Abstract: Based on the problem of body leakage in the process of rain test of a trial production model, combined with the actual operation on site, this paper systematically analyzes and verifies the welding process, coating process, final assembly process and rain equipment, and finds out the improvement scheme of body leakage, which has achieved good results in practical application and effectively improved the product quality and customer satisfaction. It has certain reference and guiding significance for the follow-up body leakage prevention measures of newly developed models.
