在一些文献中都提到散布分段焊接可以减小焊接内应力及变形。此外,在很多厂矿中,这种方法也有较广泛的应用,但是这种焊接方法的采用或推荐往往带有很大盲目性,缺乏足够的据根和具体的分析;好像不论在任何条件下,不论用任何方法,只要把长焊徒分成一些短段来分别焊接,都可以减小焊接变形和内应力。这样不加分析的采用散布分段焊接法,不但降低了生产率,造成了工作上的不便,限制了自动焊的广泛应用,而且在很多情况下难于达到预期的目的, In some literatures, it is mentioned that the segmented welding can reduce the welding internal stress and deformation. In addition, this method is also more widely used in many factories and mines, but the adoption or recommendation of this welding method often has great blindness and lacks adequate rooting and concrete analysis. It seems that under any conditions, Regardless of any method, as long as the long welding is divided into short segments to be welded separately, can reduce the welding deformation and internal stress. This unscreened segmented welding method, not only reduces productivity, resulting in work inconvenience, limiting the widespread use of automatic welding, and in many cases is difficult to achieve the desired purpose,
