Kev ua haujlwm vuam yog ib qho kev xav tau ntawm cov cuab yeej siv kev nyab xeeb, vim tias nws yuav tsis tsuas yog raug kub hnyiab, tab sis kuj muaj lwm yam kev phom sij xws li cov khoom hnyav, cov pa phem, hluav taws kub nyhiab los ntawm kev sib tsoo, thiab lwm yam, los tiv thaiv vuam zoo. Kev ua haujlwm ntawm kev lag luam muaj kev phom sij, lawv yuav tsum hnav cov khoom tiv thaiv kev ua haujlwm uas tsim nyog, xws li cov khoom tiv thaiv qhov muag, cov khau siab kub thiab lwm yam.
Thaum tus welder ua qhov kub thiab txias siab vuam los yog fusion txiav ntawm qee daim hlau, hnav khau kev nyab xeeb nrog kub tsis kam tuaj yeem tiv taus kub kub kub thiab txaws sparks. Vim tias qhov kub thiab txias tiv thaiv kev nyab xeeb khau yog ua los ntawm cov khau siab kub thiab cov tawv tawv, lawv tiv thaiv ob txhais taw los ntawm kev kub siab ua haujlwm xws li cov hlau molten thiab raug kub hnyiab los ntawm kub kom tsis txhob raug mob.
Nyob rau hauv lub khw muag khoom hluav taws xob welding, qee qhov loj steel phaj feem ntau muab tso rau. Thaum tus welder ua hluav taws xob vuam ntawm cov phiaj no, cov hlau phaj yuav tsis ua mob rau lub phaj thiab yuav ua mob rau ko taw. Cov khau kev nyab xeeb nrog kev tiv thaiv kev ua haujlwm yog nruab nrog lub taub hau sab hauv uas tiv taus qee qhov cuam tshuam rau ntawm tus ntiv taw, thiab lub taub hau sab hauv yog muab tso rau hauv nruab nrab ntawm cov khau thiab khau, uas tuaj yeem txo qhov kev puas tsuaj ntawm cov khoom ntog. ko taw.
Ntxiv nrog rau kev ua haujlwm vuam hauv lub tshuab hluav taws xob vuam rhiav, qee cov welding tseem yuav tsum tau ua haujlwm vuam nyob rau hauv cov cheeb tsam. Qhov chaw ua haujlwm dav dav hauv cov nroog loj yog qhov nyuaj. Thaum cov neeg ua haujlwm vuam tsis hnav khau tiv thaiv kev nyab xeeb, txhais taw tau yooj yim ntsia. Iav slag pierces lub ib leeg. Cov khau tiv thaiv kev nyab xeeb yog vim tias cov ntawv hlau tau muab tso rau saum ib leeg, kom cov ko taw tuaj yeem tiv thaiv kom tsis txhob raug tho los ntawm ntau yam khoom ntse, thiab ko taw muaj kev tiv thaiv zoo los xyuas kom muaj kev nyab xeeb ntawm kev ua haujlwm.
Tus neeg siv hluav taws xob vuam siv zog txhawb kev tiv thaiv tus kheej thiab tuaj yeem tiv thaiv kev puas tsuaj ncaj qha lossis tsis ncaj rau tib neeg lub cev los ntawm kev ua haujlwm vuam. Kev siv cov hnab looj tes tsim nyog, hnav khaub ncaws tiv thaiv, kub kub thiab tiv thaiv kev nyab xeeb khau, qhov ncauj qhov ntswg, thiab lwm yam, tsis raug tso cai nyob rau hauv rooj plaub ntawm kev tiv thaiv engineering, thiab muaj kev nyab xeeb rau cov neeg ua haujlwm. Ib qho thaiv.
Tus welder tseem yuav tsum tsis tu ncua txhim kho kev paub txog kev tiv thaiv thiab hnav cov cuab yeej tiv thaiv tsim nyog rau qhov xwm txheej tshwj xeeb. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum tau ntxiv dag zog rau kev saib xyuas kev ua haujlwm ntawm qhov chaw vuam thiab kev tshuaj xyuas lub cev ntawm tus welder, thiab tsis tu ncua xyuas cov khoom tiv thaiv kev ua haujlwm ntawm cov neeg ua haujlwm vuam kom pom thiab daws cov teeb meem hauv lub sijhawm.
