Automobile shock absorber Automobile shock absorber is a key component of the automobile, and its quality has a direct impact on the performance of the automobile. The function of the shock absorber is to reduce the vibration caused by poor road conditions, and at the same time reduce the shaking of the vehicle body when the vehicle makes a sharp turn or brakes suddenly.

Question image Problem and reason Countermeasures against Panasonic welding machines

对策前（专机）的焊接效果

question:

1. Large splash at arc start

2. Undercut on the upper edge of the weld

3. Large shrinkage cavity at the end of welding

4. Low efficiency of special machine welding machine

reason:

1. The longer dry elongation at the arc start leads to large splash (determined by the joint form)

2. Due to the sinking of the molten pool due to horizontal welding, the upper edge is prone to undercut

3. For special machine welding, the process of adding arc closing current through PLC at the end of welding is very complicated

4. Only single-station and single-piece welding can be performed, and the welding cycle is 8-10s/piece

Robots instead of private planes

1. Teach the starting position of welding through the program to ensure consistent stick-out length and reduce arcing spatter

2. Adjust the welding posture to flat welding to ensure that the weld seam is full without undercut

3. Add crater current to reduce shrinkage defects

4. Single-station and multi-workpiece welding can be carried out, and the welding cycle can reach 4-5s/piece, which can more than double the efficiency
