Spattering, inozivikanwawo sewelding spatter kana weld splatter, chinhu chinowanzoitika panguva yekugadzira simbi mumichina yewelding. Inoreva ejection yeakanyungudutswa simbi zvidimbu zvinogona kukanganisa kunaka weld uye nzvimbo dzakatenderedza. Ichi chinyorwa chine chinangwa chekupa tarisiro yekusapfava mumichina yekukweshesa nuts, zvikonzero zvayo, uye zvingave zvigadziriso zvekudzikisa mhedzisiro yayo.
- Zvinokonzeresa Kuputika: Zviitiko zvakati zvinogona kuita kuti risapure panguva ye nut spot welding. Kunzwisisa zvikonzero izvi kwakakosha pakuziva uye kugadzirisa nyaya yacho nemazvo. Zvimwe zvikonzero zvinozivikanwa zvinosanganisira:
a. Nzvimbo dzakasvibiswa: Kuvapo kwetsvina, mafuta, ngura, kana zvimwe zvinosvibisa pane nati kana nzvimbo yebasa zvinogona kukonzera kupfira.
b. Kurongeka kwe electrode kusina kunaka: Kusaruramisa pakati pe electrode uye nut / workpiece inogona kukonzera kusagadzikana kwearc kugadzirwa, zvichiita kuti iparadze.
c. Kusakwana kwe electrode pressure: Kusakwana electrode pressure inogona kukonzera kutadza kubata magetsi, zvichikonzera kurovanisa kwakashata nekumwaya.
d. Yakawandisa ikozvino kana voltage: Kuremedza welding wedunhu neakawandisa ikozvino kana voltage inogona kutungamirira kune yakawandisa kupisa chizvarwa uye kuwedzera kupfapfaidza.
- Mitigation Strategies: Kuderedza kana kudzivirira kupfachura panguva yekugadzira nzungu, funga kushandisa nzira dzinotevera:
a. Kugadzirira kwepamusoro: Ita shuwa kuti nati uye nzvimbo dzebasa dzakachena, hadzina zvinosvibisa, uye dzakanyatsocheneswa pamberi pewelding.
b. Electrode alignment: Ona kuti maelectrodes akanyatsoenderana nenati/workpiece, kuve nechokwadi kugadzikana kwearc kuumbwa uye kuderedza kuparadzira.
c. Optimal electrode pressure: Gadzirisa kudzvanywa kwe electrode zvinoenderana neyakakurudzirwa zvirevo kuti uwane kwakaringana kubatwa kwemagetsi uye kuderedza kusasa.
d. Yakakodzera magadzirirwo ezvino uye magetsi: Shandisa yakakurudzirwa ikozvino uye magadzirirwo emagetsi kune chaiyo nut uye workpiece zvinhu kudzivirira kupisa kwakanyanya uye kusasa.
e. Shandisa anti-spatter coatings: Kuisa anti-spatter coating pane nati uye workpiece nzvimbo inogona kubatsira kuderedza kunamatira kwe spatter uye kurerutsa post-weld kuchenesa.
f. Kugara uchigadzirisa midziyo: Ita zvechinyakare kugadzirisa pamushini we nut spot welding, unosanganisira kuongorora electrode, reconditioning, kana kutsiva, kuti ive nechokwadi chekushanda kwakakwana uye kuderedza kuparadzira.
Kusvipa panguva yekugadzira nut spot welding kunogona kukanganisa kunaka kweweld nenzvimbo dzakatenderedza. Nekunzwisisa zvinokonzeresa kuparadzira uye kuita nzira dzakafanira dzekudzikisa, vashandisi vanogona kuderedza kuumbwa kwe spatter uye kuwana emhando yepamusoro welds. Izvo zvakakosha kuti uchengetedze nzvimbo dzakachena, kurongeka kwakaringana kwe electrode uye kudzvanywa, uye yakaringana yazvino uye voltage marongero kudzikisa kuparadzira uye kunatsiridza kuita kwese welding. Kugara kugadziridzwa kwemidziyo uye kuomerera kune zvakanakisa maitiro kwakakosha pakubudirira kugadzirwa kwe nut spot welding.
