Resistance spot welding inzira inoshandiswa zvakanyanya mumaindasitiri akasiyana, anosanganisira mota, aerospace, uye zvemagetsi. Iyi nzira inosanganisira kubatanidza zvidimbu zvesimbi zviviri kana kupfuura nekuisa kupisa uye kumanikidza panzvimbo dzakati. Hunhu hwenzvimbo weld hwakakosha pakuita kwese uye kusimba kwechigadzirwa chakapedzwa. Muchinyorwa chino, isu tichaongorora zvinhu zvitatu zvakakosha zvinopesvedzera kuramba nzvimbo welding uye maitiro avo pane welding process uye yekupedzisira chigadzirwa.
- Ikozvino Kusimba (Amperage)
Ikozvino kusimba, kuyerwa mumamperes, ndiyo yakakosha parameter mukupikisa nzvimbo welding. Inotarisa huwandu hwekupisa hunogadzirwa panzvimbo yewelding. Kana ikozvino yakaderera, kupisa kusina kukwana kunogadzirwa, zvichiita kuti kuve kusina simba uye kusina kukwana welds. Sezvineiwo, yakawandisa ikozvino inogona kukonzera kupisa, zvichikonzera kupisa-kuburikidza kana kukuvadzwa kune workpieces.
Kuti uwane yakakwana weld mhando, zvakakosha kuti usarudze yakakodzera ikozvino kusimba zvichienderana nerudzi rwezvinhu uye ukobvu. Welding mainjiniya uye matekinoroji anofanirwa kuverengera nekuseta ikozvino kuti ive nechokwadi chekuenderana uye akavimbika welds.
- Welding Nguva
Iyo nguva yewelding, inowanzoyerwa mumamilliseconds, chimwe chinhu chakakosha mukupikisa nzvimbo welding. Iyo inosarudza kuti nguva yakareba sei ikozvino inoyerera kuburikidza nekushanda, inokanganisa ukuru uye simba re weld nugget-yakanyunguduka uye yakasanganiswa chikamu chezvinhu.
Nguva pfupi dzewelding dzinogona kusapa kupisa kwakakwana kugadzira weld yakasimba, nepo nguva refu yakawandisa inogona kutungamira mukupfava kwemidziyo uye kuderedzwa kwesimba reweld. Kuwana kuenzana kwakakodzera kwakakosha pakuwana weld ine zvinhu zvinodiwa.
- Pressure (Electrode Force)
Dzvinyiriro, inoshandiswa kuburikidza nemagetsi emagetsi, inoita basa rakakosha mukudzivirira nzvimbo welding. Iyo inounza maworkpiece mukubatana kwepedyo, kuve nechokwadi chekubata magetsi kwakanaka uye kukurudzira kupisa kupisa. Dzvinyiriro inoshandiswa inofanira kukwana kubata zvinhu pamwe chete panguva uye mushure mekuita welding.
Kusakwana kumanikidza kunogona kutungamira kune hurombo weld mhando, sezvo zvichigona kukonzera mikaha pakati pezvishandiso kana kusakwana kwekupinda. Kune rimwe divi, kudzvanyirira kwakanyanya kunogona kukanganisa kana kukuvadza zvinhu, zvichikanganisa kuperera kwechimiro.
Mukupedzisa, kunaka kwekupokana kwenzvimbo welding kunokonzerwa zvakanyanya nezvinhu zvitatu zvakakosha: ikozvino kusimba, nguva yewelding, uye kudzvanywa. Kuenzanisa aya maparamendi kwakakosha kuti uwane welds inosangana nezvinodiwa zvekusimba, kusimba, uye kutaridzika. Welding vanoshanda nemainjiniya vanofanirwa kunyatso tarisa zvinhu izvi uye kuramba vachizvitarisa uye nekuzvigadzirisa kuti ive nechokwadi chezvakanakisa zvinogoneka zvewelding mukushandisa kwakasiyana.
