IV. Mataki na 3: Fitar da bugun jini - Wasan Millisecond na Sakin Makamashi
1. Tsarin Jiki na Karan gani
- Yawan fitarwa na yanzu ya kai 2000-5000A/mm², kuma fuskar sadarwar tana mai zafi nan take zuwa wurin narkewar kayan (digiri 660 don aluminum da digiri 1538 don karfe).
- Weld nugget tsari tsari:
- Karfe nakasar filastik → Juriya tarin zafi → Narkewar karfe → Rikicin ƙarfe na ruwa
2. Core Parameter Regulation
- Ikon sarrafa igiyar igiyar ruwa:
- Taguwar trapezoidal: Ya dace da manyan kayan aiki - (Copper, aluminum)
- Wave square: Ya dace da manyan kayan juriya{0} (bakin karfe, gami da titanium)
- Ƙimar haɓaka na yanzu: Ana sarrafa shi a 10-50kA/ms don guje wa spatter kayan aiki
- Lokacin fitarwa: Daidaita bisa ga buƙatun nugget (3-5ms don kayan aluminium da 8-12ms don kayan ƙarfe)
3. Gaskiyar -Fasahar Kula da Lokaci
- A Hall sensor is used to monitor the current curve, and welding is automatically terminated if the deviation is >8%.
- Mai ɗaukar hoto na infrared thermal yana ɗaukar filin zafin walƙiya nugget don tabbatar da zazzabi na ainihin yankin ya kai 80% -120% na wurin narkewar kayan.
V. Mataki na 4: Riƙe Matsi - Layin Tsaro na Ƙarshe don Ƙarfafa Ƙarfafawa
1. Metallurgical Action Mechanism
- Tsayawa 50% -80% na matsa lamba don haɓaka kwatance crystallization na ruwa karfe.
- Ramuwa don ƙaddamarwa mai ƙarfi ta hanyar nakasar filastik ( adadin diyya ya kusan 0.02-0.1mm).
2. Dabarun Inganta Siga
- Tsarin lokaci:

- Matakin aikace-aikacen matsa lamba: Haɓaka tsarin matsa lamba na servo don cimma daidaiton sarrafa matsa lamba na ± 1.5N
- Matakin fitarwa: Haɓaka janareta mai daidaitawa don rage yawan spatter da 72%
- Matakin riƙewa: Ƙirƙirar shirin riƙe matsi guda biyu{0} don rage ƙaƙƙarfan ƙima zuwa sifili
- Bayan canji, matsakaicin matsakaicin lokacin kuskure na wata gudacapacitor fitarwa tabo waldaAn rage daga 6.8 hours zuwa 0.5 hours.
VII. Jagoran Juyin Halittar Fasaha na gaba
- Hudu -Irin hanyar haɗin kai: Gane cikakken{1}}aiki na gyara kuskure ta hanyar fasahar tagwayen dijital
- Aikace-aikacen kayan abu mai wayo: Siffar ƙwanƙwasa gami da na'urorin lantarki na iya ramawa ta atomatik don asarar matsin lamba
- Femtosecond{0}}tsarin sa ido na matakin: Terahertz fasahar hoto za ta inganta daidaiton tsari zuwa matakin 0.1ms
Kammalawa
The hudu waldi matakai nacapacitor fitarwa tabo waldasamar da daidaitaccen sarkar sarrafa tsari. Ta hanyar madaidaicin ajiyar makamashi a cikin matakin caji, haɓaka dubawa a cikin matakin aikace-aikacen matsa lamba, sakin kuzarin jagora a cikin matakin fitarwa, da ingantaccen ƙarfi na walda nugget a matakin riƙewa, kamfanoni na iya haɓaka ingancin walda da inganci cikin tsari. Tare da haɓaka fasahar fahimtar hankali da sabbin kayayyaki, matakan haɗin gwiwa guda huɗu - za su haɓaka aikin walda tabo ta capacitor don shigar da sabon zamanin "madaidaicin matakin microsecond{3}}.
