In the welding process of the automatic spot welding machine , the common problem is that the welding spot cannot be penetrated and spattered during the welding process, which leads to the poor welding quality of the spot welding machine. Therefore, in actual application, you should pay attention to:

　　1. The welding point is not penetrated, the nugget is not formed or the formation is not good.

　　1. No leakage, that is, no "bean-like" nugget arrangement during spot welding. This defect is very dangerous, it will greatly change the welding strength.

　　2. Debug the welding parameters. If there is no problem with the verification parameters, you need to check the main power circuit, such as: whether the power supply is sufficient, whether the welding transformer is damaged, etc.

　　2. Too many automatic spot welding machines.

　　1. Check whether the insulation resistance between the bracket and the body is bad, and whether it forms a local short circuit.

　　2. Check whether the contact surface, such as the flexible joint of copper, is severely oxidized. The formation of contact resistance will increase heat generation.

　　3. Check whether the thickness of the welding seam and the continuity of the load meet the requirements, and whether the welding machine is overheated.

　　4. Check whether the inlet water pressure, water volume, and water supply temperature are appropriate, and whether the system is separated by dirt, which will cause the electric arm to overheat due to poor cooling.

　　3. Accidental splashing during welding.

　　1. Check whether the current is too large or the pressure is too low.

　　2. Insufficient strength of the welding workpiece: the welding current is getting smaller and smaller, and the welding phenomenon is not strong.
