Cov khoom siv raw ntawm cov kav hlau welded yog cov pa roj carbon tsawg tsawg, cov hlau tsis tshua muaj hlau lossis cov hlau manganese siab, thiab lwm yam, uas tau siv dav hauv boilers, tsheb, nkoj, lub teeb steel qauv qhov rooj thiab qhov rais, rooj tog, ntau yam kev ua liaj ua teb machinery, high- nce rhawv, ntim, thiab lwm yam. Yog li dab tsi yog qhov kev ceev faj thiab kev lees paub rau kev yuav cov kav hlau welded?

Kev ceev faj rau kev yuav khoom welded steel kav:

1. Tshawb xyuas cov chaw tsim khoom tsim nyog, seb daim ntawv tso cai ua lag luam, daim ntawv pov thawj ntawm lub koom haum, daim ntawv pov thawj sau se, daim ntawv tso cai tsim khoom thiab ua haujlwm thiab lwm yam ntaub ntawv tsim nyog tau ua tiav.
2. Saib cov ntaub ntawv, tshuaj xyuas qhov kev ua tau zoo ntawm tus neeg xa khoom, thiab cov xwm txheej ntawm cov haujlwm uas tau ua haujlwm yav dhau los.
3. Puas muaj ib lub nkoj thauj khoom tus kheej?Kev xaiv ib tus neeg muab kev pabcuam nrog lub nkoj thauj khoom tus kheej tuaj yeem txo cov nqi thauj mus los, thiab qhov tseem ceeb tshaj plaws yog ua kom cov khoom xa tuaj raws sijhawm.

4. Kev pab cuam tom qab muag, seb puas muaj lub suab nrov thiab txhim khu kev qha tom qab kev muag khoom lav qhov system, thiab cov teeb meem zoo hauv kev lees txais cov khoom thiab kev siv tom qab yuav tsum tau daws raws sijhawm.

Txais cov qauv rau welded steel kav:

1. Xyuas seb cov ntaub ntawv pov thawj zoo xws li daim ntawv pov thawj cov khoom zoo, cov khoom siv phau ntawv, thiab phau ntawv pov thawj zoo puas tiav.
2. Txheeb xyuas qhov zoo li ntawm cov yeeb nkab welded, qhov saum npoo yog du thiab tiaj tus, lub vuam seam yog ntom yam tsis muaj burrs, tsis muaj roj qhov chaw corrosion, tsis muaj extrusion deformation, thiab ntu ntu yog tiaj tus.
3. Siv lub micrometer los xyuas seb qhov txheej sab nraud thiab phab ntsa tuab ntawm cov yeeb nkab welded puas tau raws li qhov yuav tsum tau ua, thiab qhov sib txawv ntawm cov qauv phab ntsa thickness tsis tshaj 3% -5%.
4. Siv lub ntsuas qhov tsis zoo los ua qhov tsis muaj kev puas tsuaj rau cov kav dej welded.
5. Ua tiav qhov kev ntsuas lub zog tensile raws li qhov yuav tsum tau ua, khoov cov yeeb nkab welded 30 degrees, thiab tsis muaj qhov tawg ntawm qhov khoov.
