Welding adagElectrode
Heerka: DIN 8555 (E7-UM-250-KPR)
Nooca No.: TY-C BMC
Tilmaamaha & Codsiga:
Dib u soo kabashada sare ee aasaasiga ah ee SMAW electrode
· Qaab dhismeedka austenite oo buuxa.Adkeysi aad u sarreeya iyo adkeysi sare.
Waxay ku habboon tahay daboolka qaybaha cadaadiska ugu sarreeya iyo shoogga oo ay weheliso nabar.Dusha sare waxaa lagu samayn karaa birta birta ah iyo sidoo kale austenitic adag Mn-steel iyo kala-goysyada Mn-steel adag waa la alxan karaa.
Goobaha ugu muhiimsan ee laga codsado waxay ku jiraan warshadaha macdanta iyo sibidhka, isgoyska tareenka, bambooyin biyo-mareen ah, bistoonnada hawo-mareenka, qaybta burburiyaha oo saameyn weyn ku leh macdanta jilicsan.
