当构件用手工电弧焊时,为减少焊接变形,改善应力分布,一般需采取一些工艺措施,如间隔、对称、逆向分段等施焊方法。平板闸门埋件形状各异、板厚不同,焊缝长短不一,须根据其结构特点,编制切实可行的焊接工艺,否则,将产生较大的应力与变形,难以保证质量。 When using manual electric arc welding components, in order to reduce the welding deformation, improve the stress distribution, generally need to take some measures, such as spacing, symmetry, reverse segmentation and other welding methods. Flat gate buried parts of different shapes, different thickness, the weld varies, according to its structural characteristics, the preparation of practical welding process, otherwise, will have greater stress and deformation, it is difficult to ensure the quality.
