The device for welding two fusible polymer parts obtained from heating sheet in the form of elongated object, sheath and band knitted by resistive thread coated with insulating varnish, where the heating sheet has irregular meshes in a parallelogram form of which the dimensions are 1.5x3 to 2.5x4.5 mm 2>. The heating sheet is electrically supplied by an automatic voltage regulator and resistant to short circuits. The heating sheet is obtained from resistive thread with a diameter of 0.2-0.3 mm, and is covered with the varnish. The device for welding two fusible polymer parts obtained from heating sheet in the form of elongated object, sheath and band knitted by resistive thread coated with insulating varnish, where the heating sheet has irregular meshes in a parallelogram form of which the dimensions are 1.5x3 to 2.5x4.5 mm 2>. The heating sheet is electrically supplied by an automatic voltage regulator and resistant to short circuits. The heating sheet is obtained from resistive thread with a diameter of 0.2-0.3 mm, and is covered with the varnish of which a melting point is chosen to melt the varnish at a predetermined temperature causing short circuit with the heating sheet. An independent claim is included for a process of welding two fusible polymer parts. |
