Abstract

The invention discloses a pipeline welding method and device. The method comprises the steps that physical characteristic parameters of base metal of a to-be-welded pipeline are obtained; wherein thephysical characteristic parameters comprise material types, groove types and groove geometrical parameters; the physical characteristic parameters are input into a preset weld joint shape prediction model to enable the weld joint shape prediction model to output predicted shape parameters of a to-be-generated weld joint according to the physical characteristic parameters; reference welding processparameters are determined according to the predicted shape parameters of the to-be-generated weld joint; and a welding mechanism is controlled to perform welding according to the reference welding process parameters. By implementing the embodiment of the pipeline welding method and device, the problem that the weld joint quality is finally influenced due to unreasonable welding process parametersetting caused by insufficient experience of welding personnel can be solved.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a pipeline welding method and device. Background technique [0002] With the improvement of steel pipe manufacturing level and welding technology, more and more large-diameter pipelines are being constructed. In the process of expanding the scale of pipeline laying, welding, as an important way to connect new and old pipelines, is extremely important for the future use of pipelines. effect. [0003] Before the welding of the existing pipelines, it is necessary for the welding personnel to set the welding process parameters based on their experience, so as to finally obtain a qualified weld. However, for those with insufficient welding experience, the welding process parameters may be unreasonably set, resulting in the unqualified final weld. Contents of the invention [0004] Embodiments of the present invention provide a pipeline welding method and device, which can solve t...
