Ceramic welding parts made of silicon nitride significantly increase service life and enable high levels of precision and greater accuracy over extended periods in nut/projection welding. Metal welding pins often need to be replaced several times a day due to wear and adhering slag, whereas welding guide pins made of silicon nitride ceramics only need to be replaced about once a month.
