Ukuchasana nokunxibelelana yeyona nto ibalulekileyo kwindawo yokuwelda, ngakumbi koomatshini bokuwelda be-inverter frequency.Ichaphazela ngokuthe ngqo ukusebenza kunye nomgangatho wenkqubo ye-welding.Eli nqaku liphonononga ukubaluleka kokuchasana noqhagamshelwano kunye nefuthe layo kwimisebenzi ye-welding.
Inkcazo yokuchasa uqhagamshelwano:
Ukuchasana noqhagamshelwano kubhekiselele kuxhathiso olwenzeka kumdibaniso phakathi kwee-electrode kunye nezinto zokusebenza ngexesha le-welding.Ivela ngenxa yokunxibelelana kombane okungafezekanga phakathi kweengcebiso ze-electrode kunye neendawo zokusebenza.
Izinto ezichaphazela ukunganyangeki koqhagamshelwano:
Imeko yomphezulu: Ukucoceka kunye nemeko yendawo yokusebenza ichaphazela kakhulu ukuchasana noqhagamshelwano.I-oxidation, i-contaminants, okanye i-coatment surface inokuthintela ukubunjwa koqhagamshelwano oluthembekileyo lombane, okubangelwa ukwanda kokuchasana.
Uyilo lwe-Electrode: Uyilo kunye nokuma kwee-electrode kuchaphazela indawo yoqhagamshelwano kunye noxinzelelo olusetyenziswa kwizinto zokusebenza.I-electrode eyilwe kakuhle iqinisekisa uqhagamshelwano olufanelekileyo kunye nokunciphisa ukuchasana noqhagamshelwano.
Izinto ze-Electrode: Ukukhethwa kwezinto ze-electrode kunokuchaphazela ukuchasana noqhagamshelwano.Izinto eziphathekayo ezine-conductivity ephezulu yombane, ezifana nobhedu okanye i-alloys zethusi, ngokuqhelekileyo zisetyenziselwa ukunciphisa ukuxhathisa kwi-interface ye-electrode-workpiece.
Indima yokuchasana noqhagamshelwano kwindawo yokuwelda:
Ukuveliswa kobushushu: Ukuchasana noqhagamshelwano kudlala indima ebalulekileyo ekuveliseni ubushushu ngexesha le-welding.Njengoko umbane wombane udlula kwi-interface yoqhagamshelwano, ukuchasana kukhokelela ekuveliseni ukushisa.Lo bushushu buyimfuneko ukunyibilikisa iindawo zokusebenza kunye nokwenza i-weld nugget eyomeleleyo.
Ukubunjwa kwe-Nugget: Ukuchasana ngokufanelekileyo koqhagamshelwano kuqinisekisa ukuhanjiswa ngokufanelekileyo kwamandla ombane kwiindawo zokusebenza, ukuququzelela ukubunjwa kwe-weld nugget echazwe kakuhle.Ukunganyangeki koqhagamshelwano olufanelekileyo kunokubangela ukungena ngokwaneleyo kobushushu, okukhokelela kwi-fusion engaphelelanga okanye i-welds ebuthakathaka.
Ukugqoka i-Electrode: Ukuxhatshazwa koqhagamshelwano kuchaphazela ukunxiba kunye nokuthotywa kwee-electrodes.Ukuchasana nokunxibelelana okuphezulu kunokubangela ukufudumeza kwendawo kunye nokukhawuleza ukunxiba kwe-electrode, kufuna ukugcinwa rhoqo okanye ukutshintshwa kwe-electrode.
Kwi-medium frequency inverter spot welding machines, ukumelana noqhagamshelwano kudlala indima ebalulekileyo kwinkqubo yokuwelda.Ukugcina ukuchasana koqhagamshelwano olufanelekileyo kubalulekile ekuveliseni ubushushu obufunekayo, ukukhuthaza ukubunjwa kwe-nugget, kunye nokufezekisa ii-welds ezinamandla nezithembekileyo.Uyilo olufanelekileyo lwe-electrode, ukukhetha izinto eziphathekayo, kunye nokulungiswa komphezulu weendawo zokusebenza kubalulekile ekunciphiseni ukuchasana noqhagamshelwano kunye nokuqinisekisa ukuhanjiswa kwamandla okufanelekileyo.Ngokuqonda kunye nokulawula ukuchasana koqhagamshelwano ngokufanelekileyo, abaqhubi banokuphucula ukusebenza kunye nomgangatho wemisebenzi ye-welding ye-spot inverter ye-welding ephakathi.
