Rail and rail welding quality is closely linked to traffic safety. Because with less pressure welding equipment, welding of low-cost, higher quality welding series advantage in the field of welding and repair of broken rail CWR, has a wider range of applications.Container plateau pressure welding rail cars that YHGP-1200-type pressure welding rail cars, vehicle layout specification, easy to operate, the higher the overall operations of integration; equipped with welding, normalizing a machine, and can automatically, automatic push tumors and many other features of GPW-1200rail pressure welding machine, can be the base or on-site welding.In this thesis, the non-self-propelled rail pulling day pressure welding rail cars for the study, the types of welded rail cars for statistical analysis in different conditions and welding parameters; for type testing, online unit welding, weld line lock head, respectively, according to three different grade quality criteria for quality evaluation. Through research and studies while welding construction site, optimized welded rail car construction work plan, develop and regulate the online unit welding, weld line lock construction techniques.Studies have shown that:1. the construction of welded rail track to pull date for the construction program:first500m long rail line unit welded into1000m, followed by " connected to the Law" section of the construction will be carried out online1000m unit rail welding performed under natural conditions Bleeding lock cylinder, the online unit welding, weld line lock combination of welded rail way construction process to meet the on-site construction of new lines into account a variety of engineering parallel job requirements.2.welding, non-self-propelled rail cars normalizing pressure welding machine of a job in the plateau region welded rail, once passed the type test, good quality fittings.3. By type test, online unit welding, welding of different conditions online locking divided three levels of process parameters standard choice more broadly the third level joint quality standards for judging the quality of judgment, meet T/TB1632" rail welding" standards.4. scene through a single connector rail saws, rust, end mill for rails, welding, normalizing, coarse grinding, fine grinding and other processes, a total of49min, good joint quality; using water welding, normalizing a machine of operations, within three hours of welding three pairs (6) connectors, which the operating efficiency of≤30minutes/welding head.
