Welding Foamed Plastic Boards by Heat Radiation Using a Thin Metal Strip Heater

Abstract

This paper shows a new method of welding foamed plastic boards by heat radiation. In this method, we use a thin metal strip rather than a nichrome wire to produce powerful heat radiation by electric current. This paper first describes the background of this invention and a practical way of implementation, then makes consideration on some factors that will reduce the life of heaters.
