摘要： A method includes the round billet skelping, several runs of each round billet drawing up to a given size, packing the drawn billets into a multilayer bank, corrugating the bank with the bellows formation as a result and its heat treatment. Each round billet is skelped of the age-hardenable nickel alloy containing components of the following group: niobium, aluminum, titanium, tungsten and molybdenum. Each round billet is drawn, heated up to the temperature of 1000-1130° C., held in the shielding medium at the above temperature, and cooled down, after that the above operations of drawing, heating, holding and cooling are repeated until the given size of each round billet is reached. The drawn round billets are packed into the multilayer bank and the bank is corrugated for forming the multilayer bellows. The heat treatment of the bellows is made by its heating up to the temperature of 1000-1130° C., holding in the shielding medium at this temperature until the strengthening phase is completely dissolved in the alloy and subsequent cooling down to the temperature of the phase transition termination in the alloy. A rarefied air medium or argon are used as the shielding medium.

摘要： The method for prodicing a multilayer thin-walled bellows of stainless steel consists of manufacturing round billets by welding the sheets, packing the round billets into a multilayer bank, corrugating the bank for forming the multilayer bellows and the bellows tightness testing. The round billets are manufactured of the preliminary cut sheets of given dimensions by their electric arc pulsed gas-shielded welding. The packed multilayer bank is welded from two sides over the end faces and subjected to heat treatment by its heating up to the temperature of 1000-1130° C. in the shielding medium and holding at this temperature during 20-45 minutes with subsequent cooling.
