Ukulayisha kwangaphambili, okwakwaziwa ngokuba yi-precompression okanye ukucudisa kwangaphambili, linyathelo elibalulekileyo kwinkqubo ye-medium frequency inverter spot welding.Eli nqaku liphonononga ukubaluleka kokulayishwa kwangaphambili kunye nefuthe layo kumgangatho we-weld kunye nokusebenza.
Ukufezekisa ulungelelwaniso olululo lwe-Electrode:
Enye yeenjongo eziphambili zokulayishwa kwangaphambili kukuqinisekisa ukulungelelaniswa okufanelekileyo kwee-electrodes ngaphambi kokuba inkqubo ye-welding yangempela iqale.Ngokusebenzisa i-preloading force elawulwayo, i-electrodes idibaniswa kunye ne-workpieces, ukuseka i-interface ezinzileyo kunye ne-electrode-to-workpiece interface.Olu lungelelwaniso lubalulekile ekugcineni ukuhamba kwangoku kunye nokusasazwa kobushushu ngexesha le-welding, okukhokelela ekuthembekeni kunye ne-welds efanayo.
Ukuphucula ukuQhutywa koMbane:
Ukulayishwa kwangaphambili kunceda ekuphuculeni ukuhanjiswa kombane phakathi kwee-electrodes kunye nezinto zokusebenza.Ngokufaka uxinzelelo, nayiphi na into engcolileyo okanye i-oxides enokuthi ithintele ukudibanisa kombane iyasuswa okanye iphulwe, ivumela ukuhamba okungcono kwangoku.Ukuhanjiswa kombane okuphuculweyo kukhuthaza ukuhanjiswa kwamandla okusebenzayo, okukhokelela kwi-welds yendawo esebenzayo kunye neyomeleleyo.
Ukuqinisekisa uLwakhiwo lweNugget olungaguqukiyo:
Ukusetyenziswa kwamandla okulayisha kwangaphambili kunceda ukuqinisekisa ukubunjwa kwe-weld nugget engaguqukiyo kwaye echazwe kakuhle.Ukulayisha kwangaphambili kucinezela ii-workpieces, ukunciphisa ukuxhathisa koqhagamshelwano kunye nokwenza ngcono ukuveliswa kobushushu kwi-interface.Olu xinzelelo olulawulwayo luququzelela ukubunjwa kwendawo yokudibanisa ethembekileyo, ebonakaliswe ngokudibanisa okufanelekileyo kunye nokunyaniseka kwe-metallurgical.
Ukunciphisa Amanqaku e-Electrode:
Ukulayishwa kwangaphambili kunokunciphisa ukubunjwa kwamanqaku e-electrode kwindawo yokusebenza.Xa i-electrodes ilayishwe ngokufanelekileyo, uxinzelelo lusasazwa ngokulinganayo, lunciphisa amathuba okutshatyalaliswa kwendawo okanye ukumakishwa okubangelwa ngamandla amaninzi.Oku kunceda ukugcina inkangeleko yobuhle bamacandelo adibeneyo.
Ukukhuthaza ukomelela kweWeld kunye noKuhlala ixesha elide:
Ukusetyenziswa kwamandla okulayisha kwangaphambili kukhuthaza ukomelela ngokubanzi kunye nokuqina kwendawo ye-weld.Ngokuqinisekisa ukulungelelaniswa okufanelekileyo, ukuhanjiswa kombane, kunye nokwakhiwa kwe-nugget, ukulayishwa kwangaphambili kunegalelo kwi-welds kunye neempawu eziphuculweyo zomatshini, ezifana ne-tensile ephezulu kunye namandla okucheba.Oku kubaluleke kakhulu kwizicelo apho ukunyaniseka kwe-weld kunye nokusebenza kwexesha elide kubaluleke kakhulu.
Ukulayishwa kwangaphambili kudlala indima ebalulekileyo kwi-medium frequency inverter spot welding.Iqinisekisa ukulungelelaniswa okufanelekileyo kwe-electrode, iphucula ukuhanjiswa kombane, ikhuthaza ukubunjwa kwe-nugget engaguqukiyo, inciphisa amanqaku e-electrode, kwaye inegalelo kumandla e-weld kunye nokuqina.Ngokubandakanya ukulayishwa kwangaphambili njengento eqhelekileyo, abaqhubi banokufikelela kwi-welds ye-spot ekumgangatho ophezulu ngokuthembeka okuphuculweyo, iimpawu zoomatshini, kunye nokusebenza ngokubanzi.
