A range of stud welding equipment and cup head pin systems from Antec Engineering
has successfully resolved a non-sticky issue for Sigma on QR carriages.
The self-stick insulation material originally specified for the new rail carriages was peeling away from the cover of the air-conditioning units. Sigma trialled a number of options that were labour-intensive and costly.
Antec provided a solution that involved the application of cup head pins with stud welding machines for quick and easy installation on the insulation, resolving the problem of the insulation peeling away while saving time on ongoing maintenance and reducing the disruption of trains being out of service.
