因此,加強(qiáng)焊工單面焊雙面成形操作技能的訓(xùn)練是保證毛細(xì)銅管焊縫質(zhì)量的關(guān)鍵，焊接電流應(yīng)根據(jù)毛細(xì)銅管厚度、焊接位置、焊條直徑和焊接經(jīng)驗(yàn)進(jìn)行選擇,保證所選擇的電流不易造成焊縫咬邊、燒穿、夾渣、未焊透等缺點(diǎn). 毛細(xì)銅管焊接過程中應(yīng)選擇短弧焊,以避免咬肉、未焊透、氣孔等缺點(diǎn)的產(chǎn)生. 焊速應(yīng)合適,不宜過慢,以每層厚度不大于4 mm為宜, 以避免高溫停留增長,影響毛細(xì)銅管焊縫的機(jī)械性能,但焊速也不宜過快,以免造成未溶合、未焊透等缺點(diǎn)。</p><div style="width:100%;text-align:

style="text-align:center;"> <span style="color:#003399;font-size:16px;">毛細(xì)管的選擇方法</span> </p> <p> 毛細(xì)管的內(nèi)徑和長度必須經(jīng)選擇，但毛細(xì)管的理論計(jì)算比較復(fù)雜，計(jì)算結(jié)構(gòu)誤差也很大，所以一般均在選定內(nèi)徑之后，再來決定長度，在規(guī)定的條件下根據(jù)試驗(yàn)結(jié)果來決定毛細(xì)管尺寸。 </p> <p> 1.氮?dú)鉁y定法和液體測量法：測量方法是在毛細(xì)管連接在入口壓力為表壓980KPa的容器上，環(huán)境溫度保持不變，測量毛細(xì)管每分鐘的液體流量值。 </p> <p> 2.在制冷系統(tǒng)上直接測定毛細(xì)管流量：在制冷系統(tǒng)排氣管上連接一個(gè)壓力計(jì)。吸氣口與表壓力為零的干燥空氣或氮?dú)庠聪嘟印ｉ_啟壓縮機(jī)后，制冷系統(tǒng)壓力（電冰箱）**1好達(dá)到1200--1300KPa（蒸發(fā)溫度為-15℃至-18℃），如果希望改變蒸發(fā)器壓力，只需要加長或減短毛細(xì)管的長度就可以實(shí)現(xiàn)了。這種方法操作簡單，精度不高，可在維修時(shí)使用。 </p> <p> 3.空調(diào)機(jī)和冷飲機(jī)一類的制冷系統(tǒng)一般使用“空調(diào)工況”，毛細(xì)管較粗，阻力小，用此方法測定毛細(xì)管的空氣流量值，表壓力可達(dá)到540--590KPa。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
