Manufacture and transportation technology for double-joint integrally-welded trusses

The invention discloses a manufacture and transportation technology for double-joint integrally-welded trusses. The manufacture and transportation technology comprises a 30 m long rod and integrally-welded truss size dimension control technology, a truss replacing-curve-by-straight-line matching and splicing technology, a large superheavy truss overturning and transporting technology and a truss three-dimensional shipping and delivering technology. The manufacture and transportation technology for the double-joint integrally-welded trusses is characterized in that a replacing-curve-by-straight-line splicing scheme is adopted for match and manufacture of truss matching and splicing, and welding parameters are optimized on a basis of software simulation welding; a welding sequence is detailed; overturning hoops, lifting appliances and a transportation support for the trusses are designed according to the structure characteristics of the trusses; and a shipping fastening scheme is designed.
