Service Live of Welding Elektrodes at Resistance Welding of Zinc Coated Steels with NIT Layer

Popis výsledku v původním jazyce

In the automotive industry, sheets are coated for protection against corrosion and oxidation during forming. This coating may deteriorate the weldability of steel sheets and shorten the life of welding electrodes. Currently, new tips of coatings are used, e.g. coatings based on Al-Si or NIT (New Inorganic Treatment). The contribution deals with the influence of the NIT layer on weldability and electrode lifetime. Electrode life tests were performed according to EN ISO 8166. Steels HX180BD coated HDG (Hot Dip Galvanized) and coated steel HDG + NIT was used as the base material. The results showed that the NIT layer does not particularly affect the service life of the electrodes. On the other hand, when welding HDG + NIT coated sheets, a longer service life (about 600 weld points) was achieved than welding of HDG-coated sheets.
