In addition to the welding roller frame to protect the high-temperature welding area from air damage, the experiment determined to maintain the gas mixing ratio. Maintenance Gas in addition to blocking air. It also affects and even determines the morphological characteristics of arc, process characteristics and metallurgical characteristics of weld.
According to the steel type of workpiece, plate thickness, weld space orientation, quality requirements of welded joints, welding productivity and reasonable maintenance gas mixing ratio, it can ensure excellent weld formation and prevent spatter. According to the different effects of carbon dioxide and argon in the welding process, we determine a reasonable range, and through experimental verification, when the proportion is high, the quality is excellent.
The active tracking system in the welding roller frame directly affects the positioning of the molten pool; The uncoordinated driving devices of the equipment will lead to instability or suspension of the welding project. During welding. Active welding has strict requirements for weldment groove, pressure vessel environment and data, and the improvement of welding process is based on the requirements of process planning.
We analyze the causes of welding problems, and manage, verify and adjust them one by one. The gas maintenance welding of inner circumferential seam carries out experiments on various process parameters, discusses and determines the habitual values of parameters to make them match each other, especially the control of welding gun orientation. Through the television supervision system and the 012 axis sliding plate in the three-dimensional electric vane, adjust the orientation of the welding gun according to the welding condition at any time, so as to ensure the stability of the welding process.
