Gabaɗaya Abubuwan Game da Welding Electrodes
Tianqiao walda lantarki shine zaɓi na ƙwararru
Welding electrodes suna da mahimmanci, kuma yana da mahimmanci cewa mai walda da ma'aikatan da suka dace su san irin nau'in da za a yi amfani da su don ayyuka daban-daban.
Menene na'urorin walda?
Electrode wata waya ce mai rufaffiyar karfe, wacce aka yi ta da kayan irin karfen da ake waldawa.Don farawa, akwai na'urorin lantarki masu amfani da kuma marasa amfani.A garkuwa karfen baka walda (SMAW) wanda aka fi sani da sanda, na’urorin lantarki ana amfani da su, wanda ke nufin ana amfani da wutar lantarki yayin amfani da ita kuma tana narkewa da walda.A cikin Tungsten Inert Gas walda (TIG) na'urorin lantarki ba su da amfani, don haka ba sa narkewa kuma su zama wani ɓangare na walda.Tare da Gas Metal Arc Welding (GMAW) ko MIG waldi, na'urorin lantarki suna ci gaba da ciyar da waya.2 Waldawar baka mai juzu'i tana buƙatar ci gaba da ciyar da lantarki tubular lantarki mai ɗauke da juzu'i.
Yadda za a zabi walda lantarki?
Zaɓin na'urar lantarki yana ƙaddara ta buƙatun aikin walda.Waɗannan sun haɗa da:
- Ƙarfin ƙarfi
- Halittu
- Juriya na lalata
- Ƙarfe na tushe
- Weld matsayi
- Polarity
- A halin yanzu
Akwai na'urorin lantarki masu haske da nauyi.Na'urorin lantarki masu haske suna da murfin haske wanda ake amfani da shi ta hanyar gogewa, fesa, tsomawa, wankewa, gogewa, ko tumɓukewa.An lulluɓe na'urorin lantarki masu nauyi ta hanyar extrusion ko digo.Akwai manyan nau'ikan sutura masu nauyi guda uku: ma'adinai, cellulose, ko haɗin biyun.Ana amfani da sutura masu nauyi don walda baƙin ƙarfe, karafa, da saman ƙasa.
Menene ma'anar lambobi da haruffa akan sandunan walda?
Ƙungiyar walda ta Amurka (AWS) tana da tsarin ƙididdigewa wanda ke ba da bayanai game da takamaiman na'urar lantarki, kamar irin aikace-aikacen da aka fi amfani dashi da kuma yadda yakamata a sarrafa shi don ingantaccen inganci.

"E" yana nuna alamar walda ta baka.Lambobin farko guda biyu na lamba 4 lambobi da lambobi uku na farko na lamba 5 suna tsaye don ƙarfin ɗaure.Misali, E6010 na nufin fam 60,000 a kowace murabba'in inci (PSI) ƙarfin juzu'i da E10018 yana nufin 100,000 psi ƙarfi.Lamba na gaba zuwa ƙarshe yana nuna matsayi.Don haka, “1” na nufin duk na’urar lantarki, “2” na lantarki da lantarki, da kuma “4” na lantarki, a kwance, na tsaye da na sama.Lambobi biyu na ƙarshe sun ƙayyade nau'in sutura da walƙiyar halin yanzu.4

Sanin nau'ikan na'urorin lantarki daban-daban da aikace-aikacen su suna taimakawa wajen aiwatar da aikin walda daidai.Abubuwan la'akari sun haɗa da hanyar walda, kayan walda, yanayin gida/ waje, da wuraren walda.Yin aiki da bindigogin walda iri-iri da na'urorin lantarki na iya taimaka muku sanin wanne na'urar lantarki don amfani da aikin walda.
