Description
Technical Field
The invention relates to the technical field of engineering machinery, in particular to a pipeline processing device and a pipeline cutting and welding method.
Background
The drill rod of the rotary drilling rig is formed by splicing steel pipes of different models, the lengths of the steel pipes are different even if the drill rod is of the same model, and the size of the steel pipes generally cannot directly meet the length required by splicing, so that the drill rod needs to cut the steel pipes of different models and lengths into the required length in the manufacturing process and then be spliced for use.
