Welding rails is a very heavy job, have strict requirements and standards, high technical requirements for welding, the following small series is to introduce the rail alignment and pouring in the process of welding the rail.

Alignment of rail ends, rail seam adjustment: measured on both sides of the rail head and the rail bottom, the rail joint must meet 25mm±2mm. Sharp point setting: for type III concrete pillows, the unit point is 1.6mm, when welding, the tip point of the lock welding is 1.9mm, that is the 1m ruler is placed in the middle of the rail joint, when the state is horizontal, the gap value at both ends. Horizontal alignment: use the ruler to closely adhere to the rail head, rail waist and rail bottom of the rail, under normal circumstances, it is necessary to make three levels of close stickers for horizontal alignment. In practice, the first consideration is to focus on the working side of the rail head and the waist of the rail.

Check flux ignition casting. Open the solder pack inspection while preheating(not too early), don’t get wet, no damage, no debris in the sputm. Insert high temperature matches into the solder and cover the lid. When the preheating is over, remove the preheater, place the split plug in the inlet at the top of the sand mold, and place the disposable crucible in the center of the sand mold. Ignite a high-temperature match and insert it into the flux, the depth is 25mm, and the lid is covered, at this point, the flux begins to react and poir. When the waste slag stops flowing, press the stopwatch to start recording.
