Mu nut projection welding, hazvina kujairika kuti nzvimbo dze weld dziratidze kuchena kweyero mushure mekuita welding. Ichi chinyorwa chinotarisa zvinokonzeresa iyo yellowing phenomenon uye inopa mhinduro dzekudzikisa nyaya iyi, kuve nechokwadi chekugadzirwa kwemhando yepamusoro welds.
Zvinokonzera Yellowing:
- Oxidation: Iyo yero yeruvara inogona kuitika nekuda kweiyo oxidation yenzvimbo yeweld panguva yewelding process. Zvinhu zvakadai sokusakwana kudzivirira gasi kufukidzwa kana kusachena kwenzvimbo yebasa kunogona kukonzera kuratidzwa kweokisijeni, zvichikonzera oxidation.
- Kusvibiswa: Kuvapo kwezvinosvibisa, zvakaita semafuta, girizi, kana machira epamusoro pane workpiece kana nati, zvinogona kubatsira mukutsvuka kwenzvimbo dzeweld. Izvi zvinosvibisa zvinogona kusangana nekupisa kwekupisa panguva yewelding process, zvichiita kuti iparare.
- Kupisa Kwakanyanyisa: Kuwedzera kupisa kupinza kana kurebesa welding nguva kunogona kukonzera kubuda kwemavara e weld spots. Kupisa kwakanyanya kunogona kukonzera kuumbwa kwe intermetallic compounds kana kuchinja mu microstructure, zvichiita kuti chitarisiko cheyero.
Mhinduro dzekugadzirisa Yellowing:
- Kucheneswa Kwakakodzera: Nyatsochenesa workpiece uye nzungu nzvimbo usati welding kubvisa chero tsvina. Shandisa nzira dzakakodzera dzekuchenesa, senge degreasing kana solvent yekuchenesa, kuve nechokwadi chenzvimbo yakachena uye isina kusvibiswa.
- Yakakwana Shielding Gasi: Iva nechokwadi chakakwana chekudzivirira gasi kufukidzwa panguva yewelding process kuderedza kuratidzwa kune yemhepo oxygen. Izvi zvinogona kuwanikwa nekugadzirisa gasi kuyerera, optimize nzvimbo yemuromo, kana kushandisa gasi makapu kana shrouds kuwedzera gasi kudzivirira.
- Optimize Welding Parameters: Gadzirisa maparamita ewelding, seazvino, voltage, uye nguva yewelding, kuti uwane chiyero chakakwana pakati pekupisa kwekuisa uye weld mhando. Dzivisa kupisa kwakanyanya kunogona kutungamira mukushanduka kwemavara nekugadzirisa maparamita zvichienderana nerudzi rwezvinhu uye ukobvu.
- Ongorora Kuenderana Kwezvinhu: Simbisa kuwirirana pakati pechigadzirwa chebasa, nut zvinhu, uye chero machira epamusoro. Zvinhu zvisingaenderane kana machira anogona kuita zvisingadiwe panguva yewelding, zvichitungamira mukushanduka. Sarudza zvinhu zvinopindirana kana funga kubvisa machira asingaenderane usati welding.
- Post-Weld Kucheneswa: Mushure mekupedza iyo welding process, ita post-weld kuchenesa kuti ubvise chero inoyerera masara kana spatter iyo inogona kuita kuti iparadze. Shandisa nzira dzekuchenesa dzakakodzera zvichienderana nezvinodiwa zvekushandisa.
Iyo yero yeweld spots mu nut projection welding inogona kukonzerwa neoxidation, kusvibiswa, kana kupisa kwakanyanya. Nekuita maitiro ekuchenesa, kuve nechokwadi chekudzivirira gasi kufukidzwa, optimize welding paramita, kuongorora kuenderana kwezvinhu, uye kuita post-weld kuchenesa, vagadziri vanogona kudzikamisa nyaya yeyero uye kuwana emhando yepamusoro welds. Kugara kutariswa kweiyo welding process uye kuomerera kune akanakisa maitiro kuchabatsira kuona inowirirana kutaridzika kwe weld uye yakazara chigadzirwa mhando.
