焊点质量最常见的问题是焊点强度不够，其主要影响因素和处理方法如下：
The most common solder joint quality problem is the joint strength is not enough, the main influence factors and treatment methods are as follows:
1、检查点焊机、碰焊机电极压力是否太小
1, check the spot welder, touch welding electrode pressure is too small
2、检查焊接能量是否太小接触不良。检查电极杆是否紧固好。焊接工件是否锈蚀严重．
2, check the welding energy is too small to poor contact. Check whether the electrode rod fastening well. Welding workpiece is corroded seriously.
3、检查电极头和电极扦、电极杆和电极臂之间是否氧化物过多。
3, check whether between the electrode head and electrode skewer, electrode pole and the electrode arm oxide too much.
4、检查电极头截面是否因为磨损而增大，造成焊接能量减小。
4, check whether the electrode head section increases because of wear and tear, causing welding energy decrease.
5、检查电极和铜软线的结合面是否严重氧化。根据检查出来的故障部位进行修理、换件、调整，即可保证焊点的强度。
Combining the 5, check the electrode and the copper wire surface is serious oxidation. Repair, change parts, adjust according to the fault position check out, to ensure the strength of the solder joint.
