焊接是球罐建造中的关键工序,其焊接质量好坏往往决定整个球罐的建造质量。然而,焊接质量在一定程度上又取决于焊接方法。为适应球罐建设的需要,经反复试验研究,从1976年我们就逐步采用了手工焊与自动焊相结合的方法焊接球罐,至今已焊接了19台容积为400M~3的球罐,效果良好。 Welding is the key process in the construction of a spherical tank. The quality of its welding usually determines the construction quality of the entire tank. However, the quality of the weld depends to some extent on the welding method. In order to meet the needs of the construction of the spherical tank, after repeated experimental studies, from 1976 we gradually adopted a combination of manual welding and automatic welding method of welding the spherical tank, so far has been welded 19 capacity of 400M ~ 3 spherical tank, the effect good.
