Cov tsheb niaj hnub no yog nruab nrog lub thawv roj av. Lawv muaj ntau qhov zoo dua li cov hlau: qis dua qhov hnyav, zoo siab corrosion tsis kam, niaj hnub pom. Ib qho ntawm qhov tsis zoo yog tias nws yuav yooj yim dua rau qhov tawg txawm muaj qhov cuam tshuam. Ntawm qhov tod tes, lub taub yas yas yog qhov yooj yim dua rau weld rau tshaj li cov hlau.
Tsim nyog
- - chav ci thiab sov so;
- - paj ntaub rooj;
- - soldering hlau tsawg kawg 60 W;
- - txiav plaub hau;
- - riam;
- - txiab rau hlau
Cov Lus Qhia
Kauj ruam 1
Nco ntsoov sau cov hnab yas yas sib tsoo tam sim ntawd tom qab qhov sib tsoo. Koj yuav xav tau lawv yog tias koj tsoo nws. Tam sim ntawd ua ntej kho, tshem lub pob ntawm lub tsheb thiab txiav txim siab nws cov qauv. Yog hais tias lub bumper yog rubber-propylene, nws yuav tsum tau xaws los yog nplaum. Yog tias nws yog yas, nws tuaj yeem txuas tau.
Kauj ruam 2
Saib sab hauv ntawm lub bumper rau kev ntseeg siab ntxiv. Koj yuav tsum pom cov mis nrog PP, EPDM cov cim qhia tias cov khoom yog weldable.
Kauj ruam 3
Tso cov pob ntawv siab rau ntawm haujlwm tawm thiab kwv yees li ntawm kev ua haujlwm. Xaiv cov naj npawb uas yuav tsum tau muaj cov hluav taws xob zoo tib yam los ntawm cov kav hlau, cov khoom seem ntawm tsheb, thiab lwm yam. Yog tias koj tsis muaj kev paub dhau los ntawm kev kho cov thawv hluav taws xob, xaiv cov electrodes sim. Raws li koj tau txais kev paub, koj yuav kawm paub txiav txim siab cov electrodes yooj yim tshaj plaws rau txhua hom khoom siv.
Kauj ruam 4
Txhawm rau xaiv cov hluav taws xob kom raug, txiav ib daim ntawm cov khoom tawm ntawm sab hauv ntawm lub bumper thiab weld nws rov qab. Nco ntsoov sim ua ob peb yam sib txawv electrodes. Qhov zoo ntawm tus hlau txuas yog nyob ntawm txoj kev xaiv kom raug.
Kauj ruam 5
Tshem tawm cov av los ntawm kev sib koom tes kho. Rhaub cov hlau soldering rau kev ua haujlwm kub thiab ua kom sov ob qho ntawm ob qho ntawm cov npoo. Ua qhov no, pib tsav tsheb sting raws nqaws. Koom nrog ob tog ntawm cov leeg thaum txuas ntxiv xaub lub taub hau ntawm cov hlau soldering dua lawv. Thaum ob qho tib si thawb, ib tus zawj yuav tsum ua rau ntawm lawv qhov sib koom tes.
Kauj Ruam 6
Txiav ib qho electrode uas haum rau cov npoo ntawm qhov ntev thiab dav, muab nws daim duab peb sab hla ib sab, txiav nws cov lus kom mus ncaj rau ntawm rab koob. Qhib lub tshuab ziab plaub hau rau qhov kub thiab txias ntawm 250-300 degrees, sov cov hluav taws xob thiab pib vuam bumper raws txoj leeg nrog nws. Txuas txuas ntxiv kom sov cov electrode nrog lub tshuab ziab plaub hau thaum vuam. Lub electrode yuav tsum ua raws nraim cov zawj tsim. Qhov kawg ntawm lub weld, pib tig lub electrode hauv qhov zawj kom txog thaum nws tawg.
Kauj Ruam 7
Yog hais tias qhov kev puas tsuaj rau lub bumper tau dav dav, nco ntsoov txuas cov seam ntawm ob tog. Tom qab welding, ntxuav lub pob hlau sib tsoo nrog grinder los ntawm sab xub ntiag. Tshav kub rau cov ceg tsim tom qab kev kho nrog tus txhuam plaub hau thiab txhuam nws, kom txias nws. Nruab qhov bumper uas raug kho ntawm lub tsheb.
