Injin Welding SeamƘa'idar Aiki
The aiki manufa na wani kabu waldi inji dogara ne a kan asali najuriya waldi, amma ƙwararre ce don samar da ci gaba mai ɗorewa, ɗigogi - m waldi (kabu) tsakanin zanen ƙarfe biyu ko fiye da suka mamaye.
1. Core Principle: Resistance Seam Welding
A jigon sa, walda ɗin kabu shine bambancinjuriya waldi. Yana aiki a kan ka'idarJoule dumama: lokacin da babban wutar lantarki ya wuce ta cikin wani abu mai juriya na lantarki, yana haifar da zafi.
Asalin tsarin zafin da ake samarwa shine:H = I² * R * t
Inda:
H= An samar da zafi (Joules)
I= Wutar lantarki (Amperes)
R= Juriya na lantarki na kayan aikin (Ohms)
t= Lokacin da ake amfani da na yanzu (na daƙiƙa)
Makullin shine mafi girman juriya yana adubawatsakanin zanen karfe guda biyu (saboda rashin lahani na sama da oxides), yana haifar da madaidaicin wurin don zafi sama da yawa kuma ya zama narkakkar, samar da walƙiya.
2. Mabuɗin Abubuwan Da Aka Haɓaka & Matsayin Su
Na'urar waldawa ta kabu tana haɗa abubuwa masu mahimmanci da yawa don aiwatar da wannan ka'ida ta ci gaba:
- Wuraren Electrode (Roller Electrodes):Waɗannan suna maye gurbin na'urorin lantarki a tsaye na mai walda tabo. Suna jujjuya, faifan faifan alloy na jan karfe mai siffa{1} wanda ke manne kayan aikin kuma yana ɗaukar walda. Suna amfani da matsi na ƙirƙira da jigilar kayan aikin ta cikin injin.
- Samar da Wutar Lantarki & Mai Kulawa:Yana ba da kuma daidaita daidaitaccen ƙarfin wutar lantarki mai girma{0}amperage. Ana amfani da injinan zamaniTsakanin - Mitar Kai tsaye na Yanzu (MFDC)inverters don ingantaccen iko da inganci.
- Tsarin Matsi:Yana aiki daidaitaccen ƙarfi da daidaitacce (ta hanyar pneumatics ko servomotors) zuwa ƙafafun lantarki, yana tabbatar da kyakkyawar hulɗar lantarki da ƙirƙira narkakkar karfe.
- Tsarin sanyaya:Yana kewaya ruwa ta hannun lantarki da tasfotoci don cire babban zafi da aka haifar da kuma hana lalacewa.
3. Mataki -ta -Tsarin Aiki
Ana iya ganin tsarin a cikin jadawali mai zuwa, wanda ke zayyana manyan hanyoyin aiki guda biyu:
- Cigaban Kabu:Motocin lantarki suna jujjuya su akai-akai yayin da halin yanzu ke gudana akai-akai, suna ƙirƙirar walda guda ɗaya mara yankewa. Wannan ya dace don samar da haɗin gwiwa mai kyau don kwantena, tankuna, ko bututu.
- Mirgine{0}Spot (Matsakaici) Kabu:Na'urar tana aiki a farkon zagayowar tasha. Tayoyin suna jujjuya ɗan gajeren nesa ("fiti"), tsayawa, sannan ana isar da bugun bugun jini na yanzu{2}}kamar mai walda tabo{3}}kafin maimaitawa. Wannan yana ƙirƙira jerin gwanon walda masu haɗaka. Wannan hanya ta zama gama gari inda ci gaba da hatimi ba lallai ba ne, saboda yana rage shigar da zafi kuma yana rage murdiya.

5. Aikace-aikace na gama gari
Kabu waldishine ma'auni na masana'antu don kowane aikace-aikacen da ke buƙatar ci gaba, ɗigogi{0} haɗin gwiwa:
- Mota:Tankunan mai, tsarin shaye-shaye, mufflers, matattarar mai, masu juyawa.
- Masana'antu:Tasoshin matsa lamba, na'ura mai aiki da karfin ruwa cylinders, refrigeration sassa (compressors, evaporators), jigilar kaya da ganga.
- Jirgin sama:Layukan mai da ƙananan tankuna.
- Kayayyakin Mabukaci:Gidajen kayan aiki (misali, tankuna masu dumama ruwa, bututun injin wanki).
