Nhanganyaya yekuunzwa kwehunyanzvi hweStainless simbi core corrosion pile welding.
Iyo murwi welding tekinoroji inoshandisa welding kugadzirisa pamusoro peiyo workpiece kuti isangane nekuita zvinodiwa zveiyo workpiece panguva yebasa.Iyo cord welding wire kunyunguduka kunyatsoshanda kwakakwira, zvakasara zviri nyore, kupuruzira kudiki kwazvo, turakiti rewelding rakanaka, uye rinogona kuwana kuenderera uye kwakagadzikana welding kwenguva yakareba, izvo zvinogona kuvandudza zvakanyanya kugadzirwa.
JINGLEI murwi welding core welding waya
Hydrogenation reactor inowanzo shandisa CR-MO simbi se substrate zvinhu, uye simbi isina tsvina yepakati welding waya zvigadzirwa GFS-309L (transition layer) uye GFS-347L (corrosion resistance) inonyanya kushandiswa kumadziro emukati uye pamusoro peiyo reactor.
GFS-309L+GFS-347L musanganiswa murwi welding
● Pidium welding process
Danho ①:
Chekutanga, iyo GFS-309L inotutirwa pane substrate zvinhu seyeshanduko layer kuti iite cushioning basa, izvo zvinogona kuderedza mukana wekuzotevera welding kuputika.
Danho ②:
Maviri akaturikidzana eGFS-347L emurwi welding anoshandiswa senge corrosion layer, uye ukobvu hwese hweiyo transition layer + corrosion layer inenge 7 ~ 8mm.
Danho ③:
Mushure mekugadzira kupisa kwekupisa (PWHT), mutengi anotevera anoda 665 ° C × 12H + 705 ℃ × 32h semuenzaniso.
Danho ④:
Akagadzira muchina welding kusvika pakukora kunodiwa.
