Experience with regard to the welding of nickel alloys in pressure vessel construction - Tips from practice

Ever trickier substances are being processed in the chemical, pharmaceutical and biotechnological industries. Thus, increasingly stringent requirements are also being imposed on the utilised materials and their processing by means of welding technology. In this respect, particular attention is frequently focused on a high corrosion resistance. Often, only special materials such as nickel alloys, duplex steels, titanium, zirconium or tantalum are appropriate in such cases. Using the example of the Kasag Langnau company, the article describes what must be borne in mind when such materials are welded.
