  1. But there are some technical difficults for the welding of aluminium alloy such as some broken bits being easily found, a large welding distortion can happen easily, hard to distinguish the difference between the solid metal and liquid metal colour, hard to control the temperature, a lot of air holes can be seen in the welding line and so on

    但是鋁合金熔化焊時的技術難點在於：焊接時易引起夾渣，焊接變形大，金屬的固態和液態的色澤不容易區別，焊接操作時控制溫度困難，容易產生氣孔等等。如果焊前清理工作不是很好，檢測氣孔往往超標。
  2. According to these, the paper put forward some countermeasures : select low carbon steel or low metal alloy steel with lower intensity, like 20r steel ; while welding, adopt strict craft measures with lower welding heat to input ; after jointing, proceed the whole hot dissolving on time ; control each welding joint with hardness hb 185 ; add 0. 25 % water into the liquid ammonia as decay eclipse ; enhance checking in operation, repairing equipment in time through regular interior and exterior checking

    針對上述原因提出了防止氨冷器類臨氨壓力容器產生應力腐蝕裂紋的對策：選用強度稍低，但抗裂性較好的低碳鋼和低合金鋼，如用20r鋼製造；焊接時應採用嚴格的工藝措施和較低的焊接熱輸入量；焊后應及時進行整體消除應力熱處理；控制焊接接頭各區硬度hb 185 ；在液氨中添加0 . 25 %的水作為緩蝕劑；在運行中加強檢查，及時進行停車檢修時的內外部檢查和定期檢驗。
  3. Several methods on joining of ceramic / metal are reviewed. the joi ning of ceramic / metal brazing, partial transient liquid bonding and shs welding on power engineering and high - temperature composite of advanced jet engine, are emphasized

    綜述了陶瓷與金屬連接的幾種方法，重點討論了對未來動力工程和先進發動機有重要意義的陶瓷與金屬釬焊連接、部分瞬間液相連接及自蔓延高溫合成（ shs ）連接。
