| Abstract: | By analyzing reasons for reduction of l if etime of the electrode of galvanized sheet steel spot welding,the ion injectio n tungsten method is presented to improve the lifetime of the electrode of galv anized sheet steel spot welding.The method is to inject tungsten into the work end face of the spot welding electrode to improve the performance of the electro de.Experimental study on the electrode lifetime before and after tungsten inje cted are carried out,and the micro hardness of the spot welding before and afte r tungsten injected are measured.It is shown by test results that lifetime of the ion injection tungsten electrode is improved from600points to800points ,and spot welding splashing is reduced and sur-face quality spot welded is im proved. |
