在坡口兩側停留時間要短，左右擺動運弧速度要慢，向前焊接速度要稍快，這樣熔池溫度較低，里口不易咬邊和塌陷，同時避免焊縫金屬過熱。進口焊絲由于熔渣和鐵液流動性較好，在運弧時基本和一般氬弧焊相近，但在左右擺動時不可過快。（5）仰位置焊接方法國產(chǎn)焊絲由于涂層較厚，鐵液流動性差，不易往下淌，在焊接水平固定口的仰焊位置時只要把焊絲送到坡口的背面，背面的焊縫高度就能凸出來，其他焊接手法按照前述4點操作就行。進口焊絲仰焊位置操作方法：電弧在坡口的根部，焊絲在坡口的背面，并且始終在電弧的前端，一定要多送焊絲，送的少就會因為鐵液不夠造成內(nèi)凹，但又不能送入熔池里。同時焊前進的速度要小，如果速度太快，內(nèi)口每個焊紋之間連接不上，就會在焊紋之間形成咬邊和內(nèi)凹缺點。間隙較大時，焊絲可以隨電弧一起擺動送絲。進口焊絲鐵液流動性好，仰焊位置內(nèi)口焊縫高度凸出，比國產(chǎn)焊絲難度較大，成形沒有國產(chǎn)的好。（6）接頭方法收弧比較好收在坡口側，否則容易出現(xiàn)縮孔或者夾渣。比較好把接頭打磨成斜坡，否則容易出現(xiàn)接頭熔合不好或者內(nèi)口臺階狀焊道。焊接接頭時先熔化接頭再添加焊絲焊接，如果焊接接頭時背面熔渣已經(jīng)脫落，此時的接頭速度要較快。河南卡斯特林焊條錳與硫化合形成硫化錳浮于熔渣中，從而減少焊縫熱裂紋傾向。</p><div

堆焊方法的選擇主要考慮稀釋率、熔敷速度、成本及適用性等因素。藥芯焊絲氣體保護焊由于操作靈活且生產(chǎn)效率較高，可用于氣化爐接管內(nèi)徑＞300mm的接管內(nèi)壁堆焊，對此我們進行了大量的焊材選型及焊接熱處理工藝試驗，選取滿足氣化爐特殊技術要求的不銹鋼藥芯焊絲，掌握了不銹鋼藥芯焊絲氣體保護焊堆焊工藝及接頭性能影響機理，為合理堆焊工藝制定及生產(chǎn)指導提供技術支持。（1）通過對KLM立磨機結構和工作原理分析可知，KLM立磨機結構設計合理，細磨效率高，能耗低，是一種節(jié)能高.效的礦物細磨和再磨裝備。表1各廠家309LMo及316L藥芯焊絲典型化學成分（質(zhì)量分數(shù)）（%）注：標準值欄單個值指所允許的比較大值。?2.試驗我們分別對國內(nèi)外三個廠家（廠家代號分別為GT、DS、JQ）的309LMo+316L不銹鋼藥芯焊絲堆焊組合進行了系列的焊接及熱處理工藝試驗，現(xiàn)詳細介紹如下。（1）試板焊接及熱處理E309LMoT1—1及E316LT1—1藥芯焊絲熔敷金屬化學成分主要技術要求及各廠家典型數(shù)據(jù)如表1所示。各廠家藥芯焊絲均采用CO2氣體保護焊進行堆焊（100.%CO2），堆焊前母材試板預熱至100～150℃，堆焊309LMo過渡層（3～4mm）后進行一次300～400℃、3～4h的消氫熱處理，隨后進行。在焊條前端藥皮有45°左右的倒角，這是為了便于引弧。</p><div
