Abstract： In response to the problem of significant fluctuations in the Y-direction dimension of the door， this paper analyzed the influencing factors one by one by using an online measurement system Perceptron， and identified key factors such as the impact of key welding point positions and mismatched under copper welding operation. 2 optimizations were carried out： firstly， by adding a welding plier guiding mechanism to optimize the key welding spot positions; secondly， by adjusting the height of the support block for the under copper welding and optimizing the adhesion between the support surface and the outer panel， the problem of Y-direction dimensional instability of door is solved.

Key words： Y-direction dimensional stability， Online measurement system， Key welding point position， Under copper welding equipment
