Plaub ntawm cov yam ntxwv tseem ceeb uas cov kws tshawb fawb metallurgists nco ntsoov thaum welding stainless hlau yog qis dua melting kub, qis coefficient ntawm thermal conductivity, siab dua coefficient ntawm thermal expansion thiab hluav taws xob ntau dua nyob rau hauv kev sib piv nrog rau feem ntau carbon steels. Cov kws tshaj lij stainless hlau welding feem ntau siv lub dab dej kub ua los ntawm txhuas lossis tooj dag, clamping cov khoom qab ntawm qhov sib txuas ntawm cov vuam kom nqus cua sov thiab tiv thaiv kom tsis txhob hlawv.
Feem ntau, stainless hlau welders siv cov cua sov tsawg li sai tau, tshwj xeeb tshaj yog thaum ua hauj lwm nrog cov khoom nyias. Thaum ua cov hlau thaiv arc vuam, stainless hlau welders feem ntau xaiv ntawm ob hom electrode txheej txheej: titanium-hom txheej thiab cov kua qaub-hom txheej. Cov coatings hom txiv qaub muaj qhov rov qab polarity, thaum titanium-type coatings yog haum rau siv nrog zoo ncaj qha tam sim no los yog alternating tam sim no. Feem ntau, titanium-type coatings muaj ntau dua rau cov welders.
Stainless hlau welders feem ntau siv tungsten arc vuam rau nyias ntu ntawm stainless hlau. Argon muab kev tiv thaiv roj, txawm hais tias kev siv tsis siv neeg tuaj yeem siv sib xyaw ntawm argon thiab helium.
Gas hlau arc vuam yog nrawm dua li lwm hom kev vuam txheej txheem. Vim li no, welders feem ntau siv nws rau cov ntaub ntawv tuab.
