Comprehensive optimization scheme for the indentation depth of the exposed solder joint of a vehicle door
In order to improve the overall welding quality of the automobile,increase users'satisfaction with the use of automobile products.Based on the debugging process of the indentation depth of the exposed soldering joints of a car door assembly,the causes of the poor appearance of the exposed soldering joints of the car door assembly were analyzed from five aspects:man,machine,material,method and ring and the following effective methods to control the poor appearance of the Solder joints were summarized:adjust the welding posture of the robot,control the electrode orientation of the welding gun,improve the grinding shape and grinding posture,optimize the surface oil of the raw material,modify the parameters of the welding machine,and set the flow range of welding circulation water.The test shows that the comprehensive treatment regimen can effectively improve the appearance of the door's exposed welded joints,reduce the extent of user complaints,and thus increase vehicle sales and promote the rapid development of national brands.
