- Arc Burns. Localized points of surface melting caused by arcing between electrodes or ground and pipe surface. 电弧烧伤。由于电极(含接地极)与管子表面之间起弧而产生的局部表面熔化点。
- Quantitative analyses have been made on the composition of corroded products and the macro-residual stress on the pipe surface by EDX and XRD. 应用 X 射线能谱仪和 X 射线衍射仪分别对腐蚀产物及管表面宏观残余应力进行定量分析.
- Contact Mark. Intermittent marks adjacent to the weld line resulting from the electrical contact between the electrodes supplying the welding current and the pipe surface. 触点痕。由于供焊接电流的电极与管子表面间的电接触,致使在焊缝线附近产生不连续痕迹。
- Metal separations, resulting from imperfections at the edges of the plate or skelp, parallel to the surface, which turn toward the ID or OD pipe surface when the edges are upset during welding. 由于钢板或管坯边缘存在的缺欠所产生的平行于对焊表面的金属分离,当焊接过程中对焊边顶锻时,这些缺欠超者管子内表面或外表面翘曲。
- Using a brush or applicator size no less than 1/2 the pipe diameter, apply a liberal coat of solvent cement to the primed pipe surface, then apply a light to medium coat to the primed fitting socket. 采用一把尺寸不小于管道半径的刷子或涂敷工具,将足够量的液状粘固剂涂敷在上完底漆的管道表面,然后在上完底漆的管件承插部位涂敷较薄或中等厚度的液状粘固剂涂层。
