与手弧焊相比,其最大的优点是焊缝质量好,焊接速度高。××清大圣科&times ;清大圣科电焊条×清大圣科电焊条设备×清大金桥×清大金桥电焊条设 备×清大圣科气化炉×www.qhsk.cn×清大圣科科技有限公司 ××
焊接时,在焊接区的上面覆盖一层颗粒状焊剂,电弧在焊剂层 下燃烧,将焊丝端部和局部母材熔化,形成焊缝。××清大圣科×清大圣 科电焊条×清大圣科电焊条设备×清大金桥×清大金桥电焊条设备&ti mes;清大圣科气化炉×www.qhsk.cn×清大圣科科技有限公司&tim es;× 在电弧热的作用下,上部分焊剂熔化熔渣并与液态金属发生冶金反应。××清大圣科& times;清大圣科电焊条×清大圣科电焊条设备×清大金桥×清大金 桥电焊条设备×清大圣科气化炉×www.qhsk.cn×清大圣科科 技有限公司××
熔渣浮在金属熔池的表面,一方面可以保 护焊缝金属,防止空气的污染,并与熔化金属产生物理化学反应,改善焊缝金属的万分及性能;另一 方面还可以 使焊缝金属缓慢泠却。××清大圣科×清大圣科电焊条×清 大圣科电焊条设备×清大金桥×清大金桥电焊条设备×清大圣科气化炉& times;www.qhsk.cn×清大圣科科技有限公司×× 埋弧焊可以采用较大的焊接电流。××清大圣科×清大圣科电焊条&ti mes;清大圣科电焊条设备×清大金桥×清大金桥电焊条设备×清大圣 科气化炉×www.qhsk.cn×清大圣科科技有限公司×&tim es;
