Problems with welding of new and old rail joints

The train is an important means of transportation now, brought great convenience to our trip, the train is on the track, and the rail is the main component of the train railway track, because the rails are under the pressure of the train for a long time, the rail will be damaged, can be repaired for lighter wear, but the serious must be replaced, at this time, we have to face the welding problem of the new and old rails. The breakage, dimensional change and maintenance work of the joint zone track are much more serious than other parts.

1?  The irregularity at the rail joint is the main cause of the rail problem, the reason fot the irregulatity of the rail is that the rail joint bolt has insufficient torque or is not tightened in time, or the hard bend at the end of the rail will increase the structural irregularity of the rail joint.

2?  The rail joint is different from the elasticity of the rail at other parts, the greater flexibility at the rail joints will accelerate the development of irregularities.

3?  In addition, the improper maintenance of rails can also cause the development of joint diseases.

To solve the problem of new and old rail joints, it is necessary to keep the steel rail bed full, strengthen the rail joints firmly, this is the premise to prevent problems, also lock the rails to prevent crawling, adjust large rail seams in time, reduce the impact of the wheel on the joint, reduce unnecessary wear on rails and joint parts.
