Abstract: A composite-type temperature raising and control integrated heating element and a temperature control method are provided. The heating element includes a heating body, which is integrated by welding two different conductive materials at a welding point. The heating element is not provided with a temperature measuring element other than the heating body. The heating body of the temperature raising and control integrated heating element is formed by welding two conductive materials. When a high voltage is applied, the two conductive materials serve as the heating body to generate heat. When the supply of the voltage is stopped, the two conductive materials serve as a thermocouple temperature measuring sensor to measure the temperature of the heating element. Compared to existing heating elements, the temperature measuring sensor is omitted, the fabrication process of the heating element is simplified, and the performance of the heating element is improved.
