Abstract
Disclosed is a burner head capable of securing heat resistance and durability characteristics and improving the quality of machining at the same time, capable of easily and stably machining a material into a complicated shape. A second metal primary material of the iron family having high workability and first metal primary materials of the SUS family having high heat resistance are rolled out. Their side plate ends are butt-welded by laser to form a one-piece metal flat-plate material. A press molding machine is operated to press mold recessed portions of a pair of plate members simultaneously with cutting along a contour line. Then, folding is carried out, and they are closely joined together. A gas passage is formed by a recessed portion of the second metal primary material section. A burner port is formed by a recessed portion of the first metal primary material section.
