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

And generally these welding parts made of silicon nitride ceramic only require replacement when damaged by mechanical force. This not only provides more economical production thanks to a reduction in costs, but also makes the entire process more robust, which in turn results in consistently high product quality.
