Abstract
Methods for assembly, erection and welding of large-size spherical isothermal tanks of cryogenic application were proposed and implemented. The methods provide a maximum reduction of the scope of assembly-welding operations. A higher efficiency of mechanised welding and labour productivity, as well as shortening of a construction period are achieved.
