上海锅炉厂完成了容积为2000米~3的球形贮罐的制造任务.该球罐内径为15.7米,球壳分别由25毫米和28毫米的16 MnR 钢板拼焊制成。本文介绍球罐的焊接情况,内容包括焊前的准备、焊接过程和焊后的检验、补焊等问题。最后,作者根据球罐焊接的实践,还对目前使用的规范提出了自己的看法,可供有关单位参考。 The Shanghai Boiler Works completed the manufacturing of a spherical tank with a capacity of 2000-3.0, with an inner diameter of 15.7 meters and a spherical shell made of 25-mm and 28-mm 16 MnR steel plates, respectively. This article describes the ball tank welding situation, including the preparation before welding, welding process and welding inspection, welding and other issues. Finally, according to the practice of the spherical tank welding, the author also put forward his own views on the currently used norms for the reference of the relevant units.
