Cov Txheej Txheem: hauv qhov kev tsim khoom ntxiv no, tus kws tsim khoom sib txuas ua ke ob lossis ntau dua cov hlau sib xyaw ua ke los ntawm kev teeb tsa ruaj khov. Vuam tshuab tseem pab nrog txiav hlau.
Cov txiaj ntsig: cov khoom sib dhos tsim nyog tuaj yeem tswj hwm kom ruaj khov. Qhov kev ua haujlwm no tau ua pov thawj kom muaj txiaj ntsig hauv kev txiav lossis koom nrog feem ntau ntawm cov hlauWelding yog ib qho ntawm kev pib ua ntej rau kev koom nrog cov hlau, uas koom nrog ua kom sov cov hlau ua kom tiav (hauv daim ntawv ntawm cov muab tub lim hlau) kom yaj nws thiab sau qhov sib koom ua ke. Mos muag hlau yog cov txheej txheem yooj yim tshaj plaws thiab yog ib txoj kev siv los kho cov khoom me me ntawm tsev thiab ib puag ncig. Qhov no tseem yog li cas cov kav dej txuas thiab kho cov kav dej tooj liab thiab fittings. Koj tuaj yeem siv cov qis hlau soldering hlau lossis blowtorch nrog lub ntsej muag haum rau soldering. Lub vuam khov cuam tshuam txog cov cua sov muab cov khoom ua kom sov siab dua, yog li qhov sib koom tes yuav muaj zog ntau dua li lwm cov sib txuas welded. Cov ntaub ntawv nplua nyiaj tau sib txawv thiab feem ntau muaj nyiaj, yog li cov txheej txheem no feem ntau hu ua nyiaj brazing. Txawm li cas los xij, kev sib tsoo tiag tiag yog nqa tawm ntawm qhov kub siab dua. Brazing yog qhov tseem ceeb rau cov txheej txheem ua kom sib xyaw uas siv cov khoom siv sib dhos zoo ib yam (xaim lossis bar) raws li txhuam. Cov pob qij txha yuav tsum sib txuas zoo sib xws kom qhov capillary kev ua haujlwm tuaj yeem nyiam cov hlau sau nruab nrab ntawm cov ntawv txuas tooj liab. Lub hauv paus hlau yuav tsum tsis txhob raug rhaub rau qhov melting point txawm hais tias qhov ntsuas kub siv yuav tsum muaj ntau dua qhov uas yuav tsum tau ua rau kev vuam. Tho pas nrig
