Tsarin walda na sanda ya Gabatar
SMAW (Shielded Metal Arc Welding) ana kiransa walda ta sanda.Yana daya daga cikin shahararrun hanyoyin walda da ake amfani da su a yau.Shahararrensa shine saboda haɓakar tsarin aiki da sauƙi da ƙananan farashin kayan aiki da aiki.Ana amfani da SMAW akai-akai tare da irin waɗannan abubuwa kamar ƙaramin ƙarfe, simintin ƙarfe, da bakin karfe.
Yadda Aiki Welding
Waldawar sanda tsari ne na waldawar baka da hannu.Yana buƙatar na'urar da ake amfani da ita wacce aka lulluɓe a cikin juzu'i don shimfiɗa walda, kuma ana amfani da wutar lantarki don ƙirƙirar baka na lantarki tsakanin electrode da karafa da ake haɗa su tare.Wutar lantarki na iya zama ko dai madaidaicin halin yanzu ko kuma kai tsaye daga wutar walda.
Yayin da ake aza walda, murfin juzu'in wutar lantarki ya tarwatse.Wannan yana haifar da tururi wanda ke samar da iskar kariya da kuma Layer na slag.Dukansu gas da slag suna kare tafkin walda daga gurɓataccen yanayi.Har ila yau, juyi yana aiki don ƙara masu ɓarna, deoxidizers, da abubuwan haɗakarwa zuwa ƙarfen walda.
Electrodes Masu Rufe Flux
Kuna iya samun na'urorin lantarki masu rufaffiyar ruwa a cikin nau'ikan diamita da tsayi iri-iri.Yawanci, lokacin zabar na'urar lantarki, kuna son daidaita kayan lantarki zuwa kayan tushe.Nau'o'in lantarki masu rufaffiyar ruwa sun haɗa da tagulla, tagulla na aluminum, ƙarfe mai laushi, bakin karfe, da nickel.
Yawan Amfani da Walƙar Stick
SMAW ya shahara sosai a duk faɗin duniya wanda ya mamaye sauran hanyoyin walda a cikin masana'antar gyara da kulawa.Har ila yau, ana ci gaba da yin amfani da shi sosai wajen ƙirƙira masana'antu da gina gine-ginen ƙarfe, duk da cewa walƙiya mai ɗorewa tana samun karɓuwa a waɗannan wuraren.
Sauran Halayen walda na sanda
Sauran halayen Garkuwar Karfe Arc Welding sun haɗa da:
- Yana ba da duk sassaucin matsayi
- Ba shi da matukar damuwa ga iska da zane
- Inganci da bayyanar walda sun bambanta bisa ga ƙwarewar mai aiki
- Yawanci yana iya samar da nau'ikan haɗin gwiwar welded iri huɗu: haɗin gindi, haɗin gwiwa, T-joint, da walƙiya fillet.
