Whilst every vehicle is different, the same can be said of the body shell. The bodyshop is a highly automated process that has to be matched to the individual requirements of every series. This is also where the "pace" is set for all other manufacturing steps. High system availability is therefore an absolute necessity.
Plant shutdowns in bodyshop are like "heart failure" – in just a short time horrendous costs result and the entire production line can come to a standstill. That’s why minimising this worst case scenario is essential. Our products provide very useful support in this respect. They comply with even more stringent quality demands than demanded and provide reliability for a smooth production process.
Today's car body manufacturers still use resistance spot welding as a
principal joining process. A modern car body therefore sometimes has more than 5,000 welding points, and a high volume
model requires about 800 welding controls. For all these systems a high level of machine availability is essential,
and the circuit-breaker is a key component in the welding control system.
Our NZM series circuit-breakers have earned a well established reputation over several years in the automotive production field, as well as with international end customers and major machine suppliers.
The combination of industrial robots and welding guns are used in the highly automated resistance welding process. Whilst industrial robots have achieved a high degree of technological maturity, welding tongs guns are experiencing a technological breakthrough: servo-drive tongs are gradually coming into their own. Optimum and flexible control of the welding tongs guns is guaranteed by the XC200 modular PLC.
