焊接要求 Welding Requirement
焊接之前必须除去预加工边的锈蚀,油污,灰尘,潮湿等。
Welding should be done after removing the rust, oil, dust, moisture etc.
每道焊层必须用钢丝刷清理打磨干净。
Each layer should be removed slag by wire brush and grinding.
如果坡口用碳弧气刨开设,坡口处的碳迹必须打磨干净。
If groove is air-arc gouged, grind surface of groove to smooth and to remove all trace of carbon.
电焊条须经烘干处理(),未经烘干的焊条不得使用。
Electrode should be dried as per section and should not be used without drying.
手工焊时焊条的摆动幅度应小于所用焊条直径的3倍。
Wide of weaving to be limited to less than three times of used electrode diameter.
