Automatic spot welding machine welding should pay attention to what?

In the welding process of automatic spot welding machine , the common problem is: the welding spot cannot be penetrated during the welding process and spatter is generated, resulting in poor welding quality of the spot welding machine. Therefore, in practical application It should be noted that the welding point of

1. is not penetrated, and the nugget is not formed or formed poorly.

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

2. Debug the welding parameters. If the verification confirms that there is no problem with the parameters, it is necessary to check the main power supply circuit, such as whether the power supply is sufficient and whether the welding transformer is damaged.

2. automatic spot welder too many.

1. Check whether the insulation resistance between the bracket and the body is poor and whether a local short circuit is formed.

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

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

4. Check whether the water inlet 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.

Accidental spatter during 3. welding.

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

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