Kev kho mob tom qab cua sov
Tom qab vuam, cov vuam yog khaws cia kom sov thiab maj mam txias kom txo tau qhov txias txias thiab tiv thaiv cov kab mob khaub thuas. Nws yog tsim rau cov ntaub ntawv xws li low-alloy high-strength steel.
Kev kho cua sov tag nrho
Tom qab lub vuam yog rhuab thiab khaws cia sov tag nrho los yog ib nrab, nws yog qhov cub txias los yog cua txias kom txo cov vuam seem ntawm kev ntxhov siab thiab txhim kho cov qauv thiab kev ua tau zoo ntawm thaj chaw weld thiab tshav kub.
Weld ntxuav
Tom qab welding, tshem tawm slag, spatter thiab lwm yam impurities nyob rau hauv weld nto nyob rau hauv lub sij hawm. Koj tuaj yeem siv cov cuab yeej xws li txhuam hlau thiab cov shovels los ntxuav. Rau slag uas nyuaj los ntxuav, kev sib tsoo tshuab kuj siv tau. Lub vuam nto tom qab ntxuav yuav tsum du thiab zoo huv si, uas yog yooj yim rau kev soj ntsuam zoo tom ntej thiab kev kho los tiv thaiv corrosion.
Kev kuaj tsis muaj kev puas tsuaj
Raws li qhov yuav tsum tau ua ntawm API 5L tus qauv thiab cov lus qhia tshwj xeeb, kev sim tsis ua kom puas tsuaj yog ua tiav ntawm qhov vuam. Feem ntau siv cov kev sim uas tsis muaj kev puas tsuaj xws li kuaj hluav taws xob (RT), kuaj ultrasonic (UT), kuaj cov hlau nplaum sib nqus (MT), thiab lwm yam. qhov vuam; Kev kuaj ultrasonic tuaj yeem kuaj pom qhov tsis xws luag hauv qhov vuam; Sib nqus particle kuaj yog tsuas yog siv los xyuas qhov tsis xws luag xws li cov kab nrib pleb ntawm qhov chaw thiab nyob ze ntawm qhov chaw ntawm qhov vuam. Qhov kev faib ua feem thiab cov qauv tsim nyog ntawm kev xeem tsis muaj kev puas tsuaj yuav tsum ua raws li cov qauv kev cai. Piv txwv li, rau qee cov kav dej tseem ceeb, 100% kev kuaj hluav taws xob yuav tsum tau ua.
Kev tshuaj xyuas qhov tshwm sim
Tshawb xyuas qhov pom ntawm qhov vuam, suav nrog qhov siab tshaj qhov siab, qhov dav, qhov chaw tiaj tus, kev sib tsoo, thiab lwm yam. Lub vuam vuam yuav tsum feem ntau tsis pub tshaj 3 hli, qhov dav yuav tsum tsis sib xws, qhov saum npoo yuav tsum tsis txhob muaj qhov tsis xws luag xws li pores, slag inclusions. , cov kab nrib pleb, thiab tsis muaj fusion, qhov tob hauv qab yuav tsum tsis txhob siab tshaj 0.5mm, thiab qhov ntev txuas ntxiv yuav tsum tsis pub tshaj 100mm, thiab tag nrho ntev ntawm cov undercut ntawm ob sab yuav tsum tsis pub tshaj 10% ntawm qhov ntev weld. Los ntawm kev tshuaj xyuas qhov tsos, nws tuaj yeem txiav txim siab ua ntej seb qhov zoo ntawm qhov vuam ua tau raws li qhov yuav tsum tau ua.
