YSP—15型液化石油气钢瓶制造过程中的环缝焊接工艺,目前国内生产厂家大多采用两层埋弧焊或等离子弧焊封底埋弧焊盖面的焊接方法,这两种方法的焊缝均需两层焊道来完成,故生产效率低、工艺复杂、设备投资大。据此,我们通过改进,采用了单面一次焊接双面成形的埋弧焊工艺,经一年多的施焊表明,该工艺方法,焊接质量优良,达到有关标准要求,并于1985年9月通过了省级技术鉴定。
YSP-15 type liquefied petroleum gas cylinder manufacturing process of girth welding process, the current domestic manufacturers are mostly used two submerged arc welding or plasma arc welding submerged arc welding method of cover, both of the welds are To be completed by two layers of welding, so the production efficiency is low, complex technology, equipment investment. Accordingly, we improved, using a single-sided welding double-sided forming submerged arc welding process, after more than a year of welding shows that the process, the welding quality, meet the standards, and in September 1985 Passed the provincial technical appraisal.
