Kuramba kuwedzera chinhu chakajairika chinoonekwa mune yepakati frequency inverter spot welding michina.Ichi chinyorwa chine chinangwa chekuongorora hunhu hwekuramba kuwedzera uye zvazvinoreva mukushanda kwenzvimbo welding.
Heating Effect:
Chimwe chezvikonzero zvikuru zvinokonzeresa kuwedzera kwekupokana ndeye kupisa mhedzisiro panguva yewelding.Kana yakakwira ikozvino inopfuudzwa neworkpiece, kupisa kunogadzirwa nekuda kwekudzivirira kwemagetsi.Kupisa uku kunoita kuti tembiricha yeworkpiece ikwire, zvichiita kuti iwedzere kuramba kwayo.
Material Properties:
Kuwedzera kwekupokana kunogonawo kukanganiswa nezvinhu zvemukati zve workpiece.Zvimwe zvinhu zvinoratidza kuwedzera kwepamusoro kwekupokana kana zvichienzaniswa nezvimwe nekuda kwemaitiro avo emagetsi conductivity uye zvinopisa zvinhu.Semuyenzaniso, zvinhu zvine yakaderera conductivity kana yakakwirira thermal kuwedzera coefficients anowanzo kuwana kwakakosha kuramba kuwedzera.
Contact Resistance:
Chimwe chinhu chinogona kuita kuti kuramba kuwedzere kupikisa kusangana pakati pe electrode uye workpiece.Kusakwana kwe electrode kubata kana kusvibiswa kwepamusoro kunogona kukonzera kupikisa kwepamusoro, zvichikonzera kuwedzera kwekupokana kwese panguva yewelding.
Electrode Wear:
Nekufamba kwenguva, maelectrode ari mumichina yekugadzira welding anogona kupera uye kuparara.Sezvo nzvimbo ye electrode ichidzikira, nzvimbo yavo yekusangana neiyo workpiece inoderera, zvichikonzera kuwedzera kwekusangana kwekupokana uye kuramba kwese panguva yewelding.
Oxidation uye Kusvibiswa:
Kuvapo kweiyo oxidation kana kusvibiswa pane yebasa rekushanda kunogonawo kutungamira mukupikisa kuwedzera.Oxidized kana yakasvibiswa nzvimbo ine yakakwirira yemagetsi kuramba, inokanganisa kuyerera kweazvino uye zvichikonzera kuwedzera kwese kwekupokana panguva yewelding.
Resistance kuwedzera chiitiko chepakati-frequency inverter spot welding michina, inonyanya kukonzerwa nekudziya kwekuita, zvinhu zvemukati, kubata kuramba, kupfeka electrode, uye pamusoro oxidation kana kusvibiswa.Kunzwisisa hunhu uhwu kwakakosha pakugadzirisa mashandiro enzvimbo welding uye kuve nechokwadi kuti anowirirana uye akavimbika welds.Nekutarisa uye kugadzirisa zvinhu zvinoita kuti kuramba kuwedzere, vashandisi vanogona kuchengetedza inodiwa welding paramita uye kuwana emhando yepamusoro welds mumashandisirwo avo.
