Tus ua hauj lwm ua haujlwm ntawm txhuas ntawv diffusion vuam tshuab feem ntau yog cov kauj ruam hauv qab no:
Preheating theem: thaum tam sim no ntawm electrode phaj yog muab rau ntawm lub phaj tsis zoo ntawm lub phaj tsis zoo ntawm lub phaj zoo txuas ntxiv lub workpiece.
Lub ntsiab lus Circuit Court tseem ceeb: Raws li cov tam sim no ntawm ob lub xeem nce ntxiv mus txog thaum lub sijhawm no, qhov kev sib tiv tauj ntawm ob lub sijhawm ruaj khov, uas yog qhov chaw ua haujlwm tseem ceeb thaum lub sijhawm vuam .
Sau theem: Thaum qhov sib txawv ntawm ob tus ncej raug txo kom muaj nuj nqis, lub arc pib sau cov khoom siv vuam, thiab cov khoom siv molten tau nias rau hauv cov khoom .
Arc extinction theem: raws li cov nqi tsis zoo thiab tsis zoo tau txuas ntxiv, lub arc maj mam txhaj tshuaj .
Txias theem: Tom qab vuam yog ua tiav, lub workpiece nkag mus rau hauv cov roj cua txias. molten hlau los ua kom muaj zog weld sib koom {}}
