焊接过程是钢制压力管道工程施工的关键过程和主要过程。压力管道组队、焊接质量的的好坏直接影响管道介质的流速流向、管道磨损情况和安全运行。因此对压力管道的焊接质量有着极为严格的要求,除要求焊接接头为完全熔透焊缝外,对压力管道的耐蚀性以及焊缝表明的质量也有着具体的焊接标准、焊缝的表面(罐内、外)应平缓、均匀、不得
The welding process is the key process and main process of steel pressure pipeline construction. Pressure pipeline team, the quality of the welding quality of a direct impact on the pipeline medium flow velocity, pipeline wear and safe operation. Therefore, the quality of the pressure pipe welding has very strict requirements, in addition to requiring the weld joint is completely through the weld, the corrosion resistance of the pressure pipe and weld quality also shows the specific welding standards, the surface of the weld ( Can inside and outside) should be gentle, uniform, not
