addtime:2025-04-17click:237


On April 17th, a 20-member observation team from the Chengdu Railway Bureau headed to the construction site of the Panxing (Panxian - Xingren) Railway Project to conduct an on-site inspection of the rail welding operations carried out by Aigre's turnout flash butt welding machine. The company's exceptional rail welding technology garnered high praise from the Chengdu Railway Bureau.

At the observation site, Aigre's technical experts proficiently operated the turnout flash butt welding machine for rail welding. Upon completion of the welding process, it was measured that the consumption of the welded rail was precisely controlled at 39.8mm, which matched the actual displacement data measured on-site. The observers from the Chengdu Railway Bureau gave high marks to both the post-welding appearance quality and the precise displacement control.

This recognition from the Chengdu Railway Bureau is a strong affirmation of Aigre's turnout flash butt welding machine technology and welding process. In the future, the company will continue to intensify its efforts in technological research and development, enhance product quality and service standards, and contribute more significantly to the cause of railway construction.
