style="text-indent:25px">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。</p><div

首先，恢復(fù)工件尺寸堆焊，由于磨損或加工失誤造成工件尺寸不足，是廠礦企業(yè)經(jīng)常遇到的問題。用堆焊方法修復(fù)上述工件是一種很常用的工藝方法，修復(fù)后的工件不僅能正常使用，很多情況下還能超過原工件的使用壽命，因?yàn)閷⑿鹿に囆虏牧嫌糜诙押感迯?fù)，可以大幅度提高原有零部件的性能。其次，耐磨損、耐熱、耐腐蝕堆焊。磨損和腐蝕是造成金屬材料失效的主要因素，為了提高金屬工件表面耐磨性和耐蝕性，以滿足高溫等的工作條件要求，延長(zhǎng)工件使用壽命，可以在工件表面堆焊一層或幾層耐磨或耐蝕耐熱層。就是將工件的基體與表面堆焊層選用具有不同性能的材料，制造出雙金屬工件。由于只是工件表面層具有合乎要求的耐磨、耐蝕等方面的特殊性能，所以充分發(fā)揮了材料的作用與工作潛力，而且節(jié)約了大量的貴重金屬。</p></p><br
