摘要：

Effect　of　bonded　area　on　shear　strength　and　failure　mode　of　galvanized　low　carbon　steel/6061　Al　alloy　CMT　brazed　joint　was　studied.　The　results　show　that,　with　the　increasing　welding　torch　offset　the　bonded　area　of　CMT　joint　decreases　and　the　wetting　angle　increases.　That　leds　to　the　decreasing　of　shear　strength,　and　the　joint　failure　position　transferring　from　fused　Al　area　to　steel/aluminum　interface　layer.　Based　on　the　experimental　results,　a　numerical　model　of　lap-shear　process　of　CMT　joint　considering　the　failure　criterion　of　interface　layer　is　established.　The　reason　of　bonded　area　influencing　shear　strength　and　failure　mode　of　CMT　joint　is　discussed.
