　　q345b熱鍍鋅方管的渦流探傷

　　渦流探傷是高(gao)頻焊機鋼管生產(chan)中很(hen)重要(yao)的(de)的(de)加(jia)工工藝(yi)之一，高(gao)頻焊機無(wu)縫(feng)鋼管在流體(ti)力學運輸、建筑材料和集裝箱制(zhi)造等行(xing)業有(you)普遍的(de)主要(yao)用途。依據焊接鋼管的(de)技術標(biao)準，焊接不(bu)可有(you)縫(feng)隙(xi)、裂痕(hen)、未焊接等缺點，表層不(bu)允(yun)許(xu)有(you)超標(biao)準的(de)刮痕(hen)、擠傷等缺點。

　　因為焊(han)接鋼(gang)(gang)管在生產流(liu)水線具備接連、迅(xun)速生產制造(zao)的(de)(de)特性(xing)，焊(han)速15～60米/分(fen)，因而，焊(han)接鋼(gang)(gang)管品質只(zhi)靠人(ren)工(gong)(gong)服(fu)務(wu)過后(hou)檢(jian)測(ce)是沒辦(ban)法(fa)確保的(de)(de);而渦流(liu)探(tan)(tan)傷(shang)檢(jian)測(ce)方式(shi)則具備檢(jian)驗(yan)速度(du)更快(kuai)、無必須與(yu)鋼(gang)(gang)件(jian)表(biao)層藕合、檢(jian)驗(yan)敏(min)感度(du)高、檢(jian)驗(yan)與(yu)生產制造(zao)可順利進行等優勢，依據GB7735《無縫(feng)(feng)鋼(gang)(gang)管渦流(liu)探(tan)(tan)傷(shang)檢(jian)測(ce)方式(shi)｝規范的(de)(de)要求，無縫(feng)(feng)鋼(gang)(gang)管的(de)(de)渦流(liu)探(tan)(tan)傷(shang)檢(jian)測(ce)能夠替代無縫(feng)(feng)鋼(gang)(gang)管的(de)(de)打壓試(shi)驗(yan)，大大減少鋼(gang)(gang)管生產全過程中逐根打壓試(shi)驗(yan)產生的(de)(de)繁(fan)瑣的(de)(de)檢(jian)測(ce)，因而很合適于(yu)焊(han)接鋼(gang)(gang)管加(jia)工(gong)(gong)過程的(de)(de)質量檢(jian)驗(yan)與(yu)質量管理。

　　q345b熱鍍鋅方管的渦流探傷

　　高(gao)頻(pin)焊(han)機(ji)無縫鋼管的(de)(de)渦(wo)流(liu)(liu)檢(jian)測是(shi)把(ba)電(dian)(dian)(dian)(dian)(dian)導(dao)(dao)體(ti)貼近通有交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)線圈，由(you)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)線圈創建交(jiao)替變化電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)場(chang)(chang)，該交(jiao)替變化電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)場(chang)(chang)根(gen)據電(dian)(dian)(dian)(dian)(dian)導(dao)(dao)體(ti)，并與之產生(sheng)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)磁(ci)(ci)(ci)(ci)效應功(gong)效，在電(dian)(dian)(dian)(dian)(dian)導(dao)(dao)體(ti)內創建渦(wo)旋。電(dian)(dian)(dian)(dian)(dian)導(dao)(dao)體(ti)中的(de)(de)渦(wo)旋也會造成自身的(de)(de)電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)場(chang)(chang)，渦(wo)旋電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)場(chang)(chang)的(de)(de)功(gong)效更改(gai)了原電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)場(chang)(chang)的(de)(de)高(gao)低，從而造成 電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)線圈工作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)(he)特(te)性阻抗的(de)(de)更改(gai)。當電(dian)(dian)(dian)(dian)(dian)導(dao)(dao)體(ti)表層(ceng)或近表層(ceng)出現(xian)缺(que)點(dian)時，將危害(hai)到(dao)渦(wo)旋的(de)(de)抗壓(ya)強度和(he)(he)遍布，渦(wo)旋的(de)(de)轉(zhuan)變又(you)造成了檢(jian)驗電(dian)(dian)(dian)(dian)(dian)磁(ci)(ci)(ci)(ci)線圈工作(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)和(he)(he)特(te)性阻抗的(de)(de)轉(zhuan)變，依(yi)據這(zhe)一轉(zhuan)變，就(jiu)可(ke)以間接(jie)的(de)(de)了解電(dian)(dian)(dian)(dian)(dian)導(dao)(dao)體(ti)內缺(que)點(dian)的(de)(de)存有。
