Pre-emptive build-up welding for tram rail<br />
For rail with radii < 250 m (up to min. 17m).<br />
Grooved rail of the 700+ Vanadium (685-835 N/mm 2 ) quality.<br />
Increasing the hardness up to approximatively �500 HB (comparable to the 900A-rail), which<br />
considerably reduces the lateral wear of rail in curves.<br />
Initial welding process in the workshop (even before instalment).<br />
Build-up welding is possible up to 8 times (on site).<br />
Steel quality Materials for build-up welding (on site) :<br />
C 0.20 - 0.30 % 0.07<br />
Mn 1.20 – 1.50 % 7<br />
Si 0.20 – 0.30 % 0.9<br />
