Umbhobho wentsimbi we-A333-6 yintsimbi enobushushu obuphantsi.Ubushushu obuncinci be-70 ° C. Ngokuqhelekileyo isiqhelo okanye i-normalized kunye ne- tempered state umthengisi.
Umxholo wekhabhoni yentsimbi ye-A333-6 usezantsi, ngoko ke ukuqina ukuthambekela kunye nokuthambekela kokuqhekeka okubandayo kuncinci.Ukuqina kweMaterial kunye ne-ductility kungcono, ngokubanzi kunzima ukuvelisa ukuqina kunye nokuqhekeka, i-weldability elungileyo, i-electrode ye-W707Ni ekhethiweyo kunye ne-El yokungeniswa kwe-wire TGS 1N, usebenzisa i-argon ITU welding.Ukuqinisekisa ukuqina okulungileyo kwamalungu adityanisiweyo.
Ukutshisa kwangaphambili
Xa iqondo lobushushu ambient lingaphantsi kwe-5 ° C efunekayo weldment preheating.Ukushisa kwe-preheat ye-100-150 oC: Ukufudumala ububanzi be-welds kwicala ngalinye le-100 mm;ukufudumeza idangatye le-oxyacetylene (ilangatye elingathathi hlangothi) iqondo lobushushu bepeni yokulinganisa iqondo lobushushu kwi-50 ~ 100 mm ukusuka kumbindi weweld.Amanqaku okulinganisa asasazwa ngokufanayo, ukuze kulawulwe ngcono ubushushu.
