Riam cov tshuab thev naus laus zis rau inlaid Neeg Kho Tshuab Hl
Tam sim no cov hniav uas twb muaj lawm ntawm hlau txheej txheem tshuab ntawm cov hlau loj thiab muaj xeb ntawm lub cev thiab xeb cov pob qij txha ntawm ob los ntawm hluav taws xob vuam ua kom lawv kaw thiab airtight. Lub hom phiaj yog kom sov tag nrho cov chaw yuav tsum welded nyob rau hauv qhov siab rauv taws kub, kom lawv huv si thiab tsis oxidized. Nyob rau hauv txoj kev no, thaum lub hniav dawb nyob rau ib tug kub thiab yog dov los ntawm cov pob zeb dov dawb, lub pob bimetallic dawb paug yog compounded mus rau hauv ib qho hniav dawb nyob rau hauv qhov kev txiav txim siab kub thiab kub siab.
Cov teeb meem thiab qhov tsis zoo ntawm kev kos duab ua ntej muaj raws li hauv qab no: Vim muaj cov roj av ntau dua li welded, ua ntej muaj kev sib tw ua ntej yuav tsum tau saws. Ib qho ntxiv, Argon arc vuam lossis lwm cov roj av vuam hlau yuav tsum tau saws. Tsis tas li ntawd, txij li cov neeg hlau siab siv hlau loj ncaj qha welded, cov vuam feem yuav tsum yog nyob rau hauv lub xeev pov, uas cuam tshuam rau lub zog ntawm ntug. Nyob rau tib lub sijhawm, qhov ua tau ntawm vuam cracks ntawm lub weld kuj tseem loj, uas yuav cuam tshuam rau cov tshuaj sib xyaw ua zoo.
