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(jù)工件鋼種、板厚、焊縫空間方位、焊接接頭質(zhì)量要求、焊接生產(chǎn)率以及合理的維護(hù)氣體混合比，能夠確保焊縫成形杰出，防止飛濺發(fā)生等。咱們依據(jù)二氧化碳和氬氣在焊接進(jìn)程中的不同效果，斷定一個(gè)合理范圍，并通過實(shí)驗(yàn)驗(yàn)證，當(dāng)比例為時(shí)質(zhì)量?jī)?yōu)。

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(dòng)盯梢體系直接影響熔池定位;而設(shè)備各傳動(dòng)裝置的不協(xié)調(diào)將導(dǎo)致焊接工程不安穩(wěn)或中止。焊接進(jìn)程中。主動(dòng)焊對(duì)焊件坡口、壓力容器環(huán)境和資料的要求比較嚴(yán)厲，焊接工藝改善依據(jù)工藝規(guī)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(duì)出現(xiàn)的焊接問題進(jìn)行原因剖析，并逐項(xiàng)進(jìn)行治理、驗(yàn)證和調(diào)整。內(nèi)環(huán)縫氣體維護(hù)焊對(duì)各項(xiàng)工藝參數(shù)進(jìn)行實(shí)驗(yàn)，研討并斷定參數(shù)習(xí)慣值，使其相互匹配，尤其是焊槍方位的控制。通過電視監(jiān)督體系和三維電動(dòng)十字板中的012軸滑板，隨時(shí)依據(jù)焊接狀況，調(diào)整焊槍方位，才干確保焊接進(jìn)程的平穩(wěn)。

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.
