Abstract:

An electromagnetic induction welding device for isolation sheets has been developed with the aim of labor-saving, greater automation, and improved safety during the installation of isolation sheets in tunnels and other similar structures. This innovative development of the conventional sheet welding system is able to automatically locate welding points, disks through the sheet, heat them by electromagnetic induction, and apply pressure to weld the sheet to heated disks on the primary lining of a tunnel. Use of the device at actual worksites has eliminated a difficult and strenuous job, improved work efficiency considerably, and consequently enhanced the quality of work.
