Khoom Taw qhia

A270 qhia meej tias cov welded raj yuav tsum tau tsim los ntawm kev siv cov txheej txheem vuam tsis siv neeg thiab tsis muaj cov hlau muab tub lim yuav tsum tau ntxiv thaum lub sijhawm vuam. Cov raj ua haujlwm hnyav hnyav yuav tsum tau ua haujlwm txias ntawm cov raj welded kom txo cov phab ntsa thiab vuam tuab tsis pub tsawg dua 35 feem pua ua ntej qhov kawg annealing. Tsis siv neeg fillers yuav tsum tau siv nyob rau hauv vuam. Tag nrho cov khoom siv yuav tsum tau muab tso rau hauv qhov kub-kho mob. Ib ntu ntawm cov khoom siv tiaj tiaj los yog lub raj yuav tsum tau tshuaj xyuas rau txhua qhov kev kho cua sov. Txhua lub raj yuav tsum raug kuaj xyuas txhua yam xws li rov qab flattening test, hydrostatic pressure test los yog tsis muaj kev puas tsuaj hluav taws xob. Cov txheej txheem nram qab no yuav raug teev tseg: zeb tiav, tshuab polished nto tiav, No. 80 tiav, No. 120 tiav, No. 180 tiav, No. Longitudinal polishing yuav tsum tau ua nyob rau hauv lub puab nto xwb, thaum circumferential polishing yuav tsum tau ua nyob rau hauv lub puab nto, sab nrauv los yog ob qho tib si.
