| Abstract: | One new method to improve life of spot welding electrodes for galvanized steel sheets,cryogenic treat-ment,is presented.Comparative tests on their life of cryogenic treated electrodes and non-cryogenic treated electrodes are done,and effects of different cryogenic treatments on electrode's life are compared.It is shown by results that cryogenic treatment can improve the working life of spot welding electrodes for galvanized steel sheet evidently,and different cryo-genic treatment process has different effect on electrode's life;cold insulation temperature has greater impact on its life,and cold insulation time has smaller impact on it.Cryogenic treatment process of electrodes and the test procedure of elec-trode's workin g life are introduced in the paper.Topic words :Steel sheet,Spot welding,Electrode,Cryogenic testing |
