车辆行驶过程中,底盘存在异响,经检查发现催化转化器总成焊道开裂,伴随顾客消费理念的的不断提升,追求方向的不断转换,对于产品要求也在不断升级,对驾驶舒适性、零部件的使用寿命也提出了更高要求,对于个人维权有了新的认识,同时国家对汽车排放有了越来越严的要求。通过对故障件现象的宏观确认结合金相分析测试结果对氧催化转化器焊道开裂进行分析测试确认,并进行优化。
Vehicles in the process of running, the chassis there is abnormal sound, the inspection found catalytic converter assembly weld cracking, with the customer’s consumer concept continues to improve, the pursuit of continuous conversion, the product requirements are also escalating, the driving comfort, Parts of the service life also put forward higher requirements for personal rights have a new understanding, at the same time the state has more stringent requirements on vehicle emissions. Through the macroscopical confirmation of the phenomenon of faulty parts combined with the metallographic analysis test results, the cracking of the oxygen catalytic converter weld crack is analyzed, tested, confirmed and optimized.
