• Karfe mai amfani da iskar gas: Ana amfani da iskar oxygen (O₂) a matsayin iskar gas mai taimako, amma ana buƙatar a sarrafa matsin lamba. A matakin hudawa, ana iya amfani da ƙaramin matsin lamba (0.5-1bar) da farko, sannan a canza matsin lamba na yankewa zuwa babban matsin lamba (1.5-2.5bar) bayan shiga don guje wa yawan iskar oxygen don samar da adadi mai yawa na slag.
• Karfe mai bakin ƙarfe/ƙarfe: yi amfani da nitrogen (N₂) ko iska, yi amfani da matsakaicin matsin lamba da ƙarancin ƙarfi (6-10bar) don hudawa, sannan ka canza zuwa babban tsarkin nitrogen mai yawan matsi bayan shigar ciki.

2. Jinkirin iskar gas da kuma rufewa da wuri

• A canza iskar gas kafin a kammala huda ramin: a canza zuwa sigogin iskar gas don yankewa lokacin da ake gab da kammala shigar ciki don taimakawa wajen hura tarkacen da ke cikin ramin.
• Ƙara lokacin busar iskar gas: busar da daƙiƙa 0.5-1 kafin busarwa don tsaftace yankin ramin da kuma sanyaya kayan da ke kewaye.

Daidaita Matsayin Mayar da Hankali da Bututun Hannu

1. Matsayin mayar da hankali

• Lokacin da ake huda rami, yi amfani da ƙaramin adadin cire ido (mafitar tana ƙasa da saman farantin) don ƙara buɗewa da kuma sauƙaƙa fitar da slag. Misali, ƙarfe mai girman 20mm na carbon zai iya saita wurin mayar da hankali zuwa 3-5mm a ƙasan farfajiyar.
• Bayan an shiga ciki, a daidaita mayar da hankali zuwa mafi kyawun matsayi bisa ga buƙatun yankewa.

2. Zaɓin bututun ƙarfe da tsayi

• Yi amfani da manyan bututun ƙarfe masu diamita (kamar φ2.0-φ3.0mm) don haɓaka ɗaukar iskar gas da kuma haɓaka fitar da iskar gas.
• Tabbatar cewa tsayin bututun yana da matsakaici (yawanci 1.0-2.0mm) don guje wa yaduwar iskar gas da ke haifar da lalacewa mai yawa da kuma lalacewar da ke haifar da ƙarancin iska.

Tsarin tsari da ƙwarewar shirye-shirye

1. Ramin gubar da aka riga aka haƙa

• Ga faranti masu kauri sosai (misali, sama da 30mm), ana iya haƙa ƙananan ramukan matukin jirgi ta hanyar injiniya da farko, sannan a fara yanke laser daga ramukan matukin jirgi don guje wa huda kai tsaye.

2. Saita matsakaicin wurin hudawa

• Lokacin da ake tsara shirye-shirye, a sa wurin huda ya karkata daga ainihin layin kwane-kwane da 1-2mm, sannan a matsa daga wurin da aka rage zuwa layin kwane-kwane yayin yankewa don guje wa yankin tarin ragowar.

3. Inganta hanyar yanke hanya

• Ana amfani da ramuka masu karkace ko wuraren da za a fara yankewa don yaɗa slag ɗin zuwa yankin da ba a yanke shi ba.

Duba kayan aiki da kulawa

1. Yanayin Laser

• A duba ko ƙarfin fitarwa yana da ƙarfi, a tabbatar da cewa ruwan tabarau/ madubin kariya yana da tsabta, kuma a guji samun isasshen hudawa sakamakon raguwar kuzari.

2. Tsarkakewar iskar gas da kwarara

• Tabbatar da tsaftar iskar gas (musamman nitrogen/oxygen), kuma a riƙa duba ko hanyar iskar gas ɗin ta toshe ko kuma tana zubewa.

3. An daidaita bututun bututun da kayan gani.

• A daidaita daidaiton bututun da kuma hasken laser akai-akai don tabbatar da daidaiton kwararar iskar gas.

Kayan Aiki da Abubuwan Muhalli

1. Maganin saman farantin

• Tsaftace tsatsa, tabon mai ko shafi a saman farantin kafin a yanka don rage shigar ƙazanta cikin amsawar.

2. Faɗin faranti

• Tabbatar cewa farantin yana da faɗi kuma a guji gibin da ke haifar da zubewar iskar gas da kuma nuna kuzari.

Shawarar tsarin gyara sigogi

1. Da farko, gyara wasu sigogi, a hankali a daidaita lokacin da aka huda da ƙarfin, a lura da adadin slag da aka samar, sannan a nemo wurin daidaita ma'auni.

2. Yi rikodin sigogin ingantawa kuma ka kafa bayanan tsari na kayan/kauri daban-daban.

3. Gwaji da tabbatarwa: ana gudanar da gwaje-gwaje da dama na hudawa a kan kayan sharar don tabbatar da cewa an rage tarkacen kafin a yanke su bisa doka.

Takaitawa: Dubawa cikin Sauri na Mahimman Mahimman Mahimmai

Ta hanyar cikakken gyaran da ke sama, za a iya rage yawan ragowar ramin da ke huda farantin sosai, kuma za a iya inganta ingancin yankewa da inganci. Idan matsalar ta ci gaba, ana ba da shawarar tuntuɓar masana'antar kayan aiki don gwajin kayan aiki ko tallafin tsari.
