摘　　要：低碳钢点焊U-I图主要有三种类型:椭圆型、双头型、多头型。未发生飞溅时呈现椭圆状,在发生飞溅时呈现双头或多头状,此外基于点焊质量检测研究的点焊U-I图反映焊接过程动特征的特征信息,可为低碳钢焊接参数的优化提供依据。U-I curves of mild steel welding spot have ellipse,double-ended and multi-ended models. When no splash happens,the U-I curves shapes ellipse.If one splash happens in the welding,U-I curves shapes double-ended.If many,multi-ended shapes were found.And then,U-I curves which based on spot welding quality inspection can reflect the dynamic characteristic information of spot welding process,it can provides bases on optimizing parameters in spot welding.

关 键 词：点焊 U-I图 质量检测
