O'rta chastotali nuqta payvandlash mashinalarining ko'p qatlamli payvandlash nuqtalariga ta'sir qiluvchi omillar

O'rta chastotaspotli payvandlash mashinalaritajriba orqali ko'p qatlamli payvandlash uchun payvandlash parametrlarini standartlashtirish. Ko'pgina testlar shuni ko'rsatdiki, payvandlash nuqtalarining metallografik tuzilishi odatda ustunli bo'lib, foydalanish talablariga javob beradi. Temperlash bilan ishlov berish ustunli donalarni yaxshilashi mumkin, shu bilan nuqtali payvandlash birikmasining mexanik xususiyatlarini ma'lum darajada yaxshilaydi.

O'rta chastotali nuqta payvandlash mashinalarining ko'p qatlamli payvandlash nuqtalariga ta'sir qiluvchi omillarga quyidagilar kiradi:

Payvandlashning termal aylanishi: Ish paytida issiqlik manbai ishlov beriladigan qism bo'ylab harakatlanadi, bu esa ishlov beriladigan qismning ma'lum bir nuqtasida harorat ko'tarilib, vaqt o'tishi bilan pasayib, yana pasayishdan oldin maksimal qiymatga erishadigan termal tsiklni keltirib chiqaradi.

Payvandlash issiqligidan ta'sirlangan zona: Payvandlash joyini o'rab turgan hudud payvandlash issiqligi, shu jumladan termoyadroviy zona, qizib ketgan zona, tavlangan zona, qisman faza o'zgarishi va boshqalar tufayli uning strukturaviy xususiyatlarida o'zgarishlarga uchraydi.

Issiq yoriqlar: Payvandlash paytida qattiq yoriqlar yaqinidagi metallda yuzaga keladigan yuqori haroratli yoriqlar, issiqlik yoriqlari yoki kristalli yoriqlar deb ham ataladi.

Sovuq yoriqlar: pastroq haroratlarda payvandlangan birikmada cheklash kuchlanishlari, söndürme tuzilmalari va vodorod tufayli yuzaga keladigan yoriqlar, shuningdek, söndürme yoriqlari deb ham ataladi.

Oldindan isitish: payvandlashdan oldin ishlov beriladigan qismning to'liq yoki bir qismini isitishni o'z ichiga olgan jarayon.

Isitishdan keyingi: haroratni saqlab turish uchun payvand chokining to'liq (yoki bir qismini) zudlik bilan isitish, payvandlashdan keyingi isitish deb nomlanuvchi, payvand chokida vodorod tarqalishini kamaytirishga qaratilgan, shuningdek, dehidrogenatsiyani davolash deb ham ataladi.

Payvandlashdan keyingi issiqlik bilan ishlov berish: payvand chokining mikro tuzilishini yaxshilash yoki qoldiq stresslarni bartaraf etish uchun payvandlashdan keyin o'tkaziladigan issiqlik bilan ishlov berish.
