Abstract:
A process for the laminar bonding of material comprising the steps of:providing a carrier material selected from a group comprising strips, foils or sheets; applying at least one electroconductive powder coat of powder particles onto the carrier material; and exposing said at least one electroconductive powder coat to a magnetic alternating field in the frequency range from ca. 10 kHz to 120 MHz to thereby generate in said at least one electroconductive powder coat an induction current having an energy density that the points of contact of the powder particles among themselves and with the carrier material are fused together at a temperature above the sintering temperature of the powder particles, wherein said generated induction current has an energy density and duration that the core zones of the powder particles do not reach a temperature at which the properties of the powder particles change.
