Nhanganyaya kune Spot Welding Galvanized Sheets ane Medium Frequency Inverter Spot Welding Machines.

Spot welding inzira inoshandiswa zvakanyanya yekujoinha marata mumaindasitiri akasiyana. Mashizha ane galvanized, anonziwo galvanized simbi kana zinc-coated simbi, anopa zvakanakisa kusaita ngura uye kusimba. Muchinyorwa chino, isu tichaongorora maitiro enzvimbo welding galvanized sheets tichishandisa yepakati frequency inverter spot welding michina, tichiratidza zvakakosha kufunga uye matekiniki anobatanidzwa.

1. Kunzwisisa Mashizha Akabatiswa: Marata ane galvanized mashizha esimbi akaputirwa nezinc kuti asaora. Iyo zinc coating inopa chibairo chinodzivirira simbi yepasi kuti isasangana yakanangana nenharaunda yakapoteredza, nokudaro ichideredza njodzi yekuumbwa kwe ngura. Nekudaro, kuvepo kweiyo zinc coating inokonzeresa mamwe matambudziko panguva yewelding, iyo inofanirwa kugadziriswa kuti iwane yakavimbika uye yemhando yepamusoro welds.
2. Electrode Sarudzo: Kana nzvimbo yekushongedza mashizha akabatiswa, kusarudzwa kwe electrode kwakakosha. Kunyanya kutarisisa kunofanirwa kupihwa kune electrode zvinhu uye coating kuti ive nechokwadi chekuenderana neyakagadzikiswa nzvimbo. Zvinokurudzirwa kushandisa maelectrode akagadzirwa kubva kuzvinhu zvakaita semhangura alloys kana zvinhu zvine anti-sticking properties kuderedza njodzi ye zinc adhesion kune electrode surfaces.
3. Kucheneswa uye Kugadzirira Kwepamusoro: Kucheneswa kwakaringana uye kugadzirira kwepamusoro kwakakosha pamberi pekuisa machira. Iyo zinc yekuputira pamapepa inogona kunge iine tsvina, senge mafuta, tsvina, kana oxides, izvo zvinogona kutadzisa welding maitiro uye kukanganisa weld mhando. Kunyatsochenesa uchishandisa zvinonyungudutsa zvakakodzera kana degreasers zvinodikanwa kuti ubvise chero zvinosvibisa uye uve nechokwadi chekuchenesa nzvimbo yewelding.
4. Welding Parameters: Spot welding maparamendi anoita basa rakakosha mukuwana akavimbika welds pamapepa ane galvanized. Ikozvino welding, nguva yewelding, uye simba re electrode rinoda kunyatsogadziriswa kuti rivepo kune zinc coating. Yepamusoro welding currents uye nguva dzakareba dzewelding dzinowanzodikanwa kuti ive nechokwadi chekusanganisa kwakaringana pakati pemapepa ane galvanized. Simba re electrode rinofanirwawo kugadzikwa zvakakodzera kuti rigadzirise kusangana kwakaringana uye kukurudzira kufambisa kupisa kwakakwana panguva yewelding process.
5. Post-Weld Kurapa: Mushure mekuvhara machira ane mashizha, zvakakosha kugadzirisa zvingangoitika zvine chekuita neiyo welding process. Chimwe chinonyanya kunetseka ndechekuumbwa kwe zinc spatter, iyo inogona kuitika nekuda kwe vaporization ye zinc coating panguva yekuputika. Kudzikamisa izvi, kurapwa kwemashure-weld sekubvisa zinc spatter kana kuchenesa pamusoro kungave kuri madikanwa kuti uwane yakachena uye inoyevedza weld.

Spot welding galvanized sheets uchishandisa yepakati frequency inverter spot welding michina inopa yakavimbika uye inoshanda nzira yekujoinha zvinhu izvi. Nekutarisa zvinhu zvakaita sekusarudzwa kweelectrode, kucheneswa kwakakodzera uye kugadzirira kwepamusoro, optimized welding parameters, uye post-weld kurapwa, vagadziri vanogona kuwana emhando yepamusoro welds pamapepa ane galvanized. Izvi zvinogonesa kugadzirwa kwemagungano akasimba uye asingadzivirike, zvichiita zvepakati frequency inverter spot welding michina chishandiso chakakosha mumaindasitiri anoshanda nesimbi.
