焊接(jie)(jie)鋼管在(zai)(zai)使用(yong)前需要經(jing)過各(ge)種工(gong)(gong)(gong)藝處理，焊接(jie)(jie)鋼管的(de)(de)熱(re)處理是焊接(jie)(jie)鋼管加(jia)工(gong)(gong)(gong)中非常重要的(de)(de)一(yi)個(ge)環節(jie)。熱(re)加(jia)工(gong)(gong)(gong)是一(yi)種金屬(shu)熱(re)加(jia)工(gong)(gong)(gong)過程，在(zai)(zai)這一(yi)過程中，金屬(shu)材料(liao)在(zai)(zai)一(yi)定的(de)(de)介質(zhi)中被(bei)加(jia)熱(re)絕緣和(he)(he)(he)冷卻，通過改變材料(liao)表(biao)面或內部的(de)(de)金相(xiang)組(zu)織來控(kong)制(zhi)金屬(shu)性能。結構焊接(jie)(jie)鋼管工(gong)(gong)(gong)件在(zai)(zai)加(jia)熱(re)和(he)(he)(he)冷卻過程中，由于(yu)表(biao)層和(he)(he)(he)芯層的(de)(de)冷卻速(su)度和(he)(he)(he)時間不一(yi)致，形成(cheng)溫差，導致體積膨脹和(he)(he)(he)收縮不均(jun)勻，產生應力，即熱(re)應力。焊管加(jia)工(gong)(gong)(gong)過程中有很多工(gong)(gong)(gong)序，我們需要注意每(mei)一(yi)個(ge)細節(jie)。你可以(yi)了解焊管加(jia)工(gong)(gong)(gong)中焊接(jie)(jie)鋼管的(de)(de)熱(re)處理。
