摘要
目的研究某产品摩擦焊的工艺性能。方法研究了超高强钢45CrNiMo1VA钢在不同摩擦焊接工艺参数下的接头组织与性能,以及在不同热处理回火温度下对焊接接头强度的影响。结果在合适的工艺参数下,45CrNiMo1VA钢的高韧性可以有效保证焊接接头韧性,满足产品高指标的要求,使焊接接头组织具有良好的组织性能,焊后热处理工艺的正确确定是保证焊缝组织性能与母材组织性能的重要保证。结论试验证明超高强钢(45CrNiMo1VA)完全可以应用于摩擦焊生产中,并能获得理想的性能指标。
Objective To study the friction welding process of a product. Methods The joint structure and properties of ultra- high- strength steel 45CrNiMo1VA under different technological parameters of friction welding,as well as the effects of different tempering temperatures in heat treatment on the strength of welded joint were studied. Results The results showed that the high toughness of 45CrNiMo1VA steel could effectively guarantee the toughness of welded joint,which met the high performance requirements of products,and improved the performance of the welded joint. The correct determination of heat treatment after welding was the important guarantee for the performance of weld and parent metal structure.Conclusion Trials showed that ultra- high- strength steel( 45CrNiMo1VA) could be used in the friction welding production with ideal performance.
