Abstract
A method for continuously producing high-strength welded composite panels from thermoformable material facings and expanded thermoformable material cores comprising the steps of: simultaneously feeding facing sheets and core into a welder that has automated feed rollers; heating the lower side of the top face and the upper side of the lower face simultaneously with both faces of the inner core of expanded thermoformable material; continuing to heat them to 100-400.degree. C. until the surfaces reach the initial melt and/or hot tack temperature of the materials; pressing the heated faces together against the heated surface of the core material to consolidate the composite structure; and allowing the materials to cool while under pressure and continuing to move forward in the engaged roller mechanism until the entire panel has been welded and is dimensionally stable.
