Txoj kev teeb tsa ntawm cov kav hlau stainless yog qhov tseem ceeb tib yam li cov pa roj carbon zoo tib yam, thiab muaj cov txheej txheem hauv qab no yuav tsum tau ua hauv qee cov txheej txheem.
1. Cov khoom siv stainless hlau yuav tsum tsis txhob sib cuag nrog lwm cov hlau, thiab yuav tsum tau padded nrog cov ntaub ntawv uas tsis yog xim hlau xws li ntoo boards lossis cov ntawv roj hmab.
2. Nws tsis raug tso cai siv lub log sib tsoo zoo tib yam rau cov yeeb nkab txiav, thiab cov hlau tsis muaj steel tshwj xeeb sib tsoo lub log lossis cov plasma txiav yuav tsum tau siv.
3. Sab hauv ntawm lub vuam yuav tsum tau tiv thaiv los ntawm argon thaum lub sij hawm tack vuam ntawm stainless hlau kav thiab fittings.
4. Lub arc pib, arc xaus, thiab arc pib txais cov txheej txheem reflow, thiab arc xaus yuav tsum sau cov arc crater. Lub arcing yuav tsum tau ua kom tiav nyob rau hauv qhov zawj, thiab arcing thiab arcing rau saum npoo ntawm cov khoom siv ntawm cov kav dej thiab cov yeeb nkab fittings raug txwv. Yog tias muaj qhov tsis xws luag xws li qhov pores thiab cov kab nrib pleb raug pom ntawm qhov pib thiab arc xaus, lawv yuav tsum tau muab ntxuav kom huv si raws sijhawm.
5. Rau kev sib txuas ntawm cov kav hlau tsis muaj steel, cov yeeb nkab fittings thiab stainless hlau kav, cov yeeb nkab fittings thiab cov yeeb nkab tsis-stainless thiab cov yeeb nkab fittings, cov welded pob qij txha yuav tsum tau ntim nrog argon roj tiv thaiv ua ntej vuam hauv qab, kom argon tungsten arc vuam. tuaj yeem ua tau.
6. Lub arc pib thiab xaus cov ntsiab lus ntawm multi-pass multi-layer vuam yuav tsum staggered ntawm ib leeg.
7. Thaum cov khoom siv steel hlau tsis tu ncua welded, lub interlayer kub yuav tsum tsis pub tshaj 60 degree.
8. Lub vuam seam ntawm qhov vuam sib txuas ntawm cov kav dej yuav tsum tau muab pov tseg thiab ua kom dhau tom qab vuam.
9. Kev ntsuas dej siab ntawm cov kav dej stainless hlau muaj qee qhov yuav tsum tau ua rau dej kub thiab dej zoo, thiab dej kub yuav tsum tsis pub tsawg tshaj 5 degrees Celsius; Cov ntsiab lus chloride ion hauv dej yuav tsum siab dua 25Pmm.
