Inconel 600 ni payvandlash mumkinmi?
Inconel 600 ning payvandlash xususiyatlari
Inconel 600 payvandlash odatda oldindan isitishni talab qilmaydi. Biroq, asosiy metall harorati 15 darajadan past bo'lsa, namlik kondensatsiyasi tufayli teshiklarni oldini olish uchun har ikki tomonning uzunligi 250 mm dan 300 mm gacha bo'lgan qo'shma joyni 15 dan 20 darajagacha oldindan qizdirish kerak. Donning o'sishi va karbid yog'inlarining oldini olish uchun o'tish joylarining harorati 100 darajadan yuqori bo'lmasligi kerak. Tez sovutishning oldini olish uchun ehtiyot bo'lish kerak, bu esa g'ovaklikka olib kelishi mumkin. Payvandlash joyini payvandlash ishlaridan oldin ehtiyotkorlik bilan tozalash kerak.
