Entering Sanfu Tian, the outdoor Jinan is unbearable. Employees of Jinan Working Section are still under the scorching sun, carrying out a series of operations such as rail polishing, replacement of joint splints, and equipment inspections to ensure that the railway equipment is stable and ensured in order to ensure the safety and order of transportation.

"Our welding repair zone is a work zone in charge of welding work. Most of the time, it works under such high temperature and hot weather." Chen Shuchao, a member of the comprehensive maintenance workshop welding work zone of Jinan Working Section, told reporters Most of them are young men of the 90s. They work ordinary and boring, but they are indispensable for railway transportation. The reporter saw at the scene that due to the hot and hot weather and the high operating temperature, the clothes of the employees of the labor section would be completely soaked by sweat shortly after work, and the sweat dripped along the cheeks. In order to avoid heat stroke dehydration, they will carry a two -liter bucket with two liters. Usually a sunroof operation has not been completed, and the bucket basically meets.

Sometimes the welding location is far from the highway, and the tool can only be transported to the welding site with a cart.

The equipment is large and small, and the workers are sweating to the welding location.

The work responsibilities of the welding work area are to prevent safety accidents, so that the rails are constantly manually maintained. Once the rail disease is found, they need to be reported to the diseased track, and they are responsible for welding the "healthy" rails. And this welding is not a simple operation, the key is that it must be "seamless".

Workers are cutting off the track that needs to be replaced

According to Chen Shuchao, there are more than a dozen steps in the entire welding operation process. From the beginning of the preparation to the end of the rail dehumidification, the sand mold sealing box is installed, followed by the preheating reaction to polish until the deduction is resumed. The entire welding rail operation was completed. "The welding rail process is actually the oxidation reaction in the chemistry. The iron is replaced with aluminum from the three iron dioxide, and the rail cracks reserved by the exchanged iron are welded to achieve the" none of the entire line. Slimination '. "Although a few words, Chen Shuchao introduced the process of" seamless "welding to reporters, but in fact, it requires more complicated details and a lot of experience in cooked cleverness.

Place the new rail to an accurate position, this is a fine job

After the "seamless" welding rail operation is over, the rail temperature is required to drop below 300 degrees before the release of the train is allowed. In other words, the entire welding rail operation process is accompanied by high temperature, and the chemical reaction of welds produces huge calories. Their operating environment of the year and four seasons is a temperature range that ordinary people cannot imagine. In addition, although each step is not particularly precise, the entire operation time is strictly fixed. This requires the cooperation of all employees to be strictly seamless in order to make the final "seamless" welding smoothly.
