style="text-indent:25px">焊管成型。為了合理控制殘余應(yīng)力，不僅需要采用針對(duì)性的設(shè)備和工藝，還需要在鋼管成型前進(jìn)行必要的成型工藝評(píng)定，對(duì)成型的設(shè)備、材料、產(chǎn)品的規(guī)格、預(yù)彎的程度、成型的速度、成型的壓力、參數(shù)等進(jìn)行試驗(yàn)和評(píng)定，合格后方進(jìn)行焊管成型。焊前預(yù)熱。要根據(jù)具體的材質(zhì)、具體的工作環(huán)境確定預(yù)熱及層間溫度。埋弧焊時(shí)，為了減少焊接熱輸入，不建議采用多絲焊，建議盡量采用單絲多道焊，焊道平行排列，且每條焊道的寬度控制在15min以?xún)?nèi)；層間溫度控制在110-250℃。焊道越寬，產(chǎn)生橫裂的可能性越大。焊接時(shí)，要盡量地采用窄焊道，多分道，減少焊道寬度，減少熱輸入。焊絲。選擇低強(qiáng)度的焊絲，這樣可以適當(dāng)降低焊縫的碳當(dāng)量，提高焊縫的塑性，有助于減少焊接裂紋的產(chǎn)生。同時(shí)注意使用不鍍銅的焊絲，防止銅或銅合金進(jìn)入焊縫熔池。另外需要注意防潮和防生銹。舟山焊接技術(shù)改造電弧的長(zhǎng)度與焊條涂料種類(lèi)和藥皮厚度有關(guān)系。</p><div

style="text-indent:25px">選擇合理的焊接順序盡量使焊縫自由收縮。焊接焊縫較多的結(jié)構(gòu)件時(shí)，應(yīng)先焊錯(cuò)開(kāi)的短焊縫，再焊直通長(zhǎng)焊縫，以防在焊縫交接處產(chǎn)生裂紋。如果焊縫較長(zhǎng)，可采用逐步退焊法和跳焊法，使溫度分布較均勻，從而減少了焊接應(yīng)力和變形合理的裝配和焊接順序。先焊收縮量大的焊縫，后焊收縮量較小的焊縫；焊縫較長(zhǎng)的焊件可以采用分中對(duì)稱(chēng)焊法、跳焊法，分段逐步退焊法。交替焊法；焊件焊接時(shí)要先將所以的焊縫都點(diǎn)固后，再統(tǒng)一焊接。能夠提高焊接焊件的剛度，點(diǎn)固后，將增加焊接結(jié)構(gòu)的剛度的部件先焊，使結(jié)構(gòu)具有抵抗變形的足夠剛度；具有對(duì)稱(chēng)焊縫的焊件好成雙的對(duì)稱(chēng)焊使各焊道引起的變形相互抵消；焊件焊縫不對(duì)稱(chēng)時(shí)要先焊接焊縫少的一側(cè)。</p><p style="text-indent:25px">焊接加熱過(guò)程中要向接頭區(qū)域輸入很多熱量，對(duì)焊縫附近區(qū)域形成加熱和冷卻過(guò)程，這對(duì)靠近焊縫的熱影響區(qū)的組織性能有很大影響，從而引起熱影響區(qū)硬度、強(qiáng)度、韌性、耐蝕性等的變化。與焊縫金屬不同，焊接時(shí)熱影響區(qū)的化學(xué)成分一般不會(huì)發(fā)生明顯的變化，而且不能通過(guò)改變焊接材料來(lái)進(jìn)行調(diào)整，即使有些元素可以由熔池向熔合區(qū)或熱影響區(qū)粗晶區(qū)擴(kuò)散，那也是很有限的。因此，母材本身的化學(xué)成分和物理性能對(duì)熱焊接性具有十分重要的意義。工業(yè)上大量應(yīng)用的金屬或合金，對(duì)焊接熱過(guò)程有反應(yīng)，會(huì)發(fā)生組織和性能的變化。即使是一些不發(fā)生相變的純鋁、純鎳、純鉬等，經(jīng)過(guò)焊接熱過(guò)程的影響，也會(huì)由于晶粒長(zhǎng)大或形變硬化消失而使其性能發(fā)生較大變化。研制新的焊接方法、焊接設(shè)備和焊接材料進(jìn)一步提高焊接質(zhì)量和安全可靠性。</p><div
