Rail Welding

Modern handling equipment require a smooth and continuous rail track. Consequently, rails must be butt-welded to avoid shocks at joints, as well as damage to wheels and other mechanical parts.

The geometry of DIN 536/1 type rails is such that it prevents any other technique for joining the rails.

Practically, two crane rail welding methods are used, on the ground or at height :

  • Enclosed arc using electrodes.
  • Alumino-thermic welding.

Enclosed arc welding

  • Technology :
  • The void between the ends of the rail is filled with a continuous layer of fillet welds.

  • Equipment :
  • – permanent basic equipment : material for adjustment and preheating, set of electrolytic copper blocks, power transformer, grinding equipment.
    – consumables : specially adapted electrodes, heat insulation plates to protect the pad.

  • Implementation :
  • – the technique requires qualified rail welders.
    – welding instructions available.

Alumino-thermic welding

  • Technology
  • The steel obtained by combining iron oxide with aluminum is cast at over 2000°C in a refractory mould matching the rail profile.

  • Equipment :
  • – permanent basic equipment : material for adjustment, mould fixing, preheating, casting and finishing off.
    – consumables : mould adapted to the rail profile, welding charge and igniter.

  • Implementation:
  • – this technique gives excellent results, and is independent of atmospheric and operational conditions.
    – the implementation of this technique requires qualified welders. GANTREX® can provide you with the necessary training and qualification of your welders, or carry out the welding operation.
    – welding instructions available.

Flash Butt Welding (In North America Flash Butt Welding of crane rail is available.)
