【正文】 接性、產(chǎn)品結(jié)構(gòu)特點(diǎn)及使用要求，分別確定了MAG焊及埋弧自動焊的焊接接頭的形式、坡口角度以及焊接電流、焊接電壓、焊接速度等焊接工藝參數(shù)。漢德公司引進(jìn)的德國STR系列及MAN系列橋殼的生產(chǎn)技術(shù)，使得中國的車橋生產(chǎn)質(zhì)量及功能有了巨大的變化，刷新了中國車橋生產(chǎn)的里程碑為我國的汽車行業(yè)發(fā)展做出了具大貢獻(xiàn)。通過新技術(shù)的引進(jìn)使得中國的車橋生產(chǎn)在國際上有一定的影響力，值得我們作為漢德人感到驕傲關(guān)鍵詞：汽車后橋殼，焊接，埋弧自動焊，MAG焊ABSTRACTThe real axle shield is a key part of chassis in automobile, inside which installs the spindle reducer, semiaxis and other parts. The shield can bear the gravity of automobile and transmit various forces from wheels to the auto frame or body via the suspension system. Welding is the main process means for manufacturing the vehicle axles. Based on the research for welding vehicle axle shield, after having been introduced the profile of welding, new technology as well as the tendency of its development, this paper is focused on the analysis of highquality lowcarbon steel 16 Mn, the structure of welding, selection for welding methods as well as materials. the proper welding processing of axle shield and the autowielding schemes have been designed.After thorough analysis, the MAG welding processing which can be obtained better prehensive mechanical properties and lower costs for girth wielding has been selected for jointing the axle shield and the semiaxis sleeve girth. The unionmelt welding is also adopted as a processing for jointing the shield. Under the acquaintance of the highquality lowcarbon steel 16 Mn and its requirement for welding characteristics, series of parameters for MAG and unionmelt welding have been confirmed
