Interactive welding joint groove graph drawing and parameter tagging method

Abstract

The invention discloses an interactive welding joint groove graph drawing and parameter tagging method. The method comprises the following steps of (1) conducting parametric modeling on a groove graph; (2) establishing an interactive graphic element construction and parameter tagging method; (3) after the groove graph is drawn, storing joint groove parameter information and the groove graph in a database table field through database metadata, and storing the groove graph into a database in a neutral meta file vector format WMF. On the one hand, the size of a graph file is reduced, meanwhile, the vector graph file is loaded into an application program, and parameter tagging and graph property modification can be carried out on the vector graph file to achieve graph data reuse; on the other hand, the neutral groove graph file can be used as an embedded graph object to be output to a process report file, sawteeth or graphic element interruption and other distortion phenomena will not be generated during stepless zooming in a display area, and the graph file has the advantages in the aspects of storage and display compared with a bitmap file.

Description

technical field [0001] The invention relates to an interactive welding joint groove graph drawing and parameter labeling method. Background technique [0002] Welding process informatization is an inevitable link in the development of intelligent welding. The information expression and organization of welding joint process is an extremely important initial step. Its content includes base metal information, welding process electrical parameters and pre-welding, welding process and post-welding In addition to the detection information, it also includes joint graphic information reflecting the joint form and groove geometric parameters, and information representing the weld bead process graphics during the welding process, among which the description, organization and processing of the groove graphic information is the key to the welding process design process. Key points and difficult points. Judging from the current research status at home and abroad, there are mainly two me...

Problems solved by technology

Judging from the current research status at home and abroad, there are mainly two methods for joint graphic expression: the first method is to use bitmaps to describe joint information and groove parameters. This method requires a large number of enumerations due to different combinations of groove types and parameters Joint groove bitmap, the reason is that the groove parameters cannot be marked and modified in time in the bitmap, the efficiency is low, and when embedded into the output process report document, distortion may occur with the change of the bitmap display area; The second method is to use a third-party vector graphics drawing platform. After drawing the joint bevel graphics, use OLE (object linking and embedding, object linking and embedding) technology to import to the process design platform, and then return to vector graphics drawing when modifying platform, this parasitic method is inconvenient when labeling groove parameters and graphics output, and at the same time, the parameter information marked cannot be conveniently used by other software modules, resulting in the isolation of information
