The impulse welding
system and the dimensions of the samples used in this study for welding the PLA films are detailed in Fig.
That is why Chase also offers Hot Air, Impulse Welding
, RF Welding, Heat Sealing, CO2
In impulse welding
, one or more electrically heated bars/elements are pressed against the surfaces of the films to be welded until the films melt and bond at the faying surfaces.
Chase Machine & Engineering is the world leader in the design and manufacture of continuous-web machinery, employing ultrasonics, impulse welding
, adhesive, hot air and laser technologies.
For example, in the case of impulse welding
, local collapse or sample displacement occurs, however with laser microwelding, this deformation is restricted by joint geometry and is controlled by local thermal expansion (15).
In this article, Part 1, coupled squeeze flow and healing models are developed and verified with experimental work based on standard industrial welding techniques, such as impulse welding
using thermal histories that were experimentally measured.
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.
