摘要: 銑邊工藝被廣泛用于螺旋縫埋弧焊管生產(chǎn),但控制不好會(huì)導(dǎo)致焊管出現(xiàn)焊偏、未焊透等缺陷。結(jié)合銑邊機(jī)的結(jié)構(gòu)及工作原理,分析了常見的銑邊缺陷形成原因及其對(duì)鋼管質(zhì)量的影響,提出了防止銑邊缺陷產(chǎn)生的措施。Abstract: The edge milling process is widely used for manufacture of SSAW pipes. However,in case that proper control is not ensured,defects like welding misalignment or non-through-welding may be caused. The causes for common defects as occurring in edge-milling operation,and the influence thereby on pipe quality are analyzed,taking the structure of the edge milling machine and its working principle into account. Accordingly,preventative actions against the said defects are proposed.
