球罐由球壳板组对成形,外形简单,多用来储存液化气体,使用压力相对较高。焊接施工是很重要的施工环节,焊接质量好坏对球罐的使用有很大影响,而焊缝分布相对较广,焊接施工历来都备受关注。本文从焊条电弧焊的角度出发,简述了球罐焊接常采用的一般施工过程。 Spherical tank from the ball shell group forming, simple shape, and more used to store liquefied gas, the use of relatively high pressure. Welding construction is a very important construction link, the quality of welding has a great influence on the use of the spherical tank, and the relatively wide distribution of the weld, the welding construction has always been a concern. This article from the arc welding point of view, describes the general construction of the spherical tank welding often used.
