GTAW, ERNiCr-3, nikel-xrom-molibden-kolumbiy qotishmasi, turli xil materiallarni payvandlash, plomba materiallari, payvandlash kuchi, korroziyaga chidamlilikAnnotasiya
Turli xil metallarni, xususan ferritli qotishma po‘lat va nikel qotishmalarini ERNiCr-3 prutokidan foydalangan holda GTAW va SMAW usullari orqali payvandlashga qaratilgan. Materiallarning issiqlik kengayishi, eritish harorati va metallurgik xususiyatlari keskin farq qilgani sababli ularni birlashtirish murakkab jarayon hisoblanadi. O‘tkazilgan mexanik sinovlar (cho‘zilish mustahkamligi, zarba viskozligi va qattiqlik) GTAW usuli va ERNiCr-3 prutogi bilan bajarilgan payvand choklari yuqori mustahkamlik va korroziyaga chidamlilikni ta’minlashini ko‘rsatdi. Bu natijalar muhim sohalarda ishlatiladigan konstruktsiyalarning ishonchliligini va xizmat muddatini oshirishda amaliy ahamiyatga ega
