摘要
介绍皮下气孔常见特征;对产生皮下气孔的形成机理进行分析;结合生产实践提出了消除皮下气孔缺陷的措施,包括减少气源和改善排气。
The general morphology features of pinhole defect was described;some view points on the formation mechanism of pinhole was proposed.Based on production practice,the measures to eliminate pinhole were suggested including controlling gas source and improving venting.
