impulse welding

impulse welding

[′im‚pəls ′weld·iŋ]
(engineering)
A welding process in which two layers of thermoplastic film are heated and fused to form a welded seam by clamping them together in close contact with a shielded electric heating element.

Useful results for temperature development were obtained in cases of high absorption constants by setting up an analytical model by analogy to single-sided heat impulse welding. Yet there is no physico-mathematical model considering the different energy conditions for joining parts with various absorption properties.
