class="khcont">焊管“無縫化”的含義焊管和無縫管相比，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，內(nèi)部物理性質(zhì)上也產(chǎn)生了變化。如果能夠在這兩個方面—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，等同于無縫，這就是“無縫化”的含義?！盁o縫化”的兩個方面如上所述，焊管無縫化包含兩個方面的內(nèi)涵，幾何無縫化，使焊縫余高盡可能小;物理無縫化，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。我國和美國標準中內(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)。焊管的物理無縫化幾何無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)的機械性能較低。為此，需要經(jīng)過熱處理細化焊縫區(qū)的晶粒、去除焊接應力，實現(xiàn)與母體金相組織、機械性能的一致化，這個過程我們稱之為焊管的物理無縫化。
