由于我国工业的迅速发展,要求工业各领域广泛地采用自动焊和半自动焊。同时由于技术不断地进展,对产品质量要求更为严格,从而对焊缝质量要求更高。小口径容器,由于内径较小内部施焊困难,目前往往采用特殊的施焊方式,如内垫铜垫或焊剂的单面焊双面成形,内放钢衬垫的单面手工焊。这些措施虽解决一定的问题,但劳动强度和劳动生产率是不高的,焊接质量的可靠性也不强。特别是焊前准备工
Due to the rapid development of China’s industry, it is required to widely adopt automatic welding and semi-automatic welding in all fields of industry. At the same time as the technology continues to progress, more stringent product quality requirements, which require higher weld quality. Small-diameter containers, due to the internal diameter of the smaller internal welding difficulties, the current often use special welding methods, such as the inner pad copper pad or flux single-sided welding double-sided forming, steel pad placed within the single-sided manual welding. Although these measures to solve certain problems, but labor intensity and labor productivity is not high, the reliability of welding quality is not strong. In particular, pre-welding workers
