9 Plasser and Vaia radio-electric welding machines.
The best machines available on the market, capable of work on tracks and/or road rails. They produce welds which improve the geometric stability of the track structure without giving rise to points of fragility that the change in metallurgical properties of the rail near the welds otherwise tends to entail.
A new weld standard
The bolted joints of rails have always been a major cause of discontinuity and, as a result, of maintenance requirements.
The introduction of welded rails improved the geometric stability of the track, but the localised modification of the metallurgical structure of the rail near the weld was a problem for many years, causing loss of fluidity, irregularities, undulations and - over time - damage to the fixtures and sleepers.
The Plasser K355 APT welding machine, in the 1970s, introduced the new spark welding technology to set new quality, performance and durability standards..
The welding sequence can be programmed in relation to the type and profile of the rail and is error-free.
The welding head incorporates a cutting device to immediately remove excess weld bead.
All welding head movements are performed with hydrostatic drive.
The machine can produce a detailed graphical report of each welding sequence by recording all parameters. This provides an immediate assessment of weld quality and detailed tracking of the work performed.
