Precautions During Operation of Spot Welding Machine

1. During the batch processing, in order to prevent the spot welding parameters from being unstable and the spot welding nozzle wear from affecting the strength of the parts, the quality and strength of the spot welding should be checked regularly. In order to ensure the strength of the spot welding and the flatness of the solder joints, the upper and lower spot welding nozzle planes should be trimmed with a file in time to make the upper nozzle end approximately arc-shaped (the upper welding nozzle end is not allowed to be severely piled up) , The lower mouth is flat without pits.

2. During the spot welding process, try to avoid sparking when the side of the spot welding nozzle contacts the parts, which will affect the strength of the spot welding and the appearance quality of the parts.

3. When the length of the spot welding part is long, the spot welding should be carried out from the middle to the two ends.

Precautions :

1. If there are no parts with the correct plate thickness shown in the table during production, you can select the power-on time I and the welding current parameter range according to the table according to the total thickness parameter, and finally determine the specific spot welding parameters according to the spot welding results of the test piece.

2. If the diameter and distance of the spot welding spot welding are required on the drawing, they should be processed according to the drawing requirements. If there is no requirement on the drawing, the diameter of the spot welding spot should be Φ6 and the welding spot spacing should be less than or equal to 150.

3. The choice of welding current for 1.5+1.5 plate thickness,

a: When welding a single-layer car and car wall, the welding current should be selected as far as possible to the left section;

b: Try to choose the right interval when welding the head.
