class="khcont">焊管“無(wú)縫化”的含義焊管和無(wú)縫管相比，的區(qū)別是焊管有一道焊縫。由于有了焊縫，使外形凸出高于母材很多，明顯地看出了“縫”;同時(shí)，內(nèi)部物理性質(zhì)上也產(chǎn)生了變化。如果能夠在這兩個(gè)方面—外在與內(nèi)在，都能使焊縫與母材相同、相近或者相等母材性能，等同于無(wú)縫，這就是“無(wú)縫化”的含義。“無(wú)縫化”的兩個(gè)方面如上所述，焊管無(wú)縫化包含兩個(gè)方面的內(nèi)涵，幾何無(wú)縫化，使焊縫余高盡可能小;物理無(wú)縫化，使焊縫(包括周圍熱影響區(qū))的物理性能趨于與母材一致。焊管的幾何無(wú)縫化光滑地掉焊縫處因擠壓焊接后所形成的外毛刺和內(nèi)毛刺，使焊管在幾何外形上幾乎看不到焊縫。我國(guó)和美國(guó)標(biāo)準(zhǔn)中內(nèi)毛刺的殘留高度大致上規(guī)定了兩檔精度:檔(O.127mm;第二檔0.254mm)。焊管的物理無(wú)縫化幾何無(wú)縫化處理后的焊管雖然外表上已幾乎看不到焊縫，但焊縫內(nèi)部的金相組織與母材仍有較大區(qū)別，焊縫區(qū)的機(jī)械性能較低。為此，需要經(jīng)過熱處理細(xì)化焊縫區(qū)的晶粒、去除焊接應(yīng)力，實(shí)現(xiàn)與母體金相組織、機(jī)械性能的一致化，這個(gè)過程我們稱之為焊管的物理無(wú)縫化。
