摘要
为保证整车的密封性,满足日益严格的NVH与防锈要求,需在焊缝间涂布点焊密封胶。介绍了点焊密封胶分类、使用工艺及性能。实际生产经验表明,选择合适的点焊密封胶、固化工艺及涂胶量,对保证整车品质和性能具有重要作用。
The spot welding sealant should be applied within the welding joints to ensure the leak and air tightness of the finished automobiles and meet the increasingly stringent requirements of NVH and rust prevention.The classification,using process and performance of the spot welding sealants were introduced.The actual production experience showed that the selection of suitable spot welding sealants,curing process and sealant spreading has an important role to assure the quality and performance of the finished aotomobiles.
