在坡口兩側(cè)停留時間要短，左右擺動運(yùn)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(jìn)口焊絲由于熔渣和鐵液流動性較好，在運(yùn)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(diǎn)操作就行。進(jìn)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?yàn)殍F液不夠造成內(nèi)凹，但又不能送入熔池里。同時焊前進(jìn)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(diǎn)。間隙較大時，焊絲可以隨電弧一起擺動送絲。進(jìn)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(cè)，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。</p></p><br
