Using a modern micro-plasma welding process, secure and permanent connections between metal bellows and stainless steel or steel hubs are created 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 connections, it is absolutely and indefinitely durable even under critical operating conditions (-50 to + 300 ° C, chemicals).
