摘　　要：在生产实践的基础上,研究了触桥焊接区不同形状对Ag C触头材料电阻焊接过程及结果的影响。对比了条纹状与点状的焊接区形状对焊接工艺参数的要求,以及对产品硬度、焊接面积、焊接强度、外观质量的影响。结果表明:点状焊接区形状的产品所需要的焊接电流更低;两种形状对触头硬度的影响无明显区别,但点状产品焊接对触桥硬度的影响要比条纹状产品大;两种形状对焊接面积及焊接强度的影响不明显;点状产品溢出料可以做到更小,但需要更精确的控制工艺参数。Different shapes with stripes and dots on the welding area of carriers have different influences on the resistance welding process and products for AgC contact assemblies. The influences on the welding parameters, hardness, welding area, welding strength and appearance quality are analyzed and compared, base on production practices. The results show that dot shape needs lower welding current, and has higher influence on carrier hardness and less Ag overflow, but requires more accurate control parameters than stripe. Both the stripe shape and dot shape have similar influences on contact hardness, welding combination area and bonding strength.
