The invention provides a method for producing composite cooking tool, and relative method, for resolving the problems as low
thermal efficiency, long cooking time and short service life. The inventive method comprises that A, producing body of cooling tool as a,
material selection, cold rolling, b, washing,
drying, c, roller pressing, d, drawing, B, returning bottom as a, washing,
drying, b, thermally
forging or solder
welding, c, surface treatment. The inventive composite cooking tool comprises a body and a bottom plate, wherein the bottom plate has welded
metal plate and
metal sheets from inner to outer via thermal
forging or solder
welding, the body has two or three
metal layers welded via thermal
forging or solder
welding, and the body and the bottom plate are welded together via thermal forging or solder welding. The invention has simple process, low cost, uniform heated and long service life.
