Kuj weldingtxoj kev tsim tau sai heev txij li thaum pib ntawm lub xyoo pua puv 19, tshwj xeeb tshaj yog nrog kev loj hlob ntawm kev lag luam tsheb thiab lwm yam lag luam, daim ntawv thov dav zuj zus.Raws li kev txheeb cais, txoj kev siv vuam tam sim no suav txog li 1/4 ntawm tag nrho cov khoom siv vuam.Nws yog ntxhib qhov chaw npaj, ib qho ntawm cov txheej txheem tsim khoom.

Ua ntej, qhov kev tiv thaiv vuam yog qhov xav tau rau lub siab los ua kom tiav qhov vuam, yog li txawm tias nws yog los ntawm cov txheej txheem sib koom ua ke los yog los ntawm qee qhov kev sib txuas ntawm vuam uas qhov vuam yog qhov yooj yim, thaum lub vuam vuam muaj qhov tseem ceeb heev qee qhov ntxiv. Cov yam ntxwv ntawm cov khoom siv vuam, uas yog welded tsis tas yuav ua cov koom haum pab, lawv kuj tsis tas yuav siv cov xov hlau thiab cov rods rau vuam muab tub lim los ua qhov no, yog li txuag tau nyiaj ntau heev, tab sis kuj ua rau kom muaj txiaj ntsig zoo.

Qhov thib ob, kev ua haujlwm vuam yog ib qho kev ua haujlwm yooj yim uas, nyob rau hauv kev ua haujlwm yooj yim tib lub sijhawm, nyob rau hauv ib puag ncig vuam uas kuj muaj qhov zoo dua, feem ntau tuaj yeem ua tsis muaj pa luam yeeb.

Piv nrog rau cov pa welding tshuab, kuj welding muaj cov nram qab no zoo:
1) Thaum tshav kub kub yog concentrated, lub sij hawm cua sov yog luv luv, me me vuam deformation.
2) metallurgical txheej txheem yog yooj yim, thiab feem ntau tsis tas yuav sau cov khoom thiab hnyav tsis tsim nyog los tiv thaiv cov roj.
3) tuaj yeem hloov kho rau ntau hom zoo sib xws thiab sib txawv ntawm cov hlau vuam, nrog rau cov vuam ntawm cov phaj hlau plated.
4) Cov txheej txheem yog yooj yim, yooj yim rau kev siv tshuab thiab automation, kev ua haujlwm ua ntej tsis tas yuav muaj kev cob qhia ntev ntawm cov welders.
5) welded nrog cov khoom lag luam siab thiab tus nqi qis.
6) ib puag ncig ua haujlwm zoo dua thiab muaj kuab paug.
