Kariya don amfani da kayan walda
1. Galibi nau'ikan na'urorin lantarki iri biyu ne: nau'in titanium-calcium da nau'in ƙarancin hydrogen. A waldi halin yanzu rungumi dabi'ar DC wutar lantarki kamar yadda zai yiwu, wanda yake da amfani ga shawo kan ja da kuma m shigar azzakari cikin farji na walda sanda. Electrodes tare da titanium-calcium shafi ba su dace da duk wani matsayi na waldi ba, amma kawai don walƙiya mai laushi da walƙiya fillet; Za a iya amfani da na'urorin lantarki tare da ƙananan murfin hydrogen don walda duk matsayi.
2. Bakin ƙarfe na lantarki yakamata a bushe lokacin amfani. Don hana lahani irin su fasa, rami, da pores, nau'in nau'in titanium-calcium yana bushe a 150-250 ° C na awa 1 kafin waldawa, kuma an bushe nau'in nau'in nau'in nau'in hydrogen a 200-300 ° C. 1 hour kafin walda. Kada a bushe akai-akai, in ba haka ba fata za ta fadi cikin sauƙi.
