The challenge for the project was completing the welds while maintaining the factory-fitted stray current encapsulation/insulation. There was a risk of stray current readings being outside of the permissible values, which could have caused safety issues for the tram line.

Despite these challenges, Welding S&C Unit successfully completed all the required welds without removing the factory-fitted encapsulation system. This achievement ensured that the safety of the tram line was not compromised, and the project was completed on time.

Another challenge faced during the project was limited space to complete the required profile grinding post welding. However, the team was able to overcome this by utilizing their expertise and experience to perform the necessary grinding, ensuring that the finished welds met the required standards.

Overall, the project was a success, and Welding S&C Unit proved their ability to complete welding works to a high standard, even in challenging circumstances. The team’s dedication and expertise were instrumental in ensuring that the tram line extension was completed safely and on time.
