O'rtacha chastotaspotli payvandlash mashinasikuchlanishni nazorat qilish texnologiyasi lehim birikmasini shakllantirish jarayonida nazorat ob'ektlari sifatida elektrodlararo kuchlanish egri chizig'ida ma'lum xarakterli parametrlarni tanlaydi va bu parametrlarni nazorat qilish orqali lehim birikmasining nugget hajmini nazorat qiladi. Nuqtali payvandlash jarayonida metall erish va qotib qolish evolyutsiyasidan o'tadi, payvandlash zonasining o'tkazuvchanligi va o'tkazuvchanligi ma'lum qoidalarga muvofiq o'zgaradi va elektrodlar orasidagi kuchlanish ham shunga mos ravishda o'zgaradi.
Joriy kanalning maydoni tez o'sib bormoqda. Metall erishi bilan, bir tomondan, qarshilik kuchayadi, boshqa tomondan, oqim kanalining maydoni oshadi, impedans kamayadi va kanal maydoni juda tez kengayadi va shu bilan tushuvchi egri chiziq hosil qiladi. nugget ma'lum darajada o'sganda AB ning. Agar u juda tez o'ssa, chayqalish paydo bo'ladi va kuchlanish keskin pasayadi. Kuchlanish egri chizig'ida nugget uzunligini ifodalay oladigan xarakterli parametrlar quyidagilardir: kuchlanish qiymati (V), kuchlanish farqi (V=VV), kuchlanishning o'zgarish tezligi (AVN.) va kuchlanish egri chizig'i bilan o'ralgan maydon (V). ).
Elektrod bosimi ortib, o'ngga harakat qilganda u kamayadi. Payvandlash oqimi katta bo'lsa va elektrod bosimi kichik bo'lsa, katta AV qiymatini olish mumkin. Bu qoida nugget hajmini o'zgartirish qoidasiga mos keladi. Bu shuni ko'rsatadiki, kuchlanish nazoratini qo'llashda oldindan belgilangan V ni tanlash payvandlash spetsifikatsiyasining kuchini hisobga olishi va takroriy sinovlar orqali aniqlanishi kerak.
Bir vaqtlar ishlab chiqarishda kuchlanishni o'zgartirish tezligi va kuchlanishni integratsiyalash usuli kabi sifat nazorati usullari ishlatilgan. Elektrod bosimi juda katta bo'lmagan taqdirda, kuchlanish monitoringi texnologiyasi payvandlash oqimi va chekka masofadagi o'zgarishlarga nisbatan yuqori sezuvchanlik va kichik dispersiyaga ega. Biroq, joriy shunt kichik nuqta masofasidan ta'sirlangan holatlarda, monitoring effekti ideal emas. .
