Abstract

The invention discloses a welding process parameter optimization method suitable for different pipe diameters. The welding process parameter optimization method comprises the following steps that firstly, the diameter D of a to-be-welded pipeline is obtained; secondly, the current crawling angle of a welding robot is collected, and the value of a pipeline welding area is determined according to the current crawling angle; thirdly, the pipeline diameter D and the current crawling angle of the welding robot are correspondingly converted into area values to be input into a technological parameter control formula, and welding current I is obtained; and fourthly, the welding robot is controlled according to the welding current I, and all-position welding of a pipeline is achieved. According to the method, the problem that during welding field operation of pipeline welding engineering in the petrochemical industry, a professional welder needs to observe a welding seam in real time and frequently adjust welding current in the welding process, and consequently the welding quality is difficult to guarantee is effectively solved, and all-position intelligent welding is achieved.

Description

technical field [0001] The invention relates to the technical field of automatic welding. More specifically, the present invention relates to a welding process parameter optimization method adapting to different pipe diameters. Background technique [0002] For a long time, my country's petrochemical industry has had a decisive impact on the country's economic development. The petrochemical industry involves a huge amount of pipeline welding operations, harsh on-site operating environments, and low automation. In recent years, there are fewer and fewer young welders, a shortage of manual welder resources, and increased costs have become common problems faced by many chemical construction units. The petrochemical pipeline welding project puts forward higher requirements for the quality, efficiency and automation level of pipeline welding. However, during on-site welding, the position of the pipeline to be welded is fixed and cannot be rotated. The welding requirement of the...
