RESEARCH-AND-PRODUCTION ENTERPRISE ROBOTIC SYSTEM FOR CENTER SILLS WELDING The equipment is designed and manufactured under Tikhvin Freight Car Building Plant order. It is a unique , one-of-a-kind system for robotic submerged arc welding of longitudinal seams of all freight car center sill models. The system allows to perform welding of workpieces in "normal" position as well as in "reverse" position ensuring reverse deflection during welding in order to prevent welding deformations. Robots application allows to perform fast and flexible changeover to different items. In this case the robot...

RESEARCH-AND-PRODUCTION ENTERPRISE STAND FOR AUTOMATIC WELDING OF A CENTER SILL WITH I-BEAM The stand is designed and manufactured under Tikhvin Freight Car Building Plant order. The stand of automatic welding has original design and technology concepts which do not have analogues in railroad car building. It fully operates in automatic mode on assembly and automatic welding of the workpiece. Approved configuration of the stand for automatic welding of center sill to I-beam is typical for all the railroad car building plants, but this stand has distinctive features: 4 -beam centering about...

RESEARCH-AND-PRODUCTION ENTERPRISE MULTIPURPOSE LINE FOR ASSEMBLY AND AUTOMATIC WELDING OF GIRDERS The line is a multipurpose equipment allowing to manufacture 380 - 700 mm high girders of semitrailers. The first position involves girders assembly and their automatic welding from the front, then the item is turned over 1800 with a built-in rotator, and after that welding from the reverse side takes place. Automatic welding is performed by means of traveling gantry plant. Actuation of the gantry and the torches is performed by means of servodrives which ensures travel and positioning...

RESEARCH-AND-PRODUCTION ENTERPRISE LINE FOR ASSEMBLY AND WELDING OF ELECTRIC LOCOMOTIVES SIDE-FRAMES The equipment is manufactured for Novocherkassk Electric Locomotives Plant. This line is multipurpose one - it ensures assembly and welding of sideframes of all produced models of the electric locomotives. The line involves CMT Twin (Fronius, Austria) welding technique. It allowed to reduce occupied area, increase efficiency, minimize deformations after welding. 2 1 Gantry for welding of strips transverse seams 1 – stand for assembly and automatic welding of strips 2 – gantry for welding of...

RESEARCH-AND-PRODUCTION ENTERPRISE LINE FOR VESSELS ASSEMBLY AND AUTOMATIC WELDING This center is multipurpose one and it allows to to localize vessel production on a small area. It ensures output of a wide range of vessels with different diameters with a slight realignment on one plant. The line is equipped with an external clamp which automatically provides sections edges overlapping for welding which significantly decreases assembly labour intensity and ensures quality assembly for automatic welding. Assembled vessel elements are welded automatically with plants for welding of internal...

RESEARCH-AND-PRODUCTION ENTERPRISE PASSENGER CAR ROOF SHEATHING WELDING The equipment is manufactured for Tver Railroad Car Building Works. The stand is unique one and does not have analogues. Welding on this stand is performed in automatic mode without operator's participation, applying laser seam tracking system over the whole length of the workpiece. The stand is multipurpose and flexible one. ROBOTIC CENTER FOR WELDING OF FREIGHT CARS CROSS BEARERS The plant provides for ability to automatically readjust for output of eight types of roof sheathing rapidly If there is a need then it is...

RESEARCH-AND-PRODUCTION ENTERPRISE AUTOMATED CENTER FOR WELDING OF GONDOLA CAR SIDE WALLS ROBOTIC CENTER FOR WELDING OF GONDOLA CARS END WALLS All the operations of clamping and welding of the item are performed automatically, operator just needs to control the welding process and provide loading/unloading of the workpieces. Applying of Festo intellectual pneumatic automation allows to control workpiece assembly accuracy, to inform the worker about deviations, minimizes human factor. After welding from the reverse side the end wall is rotated by 1800 with a built-in rotator and laid on the...
