Ukulungiswa kahle kwendawo kubalulekile ngaphambi kokushisela indawo ngomshini wokushisela amabala omshini wokushisela i-frequency inverter.Lesi sihloko sixoxa ngokubaluleka kokuhlanza indawo kanye nezinyathelo zokulungisa ukuze kuqinisekiswe ikhwalithi elungile ye-weld nobuqotho.
Ukususwa Kokungcola:
Ngaphambi kokushisela amabala, kubalulekile ukususa noma yikuphi ukungcola okukhona endaweni yokusebenza.Ukungcola okufana namafutha, amafutha, ukungcola, ukugqwala, noma upende kungaphazamisa inqubo yokushisela futhi kubeke engcupheni ikhwalithi yokushisela.Indawo kufanele ihlanzwe kahle kusetshenziswa izinto zokuhlanza ezifanele noma izindlela zokuqinisekisa indawo yokushisela ehlanzekile nengangcoli.
I-Surface Roughening:
Ukwakha indawo eqinile kungathuthukisa ukusebenza kwe-spot welding.Ngokwenza ama-workpiece ebusweni, indawo yokuxhumana phakathi kwama-electrode kanye nezinto zokusebenza iyanda, okuholela ekwenzeni ngcono ukuhanjiswa kukagesi kanye nokudlulisa ukushisa okungcono ngesikhathi senqubo yokushisela.Amasu anjengokuselisa isihlabathi, ukugaya, noma ukuqhumisa isibhamu angasetshenziswa ukuze kuzuzwe ubulukhuni obudingekayo.
Ukususwa Kwezendlalelo Ze-Oxide:
Izendlalelo ze-oksidi zingakheka endaweni yensimbi, ikakhulukazi ezintweni ezifana ne-aluminium noma insimbi engagqwali, engakhinyabeza inqubo yokushisela.Lezi zingqimba ze-oxide kufanele zisuswe ngaphambi kokushiselwa kwendawo ukuze kuqinisekiswe ukuhlangana okufanele kanye nokushisela okuqinile.Izihlanzi zamakhemikhali noma izindlela zemishini ezifana nokuxubha izintambo noma amaphedi abrasive zingasetshenziswa ukususa izendlalelo ze-oxide futhi zidalule izindawo ezihlanzekile zensimbi.
Ukususa amafutha ebusweni:
Ukuqinisekisa izimo zokushisela ezilungile, kubalulekile ukunciphisa indawo yokusebenza.Noma yimaphi amafutha ayinsalela, izinto zokuthambisa, noma ukungcola okungenakususwa ngokuhlanza kufanele kuqedwe kusetshenziswa ama-agent afanelekile okususa amafutha.Ukukhipha amafutha ngendlela efanele kuvimbela ukwakheka kwentuthu eyingozi noma ukufafaza ngesikhathi sokushisela, okuholela ekushiseleni okuhlanzekile nokuthembekile.
Ukomisa ubuso:
Ngemuva kokuhlanza, ukuqinisa, nokususa amafutha, kubalulekile ukuqinisekisa ukuthi izindawo zokusebenza zomiswe kahle.Umswakama noma ama-ejenti okuhlanza okusala endaweni angathinta kabi inqubo yokushisela futhi aholele kukhwalithi ephansi ye-weld.Izindlela zokomisa ezifanele, njengokumisa komoya noma ukusebenzisa umoya ocindezelweyo, kufanele zisetshenziswe ukuze kukhishwe noma yimuphi umswakama endaweni.
Ngaphambi kokubona i-welding ngomshini wokushisela i-medium frequency inverter spot, ukulungiswa okwanele kwendawo kubalulekile.Ukuhlanza ngokuphelele indawo engaphezulu, ukususa ukungcola, ukwenza indawo engaphezulu kulukhuni, ukususa izendlalelo ze-oxide, ukwehlisa amafutha, kanye nokuqinisekisa ukomiswa okufanele kunomthelela kwikhwalithi ephezulu yokushisela kanye nobuqotho.Ngokulandela lezi zinyathelo zokulungiswa kwendawo, opharetha bangakha indawo ekahle yokushisela, bathuthukise amandla okushisela, futhi banciphise ubungozi bokulimala noma ukwehluleka.
