Chitoliro chachitsulo cha A333-6 ndi chitsulo chotsika kutentha.The osachepera kutentha 70 ° C. Nthawi zambiri normalized kapena normalized ndi mtima boma katundu.
A333-6 zitsulo za carbon ndizochepa, kotero kuumitsa chizolowezi ndi chizolowezi chozizira chophwanyika ndizochepa.Zofunika kuuma ndi ductility ndi bwino, zambiri zovuta kutulutsa kuumitsa ndi ming'alu, weldability wabwino, optional W707Ni elekitirodi ndi El katundu wa waya TGS 1N, ntchito argon ITU kuwotcherera.Kuonetsetsa kulimba bwino kwa welded mfundo.
Preheat
Pamene yozungulira kutentha ndi pansipa 5 ° C chofunika weldment preheating.Preheat kutentha kwa 100-150 oC: Preheat kuchuluka kwa welds mbali iliyonse ya 100 mm;kutentha kwa moto wa oxyacetylene (lawi losalowerera ndale) kutentha kwa cholembera choyezera kutentha kwa 50 ~ 100 mm kuchokera pakati pa chowotcherera.The muyeso mfundo uniformly anagawira, kuti bwino kulamulira kutentha.
