Innovacera manufactures Silicon Nitride (Si3N4) Ceramic weld location and control pins for use in resistance welding. These are used in the metal forming industry to allow precise welding of nuts to sheet metal.
Due to ceramic’s high hardness and durability, metal can’t compete with it in insulating properties, resistance to temperature changes, and minimal wear. Another advantage of using ceramics as centering pins is their smooth polished surface, which prevents welding spatter from adhering. However, when welding pins made of commonly used zirconia ceramics, the service life does face a limit. This material also cannot withstand the currents in projection welding and the required 800°C operating temperature over time, so it wears out. And centering standard molds made of silicon nitride ceramic is a good choice.
Silicon nitride ceramic weld location pins have the following advantages:
1.High-temperature stability: Silicon nitride ceramics can maintain stability in high-temperature environments, have excellent heat resistance, and can withstand thermal stress and thermal cycles during high-temperature soldering.
2.Corrosion resistance: Silicon nitride ceramics have excellent corrosion resistance to common corrosive media such as acid and alkali.
3.High hardness and wear resistance: Silicon nitride ceramics have high hardness and wear resistance, which can keep their shape and geometry stable for a long time during the welding process.
4.High precision: Silicon nitride ceramics have excellent dimensional and mechanical stability and are suitable for applications requiring high-precision positioning in welding processes.
Therefore, silicon nitride ceramic welding location pins are an ideal material for positioning and support needs during welding.
