Welding isn’t just for aircraft carriers anymore. The U.S. Navy could be turning to ultrasonic welding to make its uniforms lighter, stronger and cheaper. And if the project by a Rhode Island company and the Navy Clothing and Textile Research Facility is a success, it could help bring manufacturing back from overseas. Welded seams are created when two pieces of fabric are essentially melted together by sound waves. ¬†They are already used in some clothing that some Americans have in their closets. Propel LLC is trying to figure out how to make the Navy’s expensive parka without stitches, which it currently buys for $190.50 each. It has spent the past year testing welded seams, adhesive techniques and other bonds using a federal grant from the Navy.
