從單焊道全位置區段、送絲行為、焊接弧長（電壓） 、電流行為分析、工藝試驗和接頭檢驗等幾方面介紹管道全位置打底焊工藝特點，其研究成果對全位置焊接機的製造和調試具有普遍指導意義。Abstract : backing weld procedure technique of all - position narrow gap and thick - walled pipe welding is developed about all - position single - pass welding section analysis, wire feeding behavior, weld arc length, welding current analysis, procedure and joint test. the achievement has general guide meaning to producing and testing all - position welder
文摘:從單焊道全位置區段、送絲行為、焊接弧長（電壓） 、電流行為分析、工藝試驗和接頭檢驗等幾方面介紹管道全位置打底焊工藝特點，其研究成果對全位置焊接機的製造和調試具有普遍指導意義。When flux appears liquid and transparent on both tube and valve, start sweeping flame back and forth along axis of joint to maintain heat on parts to be joined, especially toward base of valve socket
當焊劑變成液態並且在管道和閥門上呈現半透明狀態時，開始將火焰沿著連接部件的軸線進行進退烘烤，以保持連接部件、特別是閥門套筒底座部位的熱度。Backing weld before making main wel back weld
打底焊道When flux appears liquid and transparent on both tube and valve, start sweeping flame back and forth along axis of joint to maintain heat on parts to be joined, especially toward the base of the valve socket
當管道和閥門上的焊劑都變成液狀和透明時，則開始沿著連接軸向前後來會掃著火焰，保持連接部件的溫度，特別是閥門承插口底部的溫度。Aiming at the great challenge of deepwater oil resource exploitation in 21st century china, this paper firstly explained contents of offshore engineering joining technology, then introduced a series of important technologies such as deepwater pipeline laying welding, local dry welding, underwater hyperbaric welding, and friction stir welding, lastly put forward countermeasures to develop offshore engineering joining technology in china
摘要在解釋海洋工程連接技術內涵的基礎之上，針對21世紀我國海洋石油開發深水資源的巨大挑戰，對深水海底管道鋪設焊接、局部乾式焊接、水下乾式高壓焊接以後摩擦疊焊等重要技術進行了介紹，最後提出了發展我國海洋工程連接技術的對策。Abstract : after anticorrosion metal - power spray welding was carried out for prevention of corrosion, the matched anticorrosion electrode is used to make backing weld. the new process can replace the traditional process wi th internal repaired mouth
文摘:管道焊前對管端進行耐蝕金屬粉末噴焊防腐，然後採用與之匹配的耐蝕焊條打底焊，從而取代焊后焊接區內補口防腐的傳統施工工藝，達到了管道焊后可不再進行內補口防腐。Apply flame to valve at base of socket. heat uniformly, sweeping flame from fitting to tube until flux on fitting becomes quite. avoid excessive heating of valve
在閥門的承插口底部進行加熱。要均勻加熱，從連接部到管道掃著火焰，直到連接件上的焊劑不會再發出吱吱聲。要避免過度加熱閥門。4 double - welded groove joints shall have their root passes back gouged to sound metal on the reverse side before proceeding with welding on that side
雙面焊接的坡口焊道，應在焊接前將該面底部焊道逆向刨削，直到其對面露出完好的金屬。分享友人
