焊點質量最常見的問題是焊點強度不夠，其主要影響因素和處理方法如下：
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、檢查點焊機、碰焊機電極壓力是否太小
1, check the spot welder, touch welding electrode pressure is too small
2、檢查焊接能量是否太小接觸不良。檢查電極杆是否緊固好
。焊接工件是否鏽蝕嚴重．
2, check the welding energy is too small to poor contact. Check whether the electrode rod fastening well. Welding workpiece is corroded seriously.
3、檢查電極頭和電極扡、電極杆和電極臂之間是否氧化物過多。
3, check whether between the electrode head and electrode skewer, electrode pole and the electrode arm oxide too much.
4、檢查電極頭截面是否因爲磨損而增大，造成焊接能量減小。
4, check whether the electrode head section increases because of wear and tear, causing welding energy decrease.
5、檢查電極和銅軟線的結合面是否嚴重氧化。根據檢查出來的故障部位進行修理、換件、調整，即可保證焊點的強度。
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.
