For rail transport, it is essential that the track systems are secure and reliable. This is why we place the utmost importance on the quality of our products and develop these on a continual basis.
As part of this, we have enhanced the Thermit® welding process for grooved rails. We have therefore also adapted it to the requirements of EN 16771 (aluminothermic welding of grooved rails) and certified it pursuant to this standard.
In May we started with the introduction of the certified Thermit® SRZ(EN) welding process. This replaces the existing Thermit® SRZ process.
Thermit® SRZ(EN) differs from the existing SRZ process due to:
The Thermit® SRZ L50 flangewidth/flat-bottom rail and Thermit® SRZ L75 process variants will remain unchanged. The specified use of Thermit® Plus portions for grooved rail steel grades from R260 will also remain in place. Track tests have shown that weld metal dents can be avoided with this portion variant. These Thermit® portions can also be used to safely weld higher-strength grooved rail steel grades, which undergo higher stresses during installation. In addition, Smartweld Jet preheating has a positive effect on ultra-high-strength grooved rail grades from rail grade R340GHT. For the reliable execution of the preheating process, ensuring the consistently high quality of your Thermit® weld, preheating with the Smartweld Jet is recommended for all grades and profiles.
