Product detail
Silicon nitride (Si3N4) ceramic welding pins are specifically designed as location pins for projection welding, facilitating precise welding of nuts to sheet metals. These solid ceramic pins are constructed from ultra-hard silicon nitride ceramic material, featuring smooth surfaces and precise dimensions. The outstanding properties of high hardness, high strength, and excellent wear resistance make silicon nitride ceramic the toughest material for ceramic welding pins.
One of the key advantages of silicon nitride welding pins is their electrical insulation. This eliminates any unwanted current and prevents sparks between the ceramic pin and the workpiece. Additionally, it reduces the need for slag removal during the welding process. The remarkable wear resistance and high fracture toughness of silicon nitride ceramic ensure long-lasting and accurate positioning of the workpiece. As a result, the welded workpieces maintain exceptional quality and high yield, reducing the frequency of locating pin replacement and enhancing overall production efficiency.
