Line for assembly and welding of electric locomotives side-frames

This line is multipurpose one – it ensures assembly and welding of side- frames 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.

1.  stand for assembly and automatic welding of strips;5. stand for channel bars mounting, side- frames automatic tack welding and welding;
2. gantry for welding of transverse seams and strips;6. ventilation equipment;
3. gantry for automatic tack welding of channel bars;7. welding equipment.
4. gantry for automatic welding of longitudinal seams;
