</p> <p> <br /> </p><p> 不銹鋼焊管的三種焊接技術(shù)介紹。目前，工業(yè)上應(yīng)用的不銹鋼焊管的焊接方法主要有氬弧焊、高頻焊、等離子焊和激光焊等。幾種焊接方法各具特點(diǎn)，目前使用**多的是氬弧焊和高頻焊。下面，就幾類焊接工藝技術(shù)江蘇進(jìn)百洪為大家做個(gè)詳細(xì)地介紹。不銹鋼焊管工藝技術(shù)——?dú)寤『?</p> <p> 不銹鋼焊管要求熔深焊透，不含氧化物夾雜，熱影響區(qū)盡可能小，鎢極惰性氣體保護(hù)的氬弧焊具有較好的適應(yīng)性，焊接質(zhì)量高、焊透性能好，其產(chǎn)品在化工、核工業(yè)和食品等工業(yè)中得到廣泛應(yīng)用。 </p> <p> 焊接速度不高是氬弧焊的不足之處，為提高焊接速度，一般采用三電極焊炬的氬弧焊，焊接鋼管壁厚S≥2mm，焊接速度比單焊炬提高3-4倍，焊接質(zhì)量也得以改善。氬弧焊與等離子焊組合可以焊接更大壁厚的鋼管，此外，在氬氣中5-10%的氫氣，再采用高頻脈沖焊接電源，也可提高焊接速度。 </p> <p> <br /> </p> <p> <br /> 不銹鋼焊管由于退火部分的內(nèi)部晶體結(jié)構(gòu)更均勻和致密，因此它可以產(chǎn)生更高間距的回波。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="海淀區(qū)不銹鋼無縫焊管公司,不銹鋼無縫焊管"

大多出于成本方面考慮），部分客戶甚至要求-15%。①DDQ（deepdrawingquality）材：是指用于深拉（沖）用途的材料，也就是大家所說的的軟料，這種材料的主要特點(diǎn)是延伸率較高（≧53%），硬度較低（≦170%），內(nèi)部晶粒等級在，深沖性能較好。許多生產(chǎn)保溫瓶、鍋類的企業(yè)，其產(chǎn)品的加工比（BLANKINGSIZE/制品直徑）一般都比較高，它們的加工比分別達(dá)、、、。SUS304DDQ用材主要就是用于這些要求較高加工比的產(chǎn)品，當(dāng)然加工比超過。如果原料延伸方面達(dá)不到的話，在加工深拉制品時(shí)產(chǎn)品極易產(chǎn)生裂紋、拉穿的現(xiàn)象，影響成品合格率，當(dāng)然也就加大了廠家的成本；②一般材：主要用于除了DDQ用途外的材料，這種材料的特點(diǎn)是延伸率相對較低（≧45%），而硬度相對較高（≦180HB），內(nèi)部晶粒度等級在，與DDQ用材比較，它的深沖性能相對稍差，它主要用于不需伸拉就能得到的制品，象一類餐具的勺、匙、叉、電器用具、鋼管用途等。但它與DDQ材相比有一個(gè)優(yōu)點(diǎn)，就是BQ性相對較好，這主要是由于它的硬度稍高的緣故。不銹鋼薄板是一種價(jià)格不高的材料，但是客戶對它的表面質(zhì)量要求非常高。不銹薄板在生產(chǎn)過程中不可避免會出現(xiàn)各種缺陷，如劃傷、麻點(diǎn)、沙孔、暗線、折痕、污染等，從而其表面質(zhì)量。不銹鋼焊管生產(chǎn)需有**的生產(chǎn)車間或**固定生產(chǎn)場地，不銹鋼原材料要保證單獨(dú)存放，不能與其它材質(zhì)混放。海淀區(qū)不銹鋼無縫焊管公司</p><p
