摘要
Abstract
The comprehensive quality control strategy of multi-pass welding process for automobile shock absorbers with double suspender rings with metal dust cover was studied.It mainly includes the welding of piston rod and ring,the welding of dust cover,the welding of dust cover,the welding of bottom cover and oil cylinder,and the welding between the bottom cover and ring.The study in this paper effectively solves the problem of piston rod damage during convex welding of piston rod and hanging ring,the problem of dust cover burning in the welding of carbon dioxide gas protection welding,the prob-lem of spot welding of dust cover,the poor sealing and unqualified strength of bottom cover and oil storage cylinder,and the abnormal welding of bottom cover and hanging ring.The solution of the above quality problems plays a very important role in effectively protecting the surface quality of the piston rod in the manufacturing process and preventing the turning of the shock absorber(i.e.the suspension ring falls off),oil leakage and abnormal sound.The application results also further verify the effectiveness and feasibility of the proposed comprehensive quality control strategy for welding process.关键词
