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.

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.
They were selected because they represent materials that will probably be used in MEMS and microfluidic applications, so the results from the impulse welding could be used to analyze microwelds in Part 2.
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.
