A modern micro-plasma welding process is used to create secure and permanent connections between metal bellows and stainless steel or steel hubs with reproducible quality. The welded connection meets the highest requirements, especially with regard to absolute freedom from play, high concentricity and maximum torsional rigidity.
In contrast to adhesive bonds, it is absolutely and indefinitely durable even under critical operating conditions (-50 to +300°C, chemicals).
