  • Method for welding pipelines from high-strength pipes with controllable heat input
    Patent number: 10668550
    Abstract: The invention relates to the field of construction, particularly to welding of above- and underground high-strength pipelines with controlled heat input. Application of the invention will increase the load-bearing capacity of the pipelines made with the use of butt-welded pipes, pipe spools, pipe strings. The method includes joining of two or more cylindrical metal pipes, pipe spools and pipe strings by the welded ring butt with the use of the arc welding for the whole perimeter of the pipe. Criteria for a high-quality welded joint include optimal selection of parameters of the welding thermic cycle. The suggested welding method allows to have the optimal structure, high strength and viscoplastic properties in areas of the welded joint, to provide for the required load-bearing capacity of the pipeline and its reliability during operation.
