Yadawa Welding Zazzabi da Matsayin Matsi

A cikin masana'antu kamar makamashi mai sabuntawa, watsa wutar lantarki, ajiyar baturi, da tsarin hotovoltaic,yaduwa waldi injitaka muhimmiyar rawa wajen kera na'urorin haɗi masu sassauƙa, sandunan wutar lantarki, na'urori masu haɗawa, da maɗaukakin abin dogaro na lantarki-.

Daga cikin dukkan sigogin tsari, zafin walda da matsa lamba na walda sune mahimman abubuwa biyu mafi mahimmanci waɗanda ke ƙayyade ingancin haɗin gwiwa, ƙarfin injina, da dorewar dogon lokaci{{0}.
Ikon sarrafa waɗannan sigogi kai tsaye yana shafar aikin samfur kai tsaye kuma yana tasiri yadda masu amfani yakamata su kimanta da zaɓi kayan aikin walda.

Wannan jagorar yana bayanin yanayin zafin jiki da kewayon matsin lamba, yadda suke aiki tare, da kuma yadda yakamata a yi la'akari da waɗannan sigogi yayin koyo game da waldawar watsawa ko zabar injin da ya dace don samarwa.

Waldawar yaɗuwar ƙaƙƙarfan tsarin haɗaɗɗiyar jiha -. Ba kamar walda ba, kayan ba su narke. Madadin haka, haɗin gwiwa yana samuwa ta hanyar yaduwar atomic a babban zafin jiki da kuma ƙarƙashin matsin lamba.

Tsarin haɗin kai ya dogara ne akan:

• Nakasar filastik a farfajiyar lamba
• Ƙara wurin hulɗa na gaske tsakanin kayan
• Ƙaurawar atomic a duk faɗin abin dubawa
• Samar da ingantaccen haɗin ƙarfe na ƙarfe
• Kawar da voids da surface oxides

Domin babu narkewa da ke faruwa, ingancin walda ya dogara ne akan:

• Isasshen zafin jiki don kunna yaduwar atomic
• Isasshen matsa lamba don ƙirƙirar kusancin ƙasa

Wannan shine dalilin da ya sa injunan waldawa yaɗuwa suna buƙatar daidaitattun tsarin sarrafa zafin jiki da tsarin kula da matsi, ba kawai babban ƙarfin fitarwa ba.

A aikin masana'antu, yawan zafin jiki na walda ana sarrafa shi a60% -80% na yanayin narkewar kayan (Tm).
Wannan kewayon yana ba da damar ingantaccen yaduwar atomic ba tare da haifar da narkewa ko lalacewar tsari ba.

A cikin waɗannan jeri, waldawar watsawa na iya samun ƙarfin haɗin gwiwa har zuwa 90% ko fiye na ƙarfin kayan tushe, tare da ingantaccen ƙarfin lantarki da kwanciyar hankali na inji.

A cikin samarwa na gaske, ana amfani da bayanan bayanan dumama matakai da yawa:

1. Mataki mai zafi - yana rage damuwa na ciki
2. Babban matakin dumama - yana kunna yaduwar atomic
3. Matsayin riƙewa - yana daidaita tsarin watsawa
4. Matsayin sanyaya mai sarrafawa - yana hana tsagewa da lalacewar tsarin

Misali, a cikin waldawar busbar tagulla-aluminum:

• Dumama a hankali daga zafin jiki zuwa digiri 300 → 500 digiri → 600 digiri
• Wannan yana hana damuwa na thermal da ke haifar da ƙimar haɓaka daban-daban
• Yana tabbatar da tsayayyen haɗin kai da daidaiton tsari

Wannan shine dalilin da ya sa ingantattun ingantattun injunan waldawa{0} dole ne su goyi bayan madaidaitan zafin jiki na shirye-shirye da daidaitawar yanayin zafi, ba kawai madaidaicin zafin jiki ba.

Matsin walda mai yaduwa yawanci ana sarrafa shi tsakanin:5-30 MPa

Madaidaicin ƙimar ya dogara da:

• Taurin kayan abu
• Kaurin abu
• Ƙunƙarar saman
• Girman yanki na lamba
• Haɗin ƙarfe iri ɗaya

Amfani da walƙiya yaduwa na masana'antumataki - ta - sarrafa matsi na mataki:

• Pre{0}matakin matsa lamba (5-10 MPa)

Yana ƙirƙira tuntuɓar farko da daidaitawa

• Babban matakin matsa lamba (15-25 MPa)

Yana haifar da nakasar filastik kuma yana ƙara yanki na ainihi

• Rike matakin matsa lamba

Yana riƙe da ingantaccen yanayin yaduwa don haɗin gwiwa

Wannan hanyar tana haɓaka ingancin haɗin gwiwa, yana hana zamewar abu, kuma yana tabbatar da ingantaccen tsarin haɗin gwiwa.

Yaduwa walda ba kawai "high zafin jiki + high matsa lamba."
Yana da asarrafawa daidaita tsarintsakanin zafin jiki da matsa lamba:

• Zazzabi yana sarrafa saurin yaduwa
• Matsi yana sarrafa ingancin lamba
• Tare suna ƙayyade ingancin haɗin gwiwa

Misalai daga aikace-aikacen makamashi:

• Tagulla-Bakin Karfe waldi:
