Selection na walda lantarki bisa ga sinadaran abun da ke ciki, inji Properties, anti-fatsa yi bukatun, a lokaci guda, la'akari da walda tsarin, karfe kauri, aiki yanayi, danniya, waldi yi da sauran dalilai m bincike.Lokacin da ya cancanta, yi gwajin walda, tsara matakan fasaha masu dacewa, sannan ƙayyade zaɓi na lantarki.
The carbon karfe walda lantarki da za a kullum amfani da ƙarfin karfe maki, la'akari da hadaddun tsarin, farantin, babban stiffness, tsauri kaya, matalauta waldi, kullum amfani a cikin filastik, high tasiri tauri, crack juriya yi kyau na low hydrogen electrode. , misaliE7018,E7016.Idan akwai buƙatu na musamman don matsayin walda, ta yin amfani da madaidaicin na'urar lantarki ta musamman, kamar lantarki, ƙasan wutan lantarki na walƙiyar a tsaye da dai sauransu misali. E6011, E6010.Domin inganta aikin walda, ana iya amfani da lantarki foda na ƙarfe.
Sai dai adadin sanyaya walda da sauri, ƙara ƙarfi, fasa walda yana da sauƙin samarwa.A lokaci guda, zai iya zaɓar ƙarfi fiye da ƙananan ƙarfe na tushe na lantarki;low carbon karfe da low gami karfe tsakanin dissimilar karfe waldi, karfe ne kullum amfani da low tsanani matakan m da lantarki da kuma la'akari low-alloy karfe factor, don zaɓar low hydrogen irin ya dace.
Domin walda na carbon karfe, saboda da karfe dauke da high carbon abun ciki, da kara waldi crack hali, kullum amfani da low hydrogen lantarki da preheating, jinkirin sanyaya hanya da kuma m waldi tsari matakan, za ka iya zabar.E6013, J422da sauransu..
Game da jefa karfe waldi, dauke da mafi girma carbon abun ciki, nauyi workpieces, hadaddun tsarin, shi ne mai sauki don samar waldi crack, a lokacin da karfe gami kashi na dogon lokaci, shi ne mafi shahara.General selection na low hydrogen irin waldi lantarki, da kuma dauki preheating, jinkirin sanyaya da sauran hanyoyin da daidai walda tsari da sauran matakan.
Shin shi ne don tabbatar da walda ingancin da a kan workpiece weld zai zama mai tsabta, babu mai, tsatsa, danshi, Paint da datti, da dai sauransu, a kan yin amfani da low hydrogen electrodes ne musamman muhimmanci.
(Na low hydrogen electrodes, walda lantarki za su kasance da 350 DEG C yin burodi na 1 hour, kuma tare da bushewa tare da amfani, ko da sauki don samar da porosity, slag, fasa da sauran lahani. The cellulose electrode kullum baya bukatar a gasa. , idan danshi, bisa ga umarnin manual zafin jiki waldi kafin yin burodi, amma yawan zafin jiki ya yi yawa zai halakar da aikin walda aiki.
