Direct current (DC) welding uye alternating current (AC) welding maviri anowanzoshandiswawelding process, uye mumwe nemumwe ane maitiro ake. Muchikamu chino, tichaongorora kuti ndeupi musiyano uripo pakati peDC welding neAC welding mumunda weresistance welding, uye ndeipi yelding inobatsira zvakanyanya? Izvi zvichakubatsira kusarudza pakati pezviviri.
Working Principles:
MFDC/Inverter Welding Machine:
Chekutanga,nhatu-chikamuAC voltage inopfuura nepazvigadziriso zvekusefa.
Chechipiri,IGBTmaswichi anoshandura ikozvino kuita yepakati-frequency ikozvino ye1000 Hz uye kuiendesa kunewelding transformer.
Chekupedzisira, epamusoro-simba rectifier diode anoburitsa welding ikozvino yakagadzikana yakananga ikozvino (DC).
AC Welding Machine:
Iko kupinza kwesimba ndeye AC, iyo, mushure mekupfuura nepakati pesimba rekuchinja, inopinda mukati medunhu guru uye control circuit.
Transformer inodzika pasi pe-high-voltage AC kune yakaderera-voltage AC inokodzera welding. AC ikozvino inochinjana pakati pezvakanaka nezvakaipa, ichigadzira kupisa sezvo ichipfuura nepakati petsvimbo yewelding uye workpiece, nekudaro ichinyungudutsa welding zvinhu uye kuwana welding.
Ndeupi musiyano uripo pakati peDC welding neAC welding?
Kugadzikana
DC welding ndechimwe chezvinhu zvinozivikanwa pasi rose zvakakwirira-kumagumo kurambana welding zvigadzirwa zvine kusimba kwakasimba. Iyo welding process paramita ine hushamwari, yechipiri ikozvino ADAPTS kune yakafaranuka, uye inonyatso chengetedza inogara iripo, iyo ine yakakura application tarisiro kupfuura AC welding.
Iyo DC welding current inogadziriswa pamwero we1000 times pasekondi, ichisvika millisecond accuracy, iyo inodarika kakapetwa ka20 kupfuura kurongeka kwechinyakare AC welders.
DC welding haina kukanganiswa nechimiro uye zvinhu zveiyo workpiece, kubvisa inductance kurasikirwa. Iyo AC welding muchina uri nyore kukwenenzvera deformation kana kusasimba kusimba nekuda kwekuchinja kwechimiro cheiyo workpiece zvinhu.
Weld Splash
Iyo DC magetsi inoburitsa iyo diki waveform kudzivirira peak ikozvino kuvhunduka uye kuderedza kupuruzira panguva yewelding. Asi AC welding muwelding process inoburitsa yakawanda spatter, inokanganisa kunaka kwezvigadzirwa zvewelding.
Welding kunyatsoshanda
Iyo welding simba chinhu cheDC welding muchina inodarika makumi mapfumbamwe nesere muzana, uye iyo welding simba chinhu cheAC welding muchina ingangoita 60%, zvichiratidza kuti DC welding inoshanda yakakwira zvakanyanya kupfuura AC.
Mutengo
Nekuti kukosha kwekutanga kweDC welding ikozvino kwakawedzera zvakanyanya, iyo chaiyo welding nguva inopfupikiswa neanopfuura 20%, uye iyo nguva mutengo inochengetedzwa zvakanyanya.
Nekudaro, mumutengo wemuchina wewelding, iyo AC welding muchina ndiyo yakanyanya kutonga, uye mutengo wayo ungangove wakajairwa kana kunyange wakaderera pane DC muchina. Kana iwe uine bhajeti shoma yekutenga muchina welding, saka muchina weAC zvakare isarudzo yakanaka.
Kuchengetedza Simba
Zvinodiwa zvemagetsi efekitori zvakaderera, chete 2/3 ye AC welder, kunyangwe magetsi emagetsi achichinja, iyo DC welder inogona kuramba ichinyatso kudzora welding ikozvino. Naizvozvo, kushandiswa kwesimba kweDC welding muchina kwakadzikira zvakanyanya, uye kupfuura 40% simba rekuchengetedza rinowanikwa.
Environmental Protection
DC welding inzira yakasvibira welding inobvisa kusvibiswa kwemagetsi, haidi yakasarudzika magetsi, uye inogona kushandiswa nerobhoti welding fixture control system. Ac welding ine simba rakakura pane gidhi remagetsi, uye zviri nyore kusvibisa magetsi.
Summary
Muchidimbu, DC welding yakakura kune AC welding mune zvakawanda zvinhu. Kana uine bhajeti rakakwana, saka unofanirwa kusarudza DC welding. Pamusoro pezvo, kana iwe uchida kubatanidza zvigadzirwa zvine zvemhando yepamusoro zvinodiwa, DC muchina isarudzo yako yakanaka.
