Precautions during rail track welding

Apr 13, 2020
*  When welding each layer, especially when welding each layer of the rail bottom, it is best to use a single electrode to complete the welding at one time, avoiding the use of welding electrodes to interrupt the arc in the middle, the two welding layers direction should be opposite;
* The welding work of each rail joint should be carried out continuously to keep the rail end welding at a higher temperature (300 ℃ ~ 350 ℃);
* After welding, when the stress-relieving heat treatment has not been cooled, it must be protected from rain, etc .;
* The hot red copper plate can be removed and cooled with water so that it can be reused next time.
