摘　　要：研究了汽车上变速操纵杆焊接冷裂纹产生的原因。认为冷却速度过快是产生冷裂纹的主要原因。通过改进焊接工艺来降低冷却速度和采用低氢型焊条等措施来控制焊接冷裂纹的产生。The reason of welding cold cracking was researched on gear shift controlling lever of car. Fast cooling speed was the main reason of generating cold crackle. Measures were taken to prevent welding cold cracking such as improve welding technology by decreasing cooling speed and adopting low-hydrogen electrode, etc.
