In-Depth Ongororo yeMagetsi uye Thermal Conductivity yeResistance Spot Welding Materials.

Resistance spot welding inzira inoshandiswa zvakanyanya mukugadzira, kunyanya mumaindasitiri emotokari uye aerospace. Kubudirira kwechiitiko ichi kunoenderana zvakanyanya nemagetsi uye kupisa conductivity yezvinhu zvinobatanidzwa. Muchinyorwa chino, isu tichaongorora nyika yakaoma yezvivakwa zvezvinhu izvi uye mabasa azvo akakosha mukupikisa nzvimbo welding.

Mafambisirwo eMagetsi: Kiyi yeKushanda Kwemagetsi

1. Kunzwisisa Electrical Conductivity: Electrical conductivity ndiyo chiyero chekugona kwechinhu kuitisa magetsi. Mukushivirira nzvimbo, maworkpiece (kazhinji masimbi) anofanirwa kutakura magetsi emagetsi kuti aite kupisa panzvimbo yeweld. Zvishandiso zvine yakakwirira yemagetsi conductivity, semhangura nealuminium, zvinofarirwa maelectrodes nekuti anofambisa kuyerera kwemagetsi, achigadzira yakawedzera kupisa sosi panzvimbo yekubata.
2. Basa muKupisa Generation: Kana magetsi emagetsi achipfuura nepakati pezvishandiso, kushorwa kwavo kwemagetsi kunoita kuti vapise nekuda kweJoule kupisa. Uku kupisa kwenzvimbo kunopfavisa zvinhu, zvichiita kuti zvibatanidzwe pamwe chete panzvimbo yeweld. High magetsi conductivity muma electrode inovimbisa kushoma kupisa kurasikirwa, zvichiita kuti welding process inyatsoita.
3. Kusarudzwa kwezvinhu: Mhangura uye alloys ayo, akadai semhangura-chromium uye mhangura-zirconium, isarudzo dzakakurumbira dzemagetsi emagetsi nekuda kwekunaka kwemagetsi. Nekudaro, zvigadzirwa zve electrode zvinofanirwawo kumira kushushikana kwemechani uye kupfeka panguva yekugadzira welding.

Thermal Conductivity: Bancing Heat Distribution

1. Kunzwisisa Thermal Conductivity: Thermal conductivity inoyera kugona kwechinhu kuitisa kupisa. Mukushivirira nzvimbo welding, zvakakosha kudzora kugovera kwekupisa kudzivirira warping kana kukuvadzwa kwezvishandiso. Kudzika kwekupisa kwekushisa muzvinhu zviri kusungirirwa kunobatsira kuve nekupisa mukati menzvimbo yewelding.
2. Kudzivirira Kupisa: Zvishandiso zvine high thermal conductivity, semhangura, zvinogona kukurumidza kubvisa kupisa kubva kune welding point. Nepo ichi chivakwa chinobatsira maelectrode kudzivirira kupisa, zvakakosha kushandisa zvinhu zvine yakaderera yekupisa conductivity yezvishandiso. Izvi zvinova nechokwadi chekuti kupisa kwakamira panzvimbo yeweld, zvichibvumira kubatana kunoshanda pasina kupisa kwakanyanya.
3. Kugadzirisa Misanganiswa Yezvinhu: Kuwana chiyero chakakodzera pakati pepamusoro magetsi conductivity muma electrode uye yakaderera thermal conductivity mune workpieces kwakakosha pakubudirira resistance spot welding. Mainjiniya anowanzo edza neakasiyana masanganiswa ezvinyorwa kuti awane yakaringana chiyero kune chaiyo welding application.

Mukupikisa nzvimbo welding, kunzwisisa magetsi uye kupisa conductivity yezvinhu kwakakosha pakuwana akavimbika uye emhando yepamusoro welds. Electrical conductivity inogonesa kuyerera kwazvino kwekugadzira kupisa, ukuwo kudzora kupisa conductivity kunobatsira kuchengetedza kwakaringana kupisa kwekupisa panzvimbo yewelding. Mainjiniya uye mawelder anofanirwa kunyatso sarudza uye kuenzanisa zvinhu izvi kuti zviwane mhedzisiro inodiwa mumagadzirirwo akasiyana ekugadzira.
