（一）焊縫不合格。焊縫不合格是因焊接工藝參數(shù)選擇不當(dāng)，或操作技術(shù)不熟練，導(dǎo)致焊縫高低寬窄不一，焊縫成形不良，背面焊縫下凹。造成焊縫減弱過多，使焊縫強(qiáng)度不夠。 </p> <p> （二）未焊透或被燒穿。未焊透是主要有以下原因，一是電流過小，二是操作技術(shù)不熟練，四川304不銹鋼無縫焊管，焊接速度太快，對接間隙小，三是電弧過長或電弧未對準(zhǔn)焊縫等，如果導(dǎo)致焊絲與基體金屬未熔合在一起或焊接金屬中局部未熔合的時候，該部位應(yīng)及時進(jìn)行補(bǔ)焊。燒穿的原因是因焊接電流過大，熔池溫度過高，焊絲加入不及時，四川304不銹鋼無縫焊管，帶鋼對接間隙過大，焊接速度過慢等，導(dǎo)致焊縫上出現(xiàn)單個或連續(xù)的穿孔。使焊縫強(qiáng)度減弱，從而被燒穿。

不銹鋼焊管，顧名思義，就是焊接管，與不銹鋼無縫鋼管一樣，只是鋼管里的一個種類，主要用在工程施工部門；而不銹鋼無縫鋼管則是一種具有中空截面、周邊沒有接縫的長條鋼材，具有壁厚不均勻、管內(nèi)外表光亮度低、定尺成本高等特點(diǎn)，因此主要用于高強(qiáng)度、高壓等結(jié)構(gòu)用材方面。從生產(chǎn)用途方面來看,不銹鋼焊管主要用輸送水、油、空氣，以及取暖熱水或蒸汽等一般較低壓力流體和其他用途，某些焊接管還可用于礦山壓風(fēng)、排水、軸放瓦斯等方面。 </p> <p> 而不銹鋼無縫管既可用在工程及大型設(shè)備上輸送流體管道，也可用于電站及核電站鍋爐上耐抗高溫、高壓的輸送流體集箱及管道等等。 </p> <p> <br /> </p><p> 東南沿海等地區(qū)很多廠房每隔2年就需要更換一次屋頂，代價高昂。為解決這一問題，建筑、鋼鐵行業(yè)不斷探索、實(shí)踐，提出以耐腐蝕、延展性較強(qiáng)的不銹鋼作為屋頂建筑材料。然而不銹鋼材質(zhì)色澤單一，易反射光線，既不美觀又會造成光污染。據(jù)介紹彩鋼板生產(chǎn)工藝在不增加鋼鐵產(chǎn)能的前提下，采用具有自主知識產(chǎn)權(quán)的著色技術(shù)。通過“冷軋－著色”短流程生產(chǎn)工藝，提高彩鋼生產(chǎn)效率，實(shí)現(xiàn)了不銹鋼主體與著色一體化。這種彩鋼板生產(chǎn)工藝尚屬國內(nèi)首創(chuàng)，填補(bǔ)了不銹鋼連續(xù)著色生產(chǎn)領(lǐng)域的世界空白，實(shí)現(xiàn)了不銹鋼材料色澤美觀與安全防腐性能的有效結(jié)合。技術(shù)參數(shù)編輯鋼的編號和表示方法①用國際化學(xué)元素符號和該國的符號來表示化學(xué)成份，用阿拉伯字母來表示成份含量：如：中國、俄國12CrNi3②用固定位數(shù)數(shù)字來表示鋼類系列或數(shù)字；如：美國、日本、300系、400系、200系；③用拉丁字母和順序組成序號，只表示用途。中國的編號規(guī)則①采用元素符號②用途、漢語拼音，平爐鋼：P、沸騰鋼：F、鋼：B、甲類鋼：A、T8：特8、GCr15：滾珠◆合金鋼、彈簧鋼，如：20CrMnTi60SiMn、（用萬分之幾表示C含量）◆不銹鋼、合金工具鋼（用千分之幾表示C含量）其中：①奧氏體型不銹鋼用200和300系列的數(shù)字標(biāo)示。焊絲不符合標(biāo)準(zhǔn)時，過熱和晶粒度過度長大，材料本身雜質(zhì)較多，或材料本身易淬硬時均易產(chǎn)生裂紋。</p><div

空氣中常帶有許多粉塵。它們不斷地落在設(shè)備表面。它們可以用水或堿性溶液去除掉。不過，有附著力的塵垢需要高壓水或蒸氣進(jìn)行清理。浮鐵粉或嵌入的鐵在任何表面上，游離鐵都會生銹并使不銹鋼產(chǎn)生腐蝕。因此。必須。浮粉一般可隨粉塵一起掉。有些粘著力很強(qiáng)，必須按嵌入的鐵處理。除粉塵外，表面鐵的來源很多，其中包括用普通碳鋼鋼絲刷清理和用以前在普碳鋼，低合金鋼或鑄鐵件上使用過的砂子、玻璃珠或其它磨料進(jìn)行噴丸處理，或在不銹鋼部件及設(shè)備附近對前面提到的非不銹鋼制品進(jìn)行修磨。在下料或吊過過程中如果不對不銹鋼采取保護(hù)措施，鋼絲繩、吊具和工作臺面上的鐵很容易嵌入或玷污表面。訂貨要求和制作后檢查可以防止并發(fā)現(xiàn)游離鐵的存在，ASTM標(biāo)準(zhǔn)A380[3]規(guī)定了檢查不銹鋼表面鐵或鋼微粒的鐵銹試驗(yàn)法。當(dāng)要求不能有鐵存在的時候，應(yīng)該使用這種檢驗(yàn)方法。如果結(jié)果令人滿意，應(yīng)用干凈的純水或硝酸對表面進(jìn)行洗滌，直到深藍(lán)色完全消失。正如標(biāo)準(zhǔn)A380[3]指出的如果鐵銹試驗(yàn)溶液不能全部干凈，不推薦在設(shè)備的工藝表面，即用來生產(chǎn)人類消費(fèi)品的直接接觸表面采用這種試驗(yàn)方法。比較簡單的試驗(yàn)方法是在水中暴露12~24小時，檢查是否有銹斑。這種試驗(yàn)靈敏性差，而且耗時。在加工過程中，只要損壞是由板面上的劃痕引起的，就很容易對板表面造成損壞。安徽2205不銹鋼無縫焊管生產(chǎn)供應(yīng)</p><p
