Maitiro Ekuona Weld: Kutevedzana Kwekudzora
Vashandi vanotevedzera kutevedzana kwakatarwa. Bhokisi rekudzora rinoverenga nguva yedanho rega rega.
Nguva yekudzvanya — maerekitirodhi anovhara uye anovaka simba risati rasvika, achigara pamachira uye achidzikamisa kubatana.
Nguva yekuweld — magetsi anopfuura nemudura, uye kupisa kunodzivirira magetsi kunowedzera nugget.
Nguva yekubata — magetsi anomira asi simba rinoramba richienderera mberi; nugget inosimba kana yamanikidzwa.
Nguva yekurega kushanda — maerekitirodhi anodzokera shure uye chishandiso chebasa chinofambira mberi, zvichiisa mwero wekutenderera.
Nguva yekuwedera inotanga yoga mushure menguva yekudzvanya. Nguva yekubatirira inouya mushure menguva yekupisa, uye nguva yekudzima inovhara denderedzwa. Aya maparamendi ekuwedera espot welding — squeeze, weld, hold, off — anoisa maparamendi ekuwedera espot yejoinhi yakapihwa. Mhinduro yeclosed-loop inoyera welding current ne shunt resistor kana Hall sensor. Izvi zvinokunda open-loop timing-only setups nekuti inogadzirisa electrode wear uye tab oxidation. Current transformer inopa imwe sarudzo yakaparadzana. Sisitimu yekudzora inogadzirisa fireing kuti ibate chinangwa.
Dhizaini Yekugadzira
Kubata mains inrush uye surge kunoda kutariswa nekukurumidza. Chinovhara varistor pamwe neTVS chinodzivirira kumberi. Heatsinking inofanira kufukidza zvese zvishandiso zvemagetsi nemaelectrodes, sezvo thermal cycling inofukidza matips nema solder joints zvakafanana. Spot welding pressure settings inoshanda nenguva iripo neye weld, saka tarisa zvese zvitatu pamwe chete. DFM constraints shape busbar layout uye copper weight. Chengetedza creepage uye clearance yakawanda parutivi rwe high-voltage. Sound resistance welding inosanganisa nguva pfupi ye weld nesimba rakakwana. Muchina wega wega welding spot unopa mubairo we board design yakangwarira. Maitiro e welding spot anoramba achidzokororwa kana electronics ichibata zvinangwa zvayo.
Kuenzanisa Maitiro Ekudzora uye Kuchinjana Kwemagadzirirwo
Arc vs. Spot: Misiyano mikuru
Sisitimu yekudzora kupinza kwearc inodzora kugadzikana kwearc, current, uye voltage. Mutongi wekugadzirisa nzvimbo anodzora kumanikidzwa kwemagetsi, nguva, uye electrode. Maitiro ekugadzirisa nzvimbo anoda plasma column yakagadzikana, saka mutongi wekugadzirisa nzvimbo anogadzirisa voltage ne current kakawanda pasekondi. Maitiro ekugadzirisa nzvimbo anoenderana nekupisa kunobva pakudzivirira kwemagetsi panzvimbo inodzima. Pano mutongi anoyera nguva yekurova kwemagetsi uye anochengetedza kumanikidzwa kwekugadzirisa nzvimbo.
Magadzirirwo ewelding espot welding — squeeze, weld, hold, and off — haana arc equivalent. Asi masisitimu eArc anobata waya, kumhanya kwekufamba, uye kureba kwearc. Muchina wewelding spot unopfura pulse imwe chete papoindi. Sisitimu yeArc inomhanya isingamire pamusono. Misiyano iyi inoumba dhizaini yebhodhi. Mabhodhi eArc anoda ma "current loops" anokurumidza. Mabhodhi eSpot anoda ma "counters" chaiwo e "weld time", uye nguva yeweld ne "current" zvinofanira kutevedzana.
