(1)離子氣和保護(hù)氣離子氣是等離子弧的工作氣體,對(duì)電弧起壓縮作用,并對(duì)鎢極和熔池起保護(hù)作用。離子氣流量過大,對(duì)電弧壓媚過強(qiáng),增加電弧剛度,使熔深增加,基體沖淡率加大。離子氣過小,電弧無力,等離子弧不穩(wěn),試驗(yàn)時(shí)選擇300400L/h保護(hù)氣是保護(hù)熔池不被氧化的氬氣流,在電弧周圍呈圓錐狀,其致密度直接影響熔池的保護(hù)效果。試驗(yàn)時(shí)選擇750~850L/h離子氣和保護(hù)氣均采用工業(yè)用純(含氬99%)。(2)轉(zhuǎn)移弧電流與電壓排絲等離子弧堆焊的非轉(zhuǎn)移弧只起過渡引燃轉(zhuǎn)移弧作用,轉(zhuǎn)移弧引燃后即被切斷。因此轉(zhuǎn)移弧電流規(guī)范是保證堆焊質(zhì)量的主要工藝參數(shù)。電流過小,堆焊金屬與基體得不到良好的冶金結(jié)合。電流過大,自磁壓縮性增大,熔池溫度過高,熱量增加,因而使基體熔深和沖淡率增加。試驗(yàn)選用電流為180~230A。轉(zhuǎn)移弧電壓受鎢極與工件之間距離影響距離大則電壓高,反之亦然。轉(zhuǎn)移弧電壓過低,電弧軟弱無力,穿透力小,易形成未焊透缺點(diǎn)。一般選為35~40V。</p><p> 在堆焊過程中，焊炬除了按上述方法作階梯式的向前移動(dòng)外，還需沿著堆焊面作橫向擺動(dòng)，這樣可以提高堆焊層的均勻性和平整度。每堆焊一層可得到2～3mm厚的堆焊層，每層連續(xù)一次堆焊好。如果需要得到更厚的堆焊層，則須多層堆焊，層間須用砂輪或鋼絲刷進(jìn)行清理和平整，而后再堆焊下一層。根據(jù)需要可以用火焰重新熔化堆焊層（重熔），以減少堆焊層金屬的缺點(diǎn)，提高堆焊層質(zhì)量。（3）堆焊時(shí)，焊絲的熔化端、熔池必須始終處于“三倍乙炔過剩焰”的保護(hù)之中，使它們與空氣隔絕。不得將焊炬急速地從熔池表面移開。堆焊搭接時(shí)，應(yīng)使接頭重疊15～20mm，收尾時(shí)須將焊炬繼續(xù)前移40～50mm，焊炬逐漸抬起，火焰逐漸離開熔池，使熔池逐漸縮小。這樣，接頭處的冷卻速度緩慢，不至于產(chǎn)生接頭疏松、縮孔、火口裂紋等缺點(diǎn)?；鹧媸湛谠诃h(huán)縫的內(nèi)側(cè)為好，這樣可以減少堆焊接頭的收縮應(yīng)力。等離子粉末堆焊是以等離子弧作為熱源，應(yīng)用等離子弧產(chǎn)生的高溫將合金粉末與基體表面迅速加熱并一起熔化、混合、擴(kuò)散、凝固，等離子束離開后自激冷卻，形成一層高性能的合金層，從而實(shí)現(xiàn)零件表面的強(qiáng)化與硬化的堆焊工藝。有誰知道上海鉆桿堆焊的技術(shù)難點(diǎn)。</p><div
