A new breakthrough in the welding construction of urban rail transit is realized.
After welding, the track is smooth and seamless without any trace of welding. Today, we are going to see the welding process of the grooved rail aluminum welding.
Multi-angle groove rail
Groove rail is the special rail of urban track, which is the most difficult to roll in rail.Compared with the normal rail, the grooved rail has an asymmetric slot, which is complex in shape and difficult to roll, and has the reputation of "king of the rail".
