不銹鋼焊管的焊接操作中，大家市場(chǎng)面臨三大常見問題，縫不合格、未焊透或被燒穿、裂紋和氣孔，下面大家跟隨春日不銹鋼來了解這些問題的原因和解決方法吧，掌握正確的焊接技術(shù)，從而科學(xué)安全的完成焊接任務(wù)。（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。（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，焊接速度太快，對(duì)接間隙小，三是電弧過長或電弧未對(duì)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(shí)候，該部位應(yīng)及時(shí)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(shí)，帶鋼對(duì)接間隙過大，焊接速度過慢等，導(dǎo)致焊縫上出現(xiàn)單個(gè)或連續(xù)的穿孔。使焊縫強(qiáng)度減弱，從而被燒穿。

我們應(yīng)該用什么標(biāo)準(zhǔn)去評(píng)判304不銹鋼管的質(zhì)量？不銹鋼管是我們生活中常常會(huì)出現(xiàn)的東西，我們平常就可以自己去購買，但是不是專業(yè)的人看不出他質(zhì)量的好壞，加上現(xiàn)在304不銹鋼管的種類非常多經(jīng)常挑著挑著就挑花了眼，有什么方法能判斷出304不銹鋼管的好壞呢? 一、在挑選304不銹鋼管之前需考慮到不銹鋼管的用途以及使用環(huán)境.如：裝潢用一般使用焊管,流體輸送一般用無縫管,醫(yī)療或廚房要使用衛(wèi)生級(jí)不銹鋼管,承壓使用厚壁管;一般室內(nèi)采用200系列材質(zhì)即可,室外需使用304等材質(zhì),而在酸堿性地方或沿海地區(qū)一般要使用3l6以上材質(zhì). 二、在挑選鋼管時(shí)必須確定材質(zhì)達(dá)標(biāo).以304材質(zhì)為例： l.從價(jià)格上分析,若304不銹鋼管甚至低于市場(chǎng)上30l材質(zhì)的普遍價(jià)格,要仔細(xì)辨別,很可能是其他材質(zhì)冒充; 2.認(rèn)明304不銹鋼管面上是否打鋼印材質(zhì)“304”字樣,并要索取廠家質(zhì)量證明書作為憑證; 3.可用酸性試劑測(cè)試,30秒后材質(zhì)304不變色,20l變黑色; 4.大批量購買可抽取樣品送至**檢測(cè)中心進(jìn)行成分化驗(yàn)檢測(cè). </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 京滬高速鐵路貫串北京、天津、河北、山東、安徽、江蘇、上海7省市，連接環(huán)渤海和長江三角洲兩大經(jīng)濟(jì)區(qū)。四省三市國土面積占全國的6.5%，人口占全國的四分之一，continuance占全國的40%，是我國經(jīng)濟(jì)發(fā)展**活躍和相當(dāng)有潛力的地區(qū)，客貨運(yùn)輸需求旺盛。在這一通道修建一條高標(biāo)準(zhǔn)、大能力的現(xiàn)代化高速鐵路，意義重大。除了對(duì)直接相關(guān)的產(chǎn)業(yè)鏈具有拉動(dòng)作用外，京滬高速鐵路建設(shè)還給環(huán)渤海和長三角地區(qū)經(jīng)濟(jì)發(fā)展帶來強(qiáng)烈的衍生效應(yīng)。負(fù)責(zé)南京大勝關(guān)長江大橋北引橋施工的中鐵十一局團(tuán)體項(xiàng)目經(jīng)理譚發(fā)剛算了一筆賬：他們管段施工線路長度約l9公里，合同投資為9.66億，在京滬高速鐵路建設(shè)標(biāo)段中，盡管中鐵十一局團(tuán)體投資額是**小的，就地取材的砂石、碎石用度就達(dá)到8000多萬元；消耗拉絲不銹鋼板，比的用鋼量還要多，累計(jì)支出近2.3億元；消耗水泥l(xiāng)5萬多噸，累計(jì)支出近5000萬元；繳納給當(dāng)?shù)?*的營業(yè)稅達(dá)2500萬元。直接吸納近3000多名農(nóng)民工參與施工建設(shè)。除此以外，還帶來了大量農(nóng)副產(chǎn)品、服務(wù)業(yè)等方面的需求。

不銹鋼焊管有一定了解的朋友們都知道，不銹鋼焊管有一個(gè)流程叫預(yù)熱處理，這前列程的意義何在呢？對(duì)不銹鋼焊管的品質(zhì)有什么影響呢？看看生產(chǎn)廠家春日不銹鋼是如何解析這前列程步驟的。不銹鋼焊管預(yù)熱處理的目的就是消除鑄錠和鍛造時(shí)所引起的組織不均勻性，改善碳化物的形態(tài)及其分布特征，為**終熱處理做好必要的原始組織準(zhǔn)備。在冷乳輥中，如果碳化物顆粒尺寸過大、形態(tài)不良或者偏析嚴(yán)重，**終熱處理后將造成基體組織和硬度的不均勻，導(dǎo)致軋輥工作層發(fā)生剝落的幾率增加和降低冷軋輥的熱沖擊抗力。為進(jìn)一步改善組織均勻性，改善碳化物的形態(tài)及其分布特征，為軋輥**終熱處理做好必要的原始組織準(zhǔn)備，棍坯鍛造后采取了預(yù)備熱處理，工藝主要采用球化退火十調(diào)質(zhì)工藝。通過不銹鋼焊管預(yù)處理，使輥坯組織的均勻性得到了較大改善。總體來說，這一預(yù)熱步驟關(guān)系到不銹鋼焊管的**終品質(zhì)，是生產(chǎn)廠家都十分重視的生產(chǎn)環(huán)節(jié).
