【摘要】 研究镀锌板和合金化镀层板对电阻点焊工艺窗口和电极寿命的差异。结果表明,合金化镀层板点焊电流范围比镀锌板点焊电流范围宽16%,电极寿命大于镀锌板。随着焊接电流的增加,点焊接头剪切力先增加后减小。相同焊接工艺时,合金化镀层板点焊接头剪切力高于镀锌板,接头最大剪切力分别为4.83 kN和4.43 kN。更多还原

【Abstract】 Effect of galvanized plate and galvanneal plate on the process window and electrode life of the automobile plate. The results show that the current scope of galvanneal plate is 16% broader than galvanized plate,and the electrode life of galvanneal plate is bigger than galvanized plate. With the increasing of the welding current,the shear force of joints increases first and then decreases.The shear force of galvanneal plate is higher than galvanized plate with the same welding process,the maximum shear stress of joints is 4.83 kN and 4.43 kN respectively.更多还原
