不銹鋼裝飾管的焊接操作中，大家市場面臨三大常見問題，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，無錫市場不銹鋼卷零售，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，對接間隙小，無錫市場不銹鋼卷零售，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(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)，帶鋼對接間隙過大，焊接速度過慢等，無錫市場不銹鋼卷零售，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。

不銹鋼焊管不應(yīng)采用刷漆方法除銹。有鈍化要求的不銹鋼焊管不應(yīng)采用套管塔接式對接接頭。總的來說，鈍化膜污損的原因主要有碰撞、擠壓、割劃、各種液體溶劑油脂對其表面的沾污、含其他金屬的塵埃的沉積或嵌入、熱加工引起的氧化色斑。只要在使用中注意避免這些情況，做好防護(hù)措施，就能夠有效地延長不銹鋼焊管的使用壽命。不銹鋼焊管的耐腐蝕性能的高低在很大程度上是取決于其表面鈍化膜的狀況，鈍化膜發(fā)生破損后，不銹鋼焊管就會(huì)失去保護(hù)而形成銹蝕，因此，維持不銹鋼焊管鈍化膜的良好狀態(tài)尤為重要。

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? 觀看外表面和管內(nèi)壁的顏色是否光亮平滑、厚度是否均勻或有粗糙現(xiàn)象.一般焊管此項(xiàng)基本不用檢查,而無縫鋼管是采用冷拔或熱軋方式生產(chǎn)的,在生產(chǎn)過程中操作不當(dāng)容易產(chǎn)生厚度不均勻、管面有裂紋等現(xiàn)象,而表面粗糙一般是無縫管未進(jìn)行拋光處理,若對外觀無特別要求不影響使用. l、選購時(shí)應(yīng)選擇經(jīng)質(zhì)量技術(shù)監(jiān)督局評定的產(chǎn)品.在客戶中有長時(shí)間使用見證和良好口碑是**直接有效的選購方法. 2、軋制管中經(jīng)常會(huì)出現(xiàn)內(nèi)重皮、麻點(diǎn)、和軋制青線,一般情況下這些無法避免,也基本不影響使用,但在選購時(shí)一定要選擇盡量少的,特別是檢查內(nèi)表面. 現(xiàn)在的304不銹鋼管不僅是種類繁多，有些商家因?yàn)閭€(gè)人利益會(huì)購買一些質(zhì)量特別差的賣出，我們就要特別注意，掌握以上技巧，我們在挑選304不銹鋼管時(shí)就會(huì)挑選出我們稱心如意的好產(chǎn)品了 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p>
