ER70S-4
ER70S-4 - uglerodli po'latdan gazdan himoyalangan payvandlash paychalarining. Himoya gazli payvandlash sifatida Ar + Co2 aralash gazidan foydalanilganda payvandlash jarayonining ajoyib ko'rsatkichlariga ega. Payvandlash paytida yoy barqaror bo'lib, chayqalish kichikdir, bu yupqa plitalarni yuqori tezlikda payvandlash uchun ishlatilishi mumkin. Kichik oqim oralig'ida kamon hali ham juda barqaror va vertikal pastga payvandlash uchun ishlatilishi mumkin. Aralashtirilgan gaz bilan himoyalangan payvandlash bilan yotqizilgan metallning mustahkamligi biroz yaxshilanadi. Tegishli quvvat darajasidagi konstruktiv po'latni payvandlash uchun ishlatiladi, u yupqa plitalar va quvurlarni yuqori tezlikda payvandlash uchun ishlatilishi mumkin.
