稀土钻永磁机磁盘可采用两种材料焊接。对于焊后环焊缝存在小气孔和未焊合现象,利用磁盘的静强度考核办法已说明不了问题,本文利用现代测试技术对其构件进行了断裂分析,其成果已应用到生产实践中。
Rare earth drilling permanent magnet machine can be used two kinds of materials welding. There are no stomatal phenomena and unsoldered phenomena in the welding seam girth weld. The method of checking the static strength of the disc can not explain the problem. In this paper, the fracture analysis of its components is carried out by modern testing technology. The results have been applied to the production practice.
