摘要
针对采用YHGQ-1200型气压焊轨车在现场焊接过程中钢轨接头出现塌角缺陷的问题,以博小线换轨施工焊接再用轨为例,根据型检过程中与现场实际出现的问题,对钢轨接头塌角缺陷的产生原因进行了分析,归纳总结出钢轨接头塌角缺陷的解决方案。现场实测表明,该方案可以有效地解决钢轨焊接接头塌角的问题,对钢轨焊接具有一定的参考意义。
Aiming at the problem of rail joint collapse defect in the on-site welding process of YHGQ-1200 pneumatic rail car,taking the welding re-use rail of Boxiao line rail change construction welding as an example,according to the problems in the process of type inspection and the actual problems in the field,the causes of rail joint collapse defect are analyzed,and the solutions of rail joint collapse defect are summarized.The field measurement shows that the scheme can effectively solve the problem of collapse angle of rail welded joint,which has certain reference significance for rail welding.
