Kev npaj ua ntej vuam: qhov chaw ntawm lub raj square yuav tsum tau nruj me ntsis ntxuav ua ntej welding kom tshem tawm xeb, av thiab lwm yam impurities, thiaj li tsis txhob cuam tshuam rau cov vuam zoo. Nyob rau tib lub sijhawm, tshem tawm tag nrho cov roj, plua plav thiab lwm cov khib nyiab nyob ib puag ncig ntawm txoj haujlwm vuam kom ntseeg tau tias cov khoom siv vuam thiab qhov chaw ntawm lub raj square tuaj yeem ua rau kev sib cuag zoo.
Kev xaiv cov khoom siv: Cov khoom siv vuam tsim nyog thiab cov cuab yeej siv yuav tsum raug xaiv raws li qhov yuav tsum tau ua ntawm vuam, thiab xyuas kom meej tias cov khoom siv thiab cov khoom siv no ua tau raws li cov qauv tsim nyog. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau xav txog cov khoom siv, tuab thiab vuam txoj haujlwm ntawm lub raj square thiab lwm yam txhawm rau txhawm rau xaiv cov khoom siv vuam tsim nyog thiab cov khoom siv.
Vuam txheej txheem: thaum lub square square yeeb nkab yog welded, yuav tsum tau them nyiaj mloog mus rau kev tswj lub vuam kub, vuam ceev thiab vuam theem kom lub vuam zoo. Thaum lub sij hawm vuam txheej txheem, cov kab nrib pleb, porosity thiab lwm yam tsis xws luag yuav tsum tau zam kom lub firmness, straightness thiab kev zoo nkauj ntawm lub vuam. Tsis tas li ntawd, rau cov rooj plaub uas yuav tsum tau welded los yog qhov chaw welded kom muaj kev ncaj, kev ua haujlwm raug yuav tsum tau ua kom ntseeg tau.
Kev kho tom qab vuam: Tom qab vuam tiav lawm, kev kho cua txias yuav tsum tau ua raws sij hawm kom tsis txhob deformation los yog tawg vim overheating ntawm weld channel. Nyob rau tib lub sijhawm, cov tsos ntawm cov vuam raug tshuaj xyuas thiab cov khoom siv sab hauv raug kuaj xyuas kom ntseeg tau tias qhov vuam zoo ua tau raws li cov qauv thiab cov kev cai.
