Abstract
An original design of transition piece for joining cryomodules of linear collider was proposed, providing necessary strength, helium and vacuum tightness at relatively low cost. The modes of explosion welding of plane titanium–stainless steel–titanium workpieces, at which intermetallics in the joining zone are almost absent, were developed. The modes of electron beam fillet welding of niobium branch pipe with titanium of a transition disc were selected experimentally. The experimental samples of transition pieces were manufactured which successfully passed tests on thermocycling and helium tightness. 8 Ref., 11 Figures.
Keywords: collider, explosion welding, helium tightness, transition piece, nuclear research
