In the welding process of automatic spot welding machines, a common problem is that the welding points cannot melt thoroughly and produce splashes, resulting in poor welding quality. Therefore, in practical applications, attention should be paid to:
A welding point is not penetrated, and the molten nucleus is not formed or poorly formed.
No leakage, that is, during spot welding, there is no "bean shaped" arrangement of molten nuclei. This defect is very dangerous as it will greatly alter the welding strength.
Debug welding parameters. If the calibration confirms that the parameters are correct, it is necessary to check the main power circuit, such as whether the power supply is sufficient and whether the welding transformer is damaged.
There are too many automatic spot welding machines.
Check if the insulation resistance between the bracket and the body is poor and if there is a local short circuit.
Check if the contact surface, such as the flexible joints of copper, is severely oxidized, and the formation of contact resistance can exacerbate heating.
Check whether the thickness of the weld seam and the continuity of the load meet the requirements, and whether the welding machine is overheating.
Check whether the inlet pressure, water volume, and supply temperature are appropriate, and whether the system is separated by dirt, which can cause overheating of the electric arm due to poor cooling.
Unexpected spatter generated during welding.
Check if the current is too high or the pressure is too low.
The strength of the welded workpiece is insufficient: the welding current is decreasing, and the welding phenomenon is also not strong.
