ensured that the welding stress generated by any one of the welds 19 can be released by the adjacent one of the stress relief grooves 17 during the coal &process; 17 bending extension, that is, extending on the welding surface 11 along the "X" and "Y" directions shown in FIG. 4, can ensure that the welding stress in each direction generated at the weld 19 is released, thereby ensuring the parts to be welded. 1 The flatness and corner dimensional accuracy of the portion adjacent to the portion to be welded 15 on the 。. The stress relief groove 17 intersects the edge 13 of the member to be welded 10, so that the welding stress generated during the welding is completely released, further ensuring the connection The other parts of the piece 1 away from the portion 15 to be welded are also unaffected by the welding stress. 098123304 Form No. A0101 Page 5 of 13 0982039671-0 201102207 Deformation [0015] [0017] [0018] [ 0019] the to be welded 1 The profile of the 杈 杈 应力 应力 丨 , , , , , , , , , , , , , , , , , , , , , , , 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓 轮廓The stress relief groove can also be in the form of a plurality of rounded fox-like extensions.
