1. A method of manufacture for a pneumatic deicer boot, comprising:
aligning a non-stretchable fabric layer and a stretchable fabric layer at a welding position;
generating a concentrated laser;
focusing the concentrated laser along a first weld line to laser weld together the stretchable fabric layer and the non-stretchable fabric layer, wherein the first weld line includes a plurality of air passage gaps to assist in even inflation and deflation between adjacent inflatable tubes of a plurality of inflatable tubes; and
focusing the concentrated laser along a second weld line to laser weld together the stretchable fabric layer and the non-stretchable fabric layer, wherein the second weld line includes a plurality of air passage gaps to assist in even inflation and deflation between the adjacent inflatable tubes of the plurality of inflatable tubes, wherein a first gap remains between the stretchable fabric layer and the non-stretchable fabric layer, and wherein the first gap, the first weld line and the second weld line form a first inflatable tube of the plurality of inflatable tubes; and
bonding an installation layer to the non-stretchable fabric layer of the inflatable carcass.
