Thermit® News December 2021
Process for welding on extreme inclines
Peak Tram Hong Kong is a funicular railway on Hong Kong Island with an incline of up to 48%. Renovating these rails is therefore particularly challenging.
The tracks of the funicular railway were completely renovated this year. Our client was tasked with executing the aluminothermic welds. The challenge of these welds lies in the incline of the rails, which is extreme in some parts.
Elektro-Thermit supplied the welding materials required and the necessary equipment. Thermit® portions, casting moulds and mould shoes were adapted for this. Various test welds were performed and parameters and components of the process optimised at the same time. The last adaptations were made under the actual conditions on site.
Since then, all the welds have been straightened — and everything is back on track! The Smartweld Jet was used to preheat the Thermit® weld. The jet is particularly well-suited to difficult terrains and guarantees that the preheating operation is executed safely.

Supply of welding kits and equipment
Elektro-Thermit delivers welding materials for the modernisation of the railway line.
The Egyptian National Railway project includes the modernisation of the stretches from Zagazig to Abu Kebir (north of Cairo) and from Benha to Port Said, a strategic port at the northern end of the Suez Canal in the Mediterranean Sea. Elektro-Thermit supplied welding kits for the maintenance operations on the track superstructure last year and another delivery is currently underway.
Representatives of the Egyptian National Railway and the client accepted the welds (Factory Assurance Test) at the start of November. The requirements for weld acceptance were very high. In addition to the standard evaluations, additional tests stipulated by the Egyptian Railway were also administered.
The Egyptian National Railway and the client were completely satisfied, with the welds meeting all their requirements.
Optimisation of the portion bag
We have improved the properties of the Thermit® portion bag.
To reliably record the data for the Thermit® weld in the Smartweld app, a data matrix code in accordance with the GS1 standard is also printed on the bag label. This will replace the barcode in the future. This will increase reliability when scanning the Thermit® portion and recording the necessary welding data in the app.
In addition, to attach the data matrix code, improvements have been made to the weld seams and their positioning in the bag. The longitudinal seam has been converted to a side seam and the ventilation has been incorporated into the transverse seam. These changes mean that significantly less material is wasted. The film of the bag remains unchanged and will continue to ensure that Thermit® portions can be stored and transported safely.
