O'rta chastotaspotli payvandlash mashinasielektrodlar odatda xromli tsirkonyum mis, berilliy bronza yoki berilliy kobalt misidan foydalanadi. Ba'zi foydalanuvchilar ham payvandlash uchun qizil misdan foydalanadilar, lekin faqat kichik partiyalarda.
Spotli payvandchilarning elektrodlari uzoq vaqt ishlagandan keyin issiqlik va aşınmaya moyil bo'lganligi sababli, kontaktning ichki qarshiligi kuchayadi va oqim kamayadi, shuning uchun tegishli elektrod materiallarini tanlash kerak. Turli materiallarni payvandlash uchun turli elektrodlar qo'llaniladi. Misol uchun, misni payvandlashda volfram elektrodlarini ishlatish kerak.
Chrome-pick mis elektrodlari o'rtaga o'rnatilgan sof volfram novda elektrodlari bilan ishlatilishi mumkin. Odatda, dispersiya bilan mustahkamlangan mis qotishmasi (Al2O3-Cu) to'g'ridan-to'g'ri ishlatiladi va uning ishlash muddati xromli misga nisbatan 5-10 baravar ko'p. Sof volframning qattiqligi nisbatan yomon. Agar uni Xitoyda qilish mumkin bo'lmasa, u odatda suyuq azot bilan ishlov beriladi.
Bu elektrod yopishib qolish fenomenini oldini oladi, payvandlash qismi sarg'aymaydi, lehim bo'g'inlari chiroyli, mukammal elektr o'tkazuvchanligi va issiqlik o'tkazuvchanligi, yaxshi yuqori harorat ko'rsatkichlari va alyuminiy oksidi mis elektrodi elektrod silliqlash bilan birlashganda katta rol o'ynashi mumkin. o'rta chastotali nuqta payvandchining funktsiyasi.
