重力焊是采用高效率铁粉焊条和专用重力焊架子进行平角按焊缝的焊接方法。它具有设备简单,生产率高,操作方便,容易推广,能减轻劳动强度等很多独特优点。一、结503铁高效率铁粉焊条重力焊的目的是为了达到高效率的焊接效果,因此,重力焊宜用直径较大和长度较长的焊条。由此而带来了焊条后段容易发红和焊缝尾部出现气孔的现象。另外,重力焊时不能借助于焊工手势来得到良好的成形,所以重力
Gravimetric welding is the use of high-efficiency iron powder electrode and a dedicated gravity welding shelf welding angle welding method. It has many unique advantages of simple equipment, high productivity, easy operation, easy to promote, reduce labor intensity and so on. First, the end of 503 high iron powder electrode efficiency of the purpose of gravity welding is to achieve high efficiency of the welding effect, therefore, gravity welding should use larger diameter and length of the electrode. As a result, the posterior segment of the electrode is prone to redness and stomata appear at the tail of the weld. In addition, gravity welding can not get good shape by means of welder gesture, so gravity
