Method and device for determining welding posture of pipeline assembly and upper computer

Abstract

The invention provides a method and device for determining a welding posture of a pipeline assembly and an upper computer, and relates to the technical field of pipeline assembling. The method for determining the welding posture of the pipeline assembly comprises the following steps that the spatial position posture of each part in the pipeline assembly in the pipeline assembly is acquired, wherein the parts comprise guide pipes, two-way connecting parts and / or three-way connecting parts; the information of the pipe feeding amount, the rotation angle and the bending angle are acquired when theguide pipes are bent; the scribing positions of the head ends and / or the tail ends of the guide pipes are determined according to the information of the pipe feeding amount, the rotation angle and the bending angle during bending and the spatial position posture of each part; and according to the scribing positions, the welding posture of the pipeline assembly is determined. According to the scheme of the method and device for determining the welding posture of the pipeline assembly and the upper computer, the step of building a combined clamp in the welding process of a complex pipeline assembly is omitted, the manual operation amount is reduced, and the welding efficiency of the complex pipeline assembly is improved.
