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. Problems and solutions Welding of cylinder end cover: Recommended model 350GL4 Problem pictures Problems and reasons Countermeasures for Panasonic electric welding machine Pores: 1. Unstable wire feeding leads to unstable arc, arc jumping occurs, arc length becomes larger, and air enters 2 , The welding speed is fast, the molten pool crystallizes quickly, the gas is not easy to discharge, and pores are generated.

Pores: 1. Unstable wire feeding leads to unstable arc, arc jumping phenomenon occurs, arc length becomes larger, and air intrudes 2. Fast welding speed, molten pool crystallization is fast, gas is not easy to discharge, and pores are generated 1. The stability of wire feeding can be improved by using Panasonic's four-wheel wire feeder with encoder, and the wire feeding hose must be checked and cleaned regularly
2. Ensure that the gas protection effect is intact
Edge burn through:
1. The current is too large at the end of welding
2. The concentricity of the tooling rotary table is not good
3. The pointing position of the welding torch changes, causing the edge to burn through
1. Reduce the current at the end of welding
2. Correct the concentricity of the tooling rotary table to ensure the consistency of welding direction
