rail welding meaning in English
钢轨焊接
Examples
- The rail welding technique of high - speed railway
高速铁路钢轨焊接技术 - The alloy steel rail , which is used widely in the railway engineering in our country , has poor weldability although it has high intensity and excellent wearing capacity , and the means of quality control in rail welding equipment is still not perfect , which leads to the hidden safety trouble in railway
目前，我国铁路轨道工程中应用的多种合金钢轨，强度高，耐磨性好，但可焊性较差，而现有焊轨装备质量监控手段尚不完善，使线路存在安全隐患。 - Aiming at the problems of the k190jik rail welding machine , that the parameter modification is difficult , the welding process is not enough stability and the welding machine has no on - line diagnosis function , in this paper , the control system of the welding machine was promoted completely adopting the fx2n - 64mr programmable logic controller and the pcl - 1800 data acquisition card , the das ( data acquisition system ) was set up by using labview and visual basic software , the functions of welding voltage stabilizing and adjusting , current controlling and intellectual modification was improved , welding quality diagnosis system was built up , and the assembling and debugging of the control system was completed , including the process experiments
本文针对k190jik钢轨焊机控制系统存在参数修改困难、焊接过程不够稳定、无焊接质量在线诊断功能等问题，采用日本三菱公司fx2n - 64mr可编程序控制器、研华工控pcl ? 1800数据采集卡等为核心控制部件，对焊机的整机控制系统进行了全面升级。运用软件labview和vb开发了数据采集系统，完善了焊接稳压、调压、电流恒值控制与智能调节功能，利用vb建立了焊接质量在线诊断系统，并完成了系统组装调试与工艺试验研究工作。 - With an introduction of the influences of the final quality of rail aluminothermic welding , such as : the quality of welding kits ( esp . the portion ) , the result of pre - heating , the welding operation and the level of operators etc . , this paper analyzes some problems when rail welding under special conditions
摘要介绍了焊接材料质量、预热效果、操作人员水平等因素对钢轨铝热焊接接头质量的影响，以及几何误差不同、轨头宽度不等、寒冷气候等特殊条件下进行铝热焊接应注意的问题。 - According to the engineering experiences obtained from the laying of a jointless track of high - speed communication line - line 3 in dalian city , this paper introduces in general the laying technology , particularly the long rail welding , the construction site welding , seamless track spreading and trak controller laying , and discusses problems often occuring in long rail wedling and seamless track laying
