在大量试验基础上对十字丝的凸焊强度和对母丝本体强度的影响因素进行了研究,指出下陷量是表征凸焊强度的一个重要指标.随着焊接电流、电极压力和焊接时间的增大.下陷量依一定的规律增加而致凸焊强度增加.但母丝本体强度降低.对于具体的焊接工艺条件应有一个最佳的下陷量. On the basis of a large number of experiments, the stud welding strength of cross-hair wire and the factors affecting the strength of the bast wire body are studied, and it is pointed out that the amount of sag is an important index to characterize the welding strength.With the increase of welding current, electrode pressure and welding time Larger amount of sag increases in accordance with a certain law to increase the convex welding strength, but the mother wire body strength decreases for the specific welding conditions should have an optimum amount of sag.
