【摘要】 针对目前焊轨生产中采用К型焊机焊接PD36 0kg/m钢轨 ,接头灰斑缺陷多 ,性能难以达到部颁标准要求的工程实际问题 ,从钢轨加速烧化阶段的高频数据入手 ,详细分析了这些数据的特征与接头质量之间的关系 ,找出了钢轨闪光焊的过程特征 ,为建立完善的焊接质量在线监控体系提供了依据 .更多还原

【Abstract】 Aiming at the problem that the use of К190Лк welding machines for welding PD 3 60 kg/m rail makes the quality of joints not satisfy the TB/T1632-91 standard because of the existence of grey spots in welding joints, the relationship betw een the quality of rail joints and the eigenvalue of high frequency data at the acceleration stage of rail smelting is analyzed, and the process eigenvalue of r ail flash welding is obtained. The research contributes to establishing of the o n-line control system of welding quality.更多还原
