Ongororo yeMagetsi Resistivity muMedium Frequency Inverter Spot Welding Machines

Magetsi resistivity ndiyo yakakosha parameter mune yepakati frequency inverter spot welding machines, sezvo inosarudza kugona kwezvinhu kuramba kuyerera kwemagetsi azvino. Ichi chinyorwa chine chinangwa chekuongorora iyo pfungwa yemagetsi resistivity uye kukosha kwayo mumamiriro ekushanda kwespot welding uchishandisa medium frequency inverter michina.

1. Kunzwisisa Electrical Resistivity: Electrical resistivity, inoratidzwa nechiratidzo ρ (rho), chinhu chenyama chinoratidza kuramba kwayo kuyerera kwemagetsi emagetsi. Inotsanangurwa sereshiyo yendima yemagetsi inoshandiswa pane imwe nyaya kune inoguma yemagetsi ikozvino density. Resistivity inowanzoyerwa muzvikamu zve ohm-mita (Ω·m) kana ohm-masentimita (Ω·cm).
2. Kukosha kweMagetsi Resistivity muSpot Welding: Mukati-frequency inverter spot welding machines, kunzwisisa kusimba kwemagetsi kweiyo workpiece zvinhu kwakakosha nekuda kwezvikonzero zvakati: a. Kusarudzwa Kwezvinhu: Zvishandiso zvakasiyana zvine kupesana kwemagetsi, izvo zvinogona kukanganisa maitiro ekushongedza. Kusarudza zvinhu zvine resisitiv inowirirana inovimbisa kushanda kwazvino kuyerera uye kwakaringana kupisa chizvarwa panguva yewelding. b. Joule Heating: Spot welding inotsamira pakushandurwa kwesimba remagetsi kuita kupisa kuburikidza nekudzivirira kudziyisa. Iyo resistivity yezvigadzirwa zve workpiece inotarisa huwandu hwekupisa hunogadzirwa panzvimbo yewelding, inokonzera zvakananga weld quality uye simba. c. Kugovera Kupisa: Kusiyanisa muresitorendi kunogona kutungamira kune isina-uniform kupisa kugovera panguva yekupisa nzvimbo. Zvishandiso zvine maresitorendi akasiyana zvinogona kuratidza kupisa kusina kuenzana, zvichikanganisa saizi uye chimiro che weld nugget uye zvinogona kukanganisa kutendeseka kwakabatana. d. Bata Resistance: Iyo yemagetsi resistivity pa electrode-workpiece interface inopesvedzera kuramba kubata. Yepamusoro resistivity inogona kukonzera kuwedzera kwekubata kuramba, kukanganisa ikozvino kutamiswa uye kupisa chizvarwa.
3. Zvinhu Zvinokanganisa Magetsi Resistivity: Zviitiko zvakawanda zvinopesvedzera kusimba kwemagetsi emidziyo inoshandiswa mukukwesha nzvimbo: a. Material Maumbirwo: Iyo yekutanga kuumbwa uye kusachena zvirimo zvezvinhu zvakanyanya kukanganisa resistivity yayo. Zvishandiso zvine mwero wehutsvina wakakwira zvinowanzo ratidza resistivity yepamusoro. b. Tembiricha: Kudzivirirwa kwemagetsi kunotsamira tembiricha, nemidziyo yakawanda inoratidza kuwedzera kwekudzivirira sezvo tembiricha inokwira. Naizvozvo, zvakakosha kuti titarise tembiricha yekushanda panguva yekushivirira kwemavara kuti uongorore nemazvo resistivity mhedzisiro. c. Chimiro chezviyo: Chimiro chezviyo uye crystalline kurongeka kwezvinhu zvinogona kukanganisa simba ravo remagetsi. Zvinhu zvakatsetseka-zviyo zvinowanzo ratidza kushomeka kwepasi pane zvakakora-grained zvinhu. d. Alloying Elements: Kuwedzerwa kwealloying zvinhu zvinogona kushandura resistivity yemagetsi yezvinhu. Yakasiyana alloy maumbirwo anogona kukonzera akasiyana resistivity mazinga, zvichikanganisa maitiro ekushongedza.

Kunzwisisa iyo pfungwa yemagetsi resistivity uye kukosha kwayo mune yepakati frequency inverter spot welding michina kwakakosha kuti uwane yakakwana weld mhando uye kuita. Nekufunga nezve resistivity yemagetsi yezvishandiso zvebasa, vagadziri vanogona kusarudza zvinhu zvakakodzera, kudzora kupisa kugovera, kuderedza kupikisa kupikisa, uye kuve nechokwadi chekuyerera kwazvino panguva yewelding process. Ruzivo urwu runofambisa dhizaini uye kushanda kwenzvimbo welding masisitimu, zvinozotungamira kune akavimbika uye emhando yepamusoro welds mune akasiyana maindasitiri ekushandisa.
