product features:

1.realizes the core function of "parking on the current line and operating on the current and adjacent lines". it can complete the rail welding operations on the current line and the adjacent lines within a radius of 7m centered on the current line without the need for equipment and vehicle line transfer.

2.integrates the welding and normalizing function in one to achieve continuous and efficient processing of welded joint quality.

3.capable of performing rail welding operations without power failure of the catenary.

4.adapts to the operating environment of straight and curved sections (including sections with a maximum super-elevation of 175mm).

5.can realize flash welding and normalizing operations of switches by switching the special switch welding head.
