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.

依據工件鋼種、板厚、焊縫空間方位、焊接接頭質量要求、焊接生產率以及合理的維護氣體混合比，能夠確保焊縫成形杰出，防止飛濺發生等。咱們依據二氧化碳和氬氣在焊接進程中的不同效果，斷定一個合理范圍，并通過實驗驗證，當比例為時質量優。

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.

焊接滾輪架中的主動盯梢體系直接影響熔池定位;而設備各傳動裝置的不協調將導致焊接工程不安穩或中止。焊接進程中。主動焊對焊件坡口、壓力容器環境和資料的要求比較嚴厲，焊接工藝改善依據工藝規劃要求。

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.

咱們針對出現的焊接問題進行原因剖析，并逐項進行治理、驗證和調整。內環縫氣體維護焊對各項工藝參數進行實驗，研討并斷定參數習慣值，使其相互匹配，尤其是焊槍方位的控制。通過電視監督體系和三維電動十字板中的012軸滑板，隨時依據焊接狀況，調整焊槍方位，才干確保焊接進程的平穩。

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.
