研究了电磁纯铁+不锈钢异种金属摩擦焊接头的成分、组织和性能以及对焊件轴向尺寸控制技术。 结果表明,摩擦焊接头具有良好的组织和性能;隔磁体轴向尺寸偏差可以控制在±0.25mm。
The composition, microstructure and properties of electromagnetic pure iron + stainless steel dissimilar metal friction welding joint and the axial dimension control of the weldment were studied. The results show that the friction welded joint has good microstructure and properties. The deviation of the axial dimension of the magnet can be controlled within ± 0.25mm.
