鎢極氬弧焊焊接不銹鋼薄壁管工程實例
國內(nei)外不(bu)銹(xiu)鋼波(bo)紋管(guan)(guan)(guan)的管(guan)(guan)(guan)坯(pi)均是(shi)(shi)(shi)有(you)(you)縫(feng)(feng)或無縫(feng)(feng)不(bu)銹(xiu)鋼薄(bo)(bo)壁(bi)(bi)(bi)管(guan)(guan)(guan)，其中大部分是(shi)(shi)(shi)焊接而(er)成(cheng)(cheng)的有(you)(you)縫(feng)(feng)薄(bo)(bo)壁(bi)(bi)(bi)管(guan)(guan)(guan)。有(you)(you)縫(feng)(feng)薄(bo)(bo)壁(bi)(bi)(bi)不(bu)銹(xiu)鋼管(guan)(guan)(guan)加(jia)工過程是(shi)(shi)(shi)：鋼帶下料(liao)→卷圓(yuan)→縱(zong)縫(feng)(feng)對(dui)接焊→整形成(cheng)(cheng)有(you)(you)縫(feng)(feng)管(guan)(guan)(guan)坯(pi)，最后擠壓成(cheng)(cheng)形為(wei)波(bo)紋部分。波(bo)紋管(guan)(guan)(guan)壁(bi)(bi)(bi)厚為(wei)0.2～0.6mm材(cai)料(liao)為(wei)18-8型不(bu)銹(xiu)鋼，對(dui)管(guan)(guan)(guan)坯(pi)的縱(zong)焊縫(feng)(feng)要求(qiu)很高，首(shou)先要...
